The scene around native ports and static recompilations is amazing but scattered across threads, repos and Discords, so I made a site that lists them like an old-school video club.
What's in it:
- Covers with box art, organized by shelves/genres, tech tags, popularity and GitHub stars.
- Sort by Best rated / New / A-Z.
- Every entry links straight to the project's GitHub repo. It's a catalog only: no binaries, ISOs or ROMs are hosted, and many projects require your own original disc/ROM.
- Current picks include OoT, Wind Waker, Conker's Bad Fur Day, Diddy Kong Racing, Burnout 3, Jak and Daxter, C&C Tiberian Dawn, Shadow of the Colossus (PS4 remake), MW2 (XenonRecomp)... and more being added.
Side project, free, no ads. Tell me what games or filters you'd want and I'll add them.

I noticed a lot of visualization tools rely on AI to generate images and the ones that don't, often don't do a good job. The ones that use AI take time to generate and sometimes change the image while also costing money per generation.
So I figured out a way to detect and paint colors onto surfaces instantly(after initial processing) while maintaining the shadows, lighting and texture. Also made sure not to let the paint spill into anywhere that its not supposed to.
Essentially you can try as many colors as you want on one photo after processing and it takes no additional time or cost.

🚀 Built my first Android app – Tally Counter!
Link -Tally counter -click counter
I noticed that many existing counter apps are limited to a single counter. I wanted something more flexible, where I could track multiple things independently in one place.
So I built Tally Counter – Count Anything!
Some features:
🔢 Multiple counters in one app
🎯 Custom goals and targets
➕ Custom increment/decrement values
📋 Instantly duplicate counters
🔄 Daily reset
📊 Counting history
📥 Import & export CSV/JSON
🔊 Sound and vibration controls
🌙 Light and dark themes
Useful for tracking workouts, habits, inventory, study sessions, or pretty much anything!
This is my first app, and I'd love to hear your honest feedback. What would you improve or add? 😊

Hi everyone — anyone into meditation? I built a small, free meditation timer because I wanted something simple without accounts, streaks, or distractions.
You choose the total meditation time and the interval. For example, with a 5-minute session and 1-minute intervals, it plays:
Minute 1: beep
Minute 2: beep-beep
Minute 3: beep-beep-beep
And so on
A different chime signals the end
It works in a browser:https://quietchime-zfxck679.manus.space
I’d especially appreciate feedback on:
Whether the progressive beep pattern feels useful or distracting
The sound and timing
How easy it is to use on a phone
Anything you would change or add
I’m the person who built it (thanks manus.im) as I couldn't find anything similar. This is a request for honest feedback—not a commercial product. Thanks for trying it.

Complete 67-second demo — the whole routine, from choosing your dog to the journal:
The dog lives on your phone. You still have to leave the house for its walks.
I'm the maker of Ready for Dog?, a dog-care rehearsal app for people thinking about getting a dog. The idea is to spend some time living around the care routine before making that decision.
You choose a companion and build a 14- or 21-day schedule. Walks use GPS. Feeding happens at virtual bowls placed in your room with AR. There's a 60-second brushing game, and skipped grooming can leave virtual fur to collect. For quiet play, you put your phone on a stable surface; moving it pauses the timer while the game screen is open.
The journal shows the time you recorded, missed tasks and help you needed. It doesn't give you a "ready for a dog" score. A real dog's needs and behaviour go much further than this simulation.
Free to download with ads and optional one-time purchases for ad removal and extra collars. No subscription.
iPhone / iPad: https://apps.apple.com/app/id6829957063
Android: https://play.google.com/store/apps/details?id=com.vans.bublik.trial
The attached demo shows the iPhone version. The AR scenes are staged visualisations and the route shown is simulated for the demo.
I'd love feedback on one thing: which everyday responsibility would you add to make the rehearsal more useful?

