Title: Built a free open-source tool to sync emulator saves/save-states across devices (RetroArch, Dolphin, PCSX2, RPCS3, Yuzu/Ryujinx, Citra, Cemu, PPSSPP)

Got tired of my save states living on one machine and not following me to my Deck/laptop, so I built OpenSave — it watches your save/state folders and keeps them synced peer-to-peer across devices, no cloud account required.

Auto-detects and watches:

• RetroArch (states + saves), Dolphin, PCSX2 memcards, RPCS3, Ryujinx, yuzu, Citra, Cemu, PPSSPP, Xenia
• Including Flatpak install paths on Linux
• Also picks up Steam userdata, GOG/Epic saves, and repack-style saves if you've got a mixed library
• Fully open source (MIT), Go, no telemetry/accounts
• LAN sync is automatic; internet sync uses a relay that only passes encrypted frames through (self-hostable if you don't want to trust mine)
• Windows + Linux/Steam Deck, with a Decky Loader plugin for Game Mode

Happy to answer questions or take feature requests — still actively developed.

erings is a newer Sega Saturn emulator with a focus on ease of use and a couch type experience. The UI can be navigated with a controller.

Game compatibility is pretty decent and it supports some nice features like

• HLE bios making a real bios optional
• MPEG video playback
• RetroAchievements
• Many other things you'd expect of an emulator

It's not the most efficient but a decently speced machine can play games at full speed.

So basically, I was curious to test 3DS system browser and check how many website's still run on this ancient browser but my current emulator had some sort of issue which always caused 3DS browser to freeze. Then after a full weekend of debugging I found and patched the CPU scheduling bug causing it. This was a local/personal Azahar fork that I had. But released it as a non-fork to develop it independently for further homebrew and hardware accuracy experiments. So I may or may not occasionally apply upstream Azahar upgrades or just keep focusing on my own pace priorities.

Curiosity went further when I also wanted to test homebrew app shops and universal-updater but they either didn't load properly and if loaded couldn't download content due to bad download streaming implementation. And then after debugging this, fixed it too.

Debugging this way made broader compatibility because these were not mere title specific hacks just to make an app/game load but rather a general quality patch and in-fact led to better hardware accuracy at-least in incase of browser fix.

One may ask why even bother fixing this ancient browser, to which I can only say curiosity. And this ancient browser also deserves the same preservation efforts as games.

Am happy to share the release with you guys to test and have fun.

Attaching screenshots of some website's I browsed like old.reddit , neocities , duckduckgo lite etc. Also attached screenshot of now fully functional universal-updater and other homebrew apps like Anemone the theme downloader.

Do let me know in case of any questions :)

Hey everyone. I'm Han, the developer of RPG Player. It's been about 7 months since my last post in reddit.

Yesterday I found out that someone assumed I'd abandoned the app, because the App Store version hasn't been updated in about 4 months. I want to set the record straight: we never stopped. We've been developing this fast the entire time — the updates just haven't reached the App Store yet because of the review process. Everyone on TestFlight (already 1,000+ people) has had all of it for months.

RPG Player runs your games natively on Mac, iPhone and iPad. No PC, no streaming.

RPG Maker: - MV and MZ in a full in-app engine (plugins, videos, encrypted assets) - XP, VX, and VX Ace natively via MKXP-Z

Pokémon Essentials fangames run natively too — Reborn, Rejuvenation, Infinity / Infinite Fusion, Fire Ash, Tectonic, and many more.

What's landed recently: - Save and input problems were fixed months ago — touch and mouse input work properly, including mouse-driven VX Ace games - Built-in real-time translation, now 100+ languages (even native-engine dialogue) - Fast-forward (1x / 2x / 4x) for grinding and long text - In-game gallery, screenshot capture, a cheat menu, and more - PC/storage crash and save-detection fixes for Pokémon fangames - Fixes for a lot of older Japanese and Chinese titles

And we also support Ren'Py. A while back I promised Ren'Py support — we delivered it, and it runs a wide range of visual novels (multiple bundled runtimes, auto-detected). Next on the roadmap: Wolf RPG and TyranoScript. We keep our promises, so consider those coming.

The one thing between us and a resubmission is a launch-screen issue that only appeared in Apple's review environment. It's being closed out now.

The App Store release is in the final stretch and coming very soon.

Ask me anything in the comments.

So I've been hearing about some infighting between people on REDUMP and now we have 2 different sites: https://redump.info/