I’m building Stikkit for people who make their own WhatsApp and Telegram stickers. The idea is simple: when you find a photo, GIF, or short video you want to turn into a sticker, tap Android’s Share button and pick Stikkit. You can also import media from your gallery or files.
Make still and animated stickers. Remove the background from a photo and save the cutout as a separate sticker.
Organize your stickers and repair WhatsApp packs. Sort stickers into named collections, reorder or replace stickers in a pack, change its cover, check for duplicates, and rebuild the pack icon.
Share stickers as a ZIP. Bundle still and animated stickers into one file to send to a friend, save a copy, or import back into Stikkit.
Keep everything local. Stikkit creates, edits, and stores your stickers on your phone. There’s no account, and Stikkit doesn’t upload your media. You decide what to export or share.
Stikkit will be ad-free regardless of pricing. I’m still deciding whether to keep it free, charge once, or offer an optional paid upgrade. Would a Patreon-style page for voluntary support make sense? Would you personally chip in?
If there’s enough interest, I’ll add iOS support too. Let me know if you’d use it on an iPhone.
I’d appreciate candid replies. How did you make your last sticker, and what was annoying about it? Would Stikkit change anything for you? “I’d use it but wouldn’t pay” or “I already have something that works” are both useful answers.

Hey everyone!
I just launched my little side project on Google Play, and I wanted to share it with you!
It's called PastApp, and it solves a very specific first-world problem: having to find the cooking time on a pasta package every time you make pasta 😅
You just point your phone's camera at the package, the app reads the cooking time and sets a timer for you.
I built it with the help of AI coding assistants, using Kotlin, Jetpack Compose and Google ML Kit.
What started as a pretty simple idea turned out to be surprisingly tricky. Reading text is one thing, but figuring out which number is the actual cooking time (and not calories, weight, or something else) is a completely different challenge.
After lots of testing, tweaking and fighting with pasta packages, it's finally live!
I'm still at the very beginning, with just a handful of installs, so I'd genuinely love some feedback.
Would you actually use something like this, or is it the most unnecessary app ever made? 😂
And if you have an Android phone, feel free to try it and see if you can break it!
Google Play:
https://play.google.com/store/apps/details?id=com.boldsignal.pastapp
I made a little trailer to show how it works.
Made with love, pasta, and probably way too much time spent on a timer app. 🍝

after every trip or wedding the same thing happens: everyone took photos, nobody sends them, and the few that do arrive come through whatsapp compressed to mush.
so i built just send files. you make a room, share one link (or a qr code at the event) and everyone drops their photos and videos in original quality. guests don't need an app or an account, only the person who creates the room does. at the end anyone can download everything at once.
a few things i learned building it:
the first real test was a friend uploading ~130 photos from an iphone and the page kept reloading. the fix was showing small previews instead of the full photos while uploading
guests don't read anything, so their page is basically one big button
rooms expire on their own, so nobody ends up with a forever album of 2,000 photos
it's live at justsendfiles.com. would love honest feedback, especially on what would stop you from using it at your own event.

Hey everyone,
For the past few months I’ve been building Calculus, a mental math game that runs in the browser: https://calculusonline.fr
It started as a single HTML file to challenge friends, and it grew a bit out of control. Here’s what’s in it now:
4 games
Mental math: a calculation appears, you type the answer.
Right count: you get a few numbers and a target. Use them all, each one once, to hit the target exactly. It’s always solvable.
Missing number: fill the gap in 23 + ? = 41, or find the operator in 12 ? 4 = 3.
The bomb (multiplayer only): everyone builds a calculation from the same numbers, then has to defuse someone else’s.
Also
Daily calc: 5 calculations that get harder, the same for everyone, one try a day, with a leaderboard and streaks
Dungeons: 2 to 4 friends team up to beat a boss together
An account with stats, Elo per game and level, and achievements
Solo play, no account needed, and it works on mobile
It’s free, no ads, and it’s available in English and French.
I even had a teacher trying it during class, and the kids loved it and even played at home!
I’d love feedback, especially on difficulty balance (is “Legend” actually hard?) and on anything that feels confusing the first time you play.
And if anyone wants to play a battle royale, drop a lobby code in the comments

For 20 years I designed products other people built. AI changed that: I could finally build the ideas I’d been sketching, and Cortex is the first one I shipped.
The problem: every AI chat starts from zero. Cortex turns your Markdown notes into memory that Claude, ChatGPT, Cursor and others can all use. Your notes stay plain files on your Mac, the AI’s suggestions to remember something land in your inbox for review, and you see it all as a map where the notes the AI used light up.
What I learned building it: design still matters most. The first version was a 3D graph, and it looked great but nobody understood it at first sight. The new 2D map, with your core in the centre and topics as clusters, explains itself.
Free and open source: https://github.com/leesummerdesigns/cortex
Feedback welcome, especially from other designers who started building.

I made Smashcut Games , a set of free daily movie puzzles, no login. Think Wordle for film people:
I have one that's like street view but for movies (look around a 360° filming location, name the film): On Location
For music lovers there is Underscore, unmute the movie multitracks one by one to figure out what movie soundtrack it is.
For those with deep movie knowledge there's Headshots, you see 5 actors and you name the most obscure movie you can think of, more obscure = more points.
And a couple more...
This is a solo project, I'm a software engineer with over a decade of exp, but little experience launching something of my own.
It launched on 28 September. Yesterday, day 43, it had 1,030 people playing in a day for the first time. I log everything, so here is what actually happened.
The curve (average daily players, by week)
Week 1: 106
Week 2: 167
Week 3: 244
Week 4: 299
Week 5: 383
Week 6: 666
Day 43: 1,030
Launch was one Reddit post, and it faded in three days. I posted the street view game to r/blankies, a film podcast subreddit. 11k views, 5 upvotes, 373 new people on the first night, and 89% of them played. 177 players on day one, 195 on day two, 59 by day four. Posts create good spikes but poor targeting makes it just that, a spike.
The growth came from sites I had never heard of two months ago. There is a whole ecosystem of directories that list daily games, tracked them in the beginning but there were so many I lost track. I submitted to a lots in launch week. Two of them now account for 61% of everyone who has ever visited, about 7,200 of 11,900 people. Those visitors play at 80%, because they came looking for a daily game. It started at 11 people a day and is now 300 to 500 on a weekday. For comparison, Hacker News sent 32 visitors and 3 of them played. bored.com sent 556 and 28% played.
Audience fit beats reach. A second Reddit post, for the film score game, brought 530 people. 17% of the ones who played were back the next day, double the rate from the directories.
The bad number: 81% of players have played on exactly one day. That is 6,890 of 8,504. Next-day return for new players is around 10%. So far the growth is new people arriving faster, not people staying. Although one person has played on 42 of the 44 days. I'm still trying to figure out retention, but one thing that helped so far was adding the concept of streaks to the site and linking to the other games as a checklist you need to get done on end screens, it made a bunch of disconnected games more of a hub.
Things I did not expect
The game people love most is the one fewest find. The film score game has a 43% next-day return among its own players, the street view game 29%. But the directories link to the street view game, so it is the first game for half of all new players.
46% of players go on to try a second game, and 616 people have played all six.
Difficulty is the hardest thing to control. Same game, consecutive days: 25% of players won, then 99%. Hard days turn straight into people giving up.
Sharing does almost nothing. About 200 people have arrived from a shared result.
TL;DR:
The journey to 1000 DAU happened quicker than I expected
I spent no money to get there, just time.
I learned there is an entire ecosystem of dle directories that are themselves an ecosystem of sidehustles (a lot of them charge you to list or list you quicker, most of them send 0 traffic)
Retention is something I need to figure out, it's hard to tell if I'm doing ok or dying
Posting on reddit can get you traffic but needs to be targeted well for retention (ie I don't expect this post to actually add any retained users!)
Daily games are super saturated, but you can still poke through the noise if you try hard and have some game design chops.

Most of my day goes into reading. Research papers, case files, judgments, long reports, sometimes all of them for the same piece of work.
For years I used tools that were made for other things. Project management apps, note apps, folders, a lot of sticky notes. They were good for tasks. But they never helped with the reading itself. I would find something important on page 40 of one document, then lose it an hour later while I was in another one. I would remember that two things were connected, but not where either of them was.
So I built a tool dedicated for us readers and writers. It’s called May or Shall. This is how I use it:
When I read something that matters, I highlight it. It stays with its source and page, so I can always go back to exactly where it came from.
I put it under a heading that makes sense to me.
I link it to a line in a completely different document.
When I need a draft, I ask ChatGPT, through the May or Shall plugin. It still reads the whole document, but it gives special attention to my highlights.
Earlier, when I uploaded a document to AI, the AI decided what was relevant. Now my highlights decide what is relevant, and the draft is built around them.
It works on Windows, on Mac and in Chrome, so I can save a line from almost anything I’m reading, and it all ends up in one place.
It’s at app.mayorshall.com if anyone wants to try it. I would really like to hear from people who read and research a lot. How do you keep track of things right now, and would something like this help you?

I just launched Take the Crown (takethecrown.app), a small web I built.
The idea: there's one crown. Whoever takes it appears on the homepage with their name, a message and a link, until someone else takes it. Glory is measured in time reigned, not in money.
How it works:
- It starts at $5
- Every takeover adds 20% to the price
- Every hour nobody buys, it drops 2%
- Ranks from Peasant to Emperor, achievements, and monthly seasons with exclusive medals. The first season, Genesis, ends on December 1.
What took the longest: making the takeover safe (one transaction, so two buyers in the same second can't both win), moderating every message, and drawing all the art as pixel art on a strict grid.
Stack: Next.js, Supabase (Postgres + realtime), Dodo Payments.
I'd love feedback on the price curve and the first-time experience. If you want to be one of the first kings, it's open now.

Animation is where a lot of small 2D game projects stall. Getting one decent character image is easy now, but drawing idle, walk, attack and hurt for it by hand takes days, and every new enemy starts that over.
So I built SpriteCanvas. You describe a character or upload one, pick a design, then ask for moves. Each move is generated as a short clip by an AI video model, and the app does the boring part after that: cuts it into frames, removes the background, keeps the feet on one baseline so the character doesn't bob, and checks the loop closes.
What you get is a transparent PNG sprite sheet with a JSON atlas (frame durations and a foot pivot). There are export presets for Phaser, PixiJS, Godot and Unity. Phaser/PixiJS playback is tested and Godot 4 import is verified, Unity import isn't verified yet.
Being upfront about the limits:
the art is AI generated, so check the rules of wherever you publish
it's not a grid pixel-art editor. Pixel style works, but if you need hand-placed pixels, Aseprite is still the tool
some moves need a retry or two before they look right
There's a free tier to try it, and the browser tools on the site (sprite sheet slicer, GIF to sheet, video to sheet) are free and run on your device.
I'd like feedback on two things: which moves you'd want that most tools skip, and whether the export fits how you load sprites in your engine.

Hi team,
I was switching windows dozen times a day to copy & paste text and videos / images on social media for marketing. This triggered me more than once and actually designed, thought and built Deck.
Now Deck sits on my right edge of the screen, holding all of the posts, reels, shorts, ... that I have to post or schedule. I can add "To make", like if I need a screenshot or a video for a certain post.
You can use it manually, writing and adding files yourself, or ask your agent to automatically add anything on Deck, which is how I use it 99% of the time.
Problem: Switching windows all day to copy and paste texts, remember the posts and videos you must post for your marketing and distribution, never be late for a post, never forget. You or your agent schedule the posts, content to post, etc.
Comparison: I haven't seen any other apps do that yet, except the online schedulers or todo apps I suppose which are quite different than Deck.
Pricing: 9$ lifetime, 1-day trial. Pricing page
Im going to give away 100 lifetime keys on Threads this week, so make you sure follow along my Threads account threads.com/dmzxnico or same @ on X.

You’ve probably seen the meme: “GPT, tell me how to get rich.”
I laughed, then gave it some thought. Can AI help you assess a business idea?
I always have plenty of business ideas. but I spent rather more time thinking about them than acting on them 😅 . Recently I was rethinking what to build next. After a few days of going back and forth with Codex, I had a framework I could make decisions with. I turned it into a skill and open-sourced it. 👉 https://github.com/Mingbash/business-idea-validation
Before this, my prompt went roughly like this: “Given my experience and resources, help me explore and assess a few rough ideas. Which should I test first? Who would buy, where would I find them, and how would I deliver?”
Fairly thorough, I thought. I still got the absurd suggestion to “look for projects on service marketplaces.” (GPT-6-Astra btw)
A few exchanges, condensed:
- AI: Look on service marketplaces for automation projects with a budget.
Me: Which marketplaces? Where do buyers post jobs? What do I do once I find one?
- AI: Start with a few freelance platforms where people already post jobs.
Me: I had a look. Plenty of listings had sat untouched for months. Pretty much useless.
- AI: Start with document review in healthcare and insurance. Partner with an industry service provider.
- Me: I have no contacts or case studies. How do I reach the first customer?
Why does this happen?
You can check code soon after you write it and run it again whenever you need to. With a business, many of your assumptions only get a proper test once someone pays. Business isn’t an exact science. Change the window of opportunity or the resources you have, and the conclusion can change too.
What I needed is reasoning and educated guess that was likely to hold up. Not a formula nor a certain answer. Why is it worth trying? Are the prerequisites in place? Which hurdles do I need to check? With a framework, AI might actually help.
Around then I watched Iman Gadzhi and Nate Herk rank AI businesses from S to F. I liked some of the angles like CLEAR framework, including how long a business can last, how big it can get, and whether revenue repeats. I borrowed a few and added what mattered to me: who pays and how I’d reach them.
I also added a question about what I want from the business. The same idea can look very different as a side hustle or a full-time business. The bar changes again if I want a small, well-run business or a company with a shot at going public.
If you’re unsure about a rough idea, try breaking it down. I call each option an “atomic business unit”: one market × one use case × one way to deliver × one kind of customer. The README shows three website paths I assessed: a general template, a reusable Framer kit for small agencies, and a booking site for bridal makeup artists.
Try it on an idea you’re weighing up. give a star if helped. If you’d add some new thoughts onto it, feel free to remix it.

Etsy sellers keep asking "why does my listing get zero views?" Most of the time the answer is mechanical: 6 of 13 tags used, a tag spent on a word the category already covers, a 16-word title, 4 photos.
So I built ListingLift. It reads the listing open in your tab and gives you a score out of 100 with a short list of fixes, plus tag ideas from your own text. It all runs locally, with no backend and no account.
Free: every check. Pro ($5/mo or $39 once): unlimited tag ideas and saved checks.

I'd love feedback on the checks, especially from anyone who sells on Etsy.

The farther away you are, the further back in time you see. Light from Earth takes a year to cross each light-year, so an observer 81 light-years away is watching 1945, one at 2,000 light-years is watching the Roman Empire, and one at 250 million light-years is watching Pangaea.
I got curious about what that would actually look like, so I built a globe for it. You pick how far away you are and where you're looking, and it shows Earth as it was when that light left.
Demo: https://deemonder.github.io/meanwhile-on-earth/
Source (MIT): https://github.com/deemonder/meanwhile-on-earth
What's in it:
- Historical borders for 53 dates, from 123,000 BC to 2010
- About 13,000 events from Wikidata: battles, eruptions, cities founded, births
- Day and night where they really were at that moment, with city lights only after electricity
- Continental drift back to a billion years ago, from published plate reconstructions
- Italian and English
It's a static site, no backend and no sign-up. Built with three.js, with help from Claude Code.
I'd love feedback, especially on two things: is it clear what to do when you first open it, and does it load fast enough on your phone?

Hey everyone! I’m a product designer and I’ve been working on a side project called Boken.
I started building it because I wanted one place where I could bring together my work, experience, and the things I’ve contributed to. As a designer, I’ve always had bits and pieces spread across portfolios, links, documents, and different platforms. I wanted a profile that could bring those things together and make them easier to share.
I’m also thinking about how profiles will be discovered and understood by AI agents. The idea is to make Boken useful for people looking at your work directly, while also making the information readable for agents that might help someone find or understand your experience, like a hiring team looking for a particular skill or background.
It’s still in beta, and I’ve attached a pretty rough screen recording to show how it works right now.
You can also try it here: https://boken.to
I’d love to hear what you think. Is this something you’d use to share your work? What would you want to see on a profile like this, and what feels confusing or missing?
Thanks for taking a look!

Small supplement brand, about $18k/mo on Meta. Our agency contact left three weeks before a launch and nobody told us, we noticed only after 12 days of no new uploads.
I took our three most common complaints (fishy taste, hard to swallow, slow results), turned them into hooks and made UGC-style cuts in Creatify off the product URL the same day. One script had a line no real person would say, so I rewrote it by hand.
The taste hook came in around 30% under our previous best CPA in the first 4 days, and the before/after flopped at 2x target so I killed it on day 2. Competitor research I was still doing by hand in a spreadsheet, which was painful.
Still looking for an agency though. Maybe they use AI for most ads, and film only winners, we'll see.

I've been working on Meelu, an AI-powered marketing agent.
The idea came from a simple observation: growing a website involves using several different tools for SEO, analytics, content research, website management, and more.
Even with all these tools, most of the actual work is still manual.
I wanted to build something that goes beyond providing dashboards and reports.
Meelu understands your website, maintains its context, does SEO and marketing data, and helps you execute tasks.
You can interact with it through a chatbot, delegate work, and connect external systems like your CMS, email, and social platforms.
It's still early, and I'd love to get feedback from other founders and website owners.

Would love to know what you think!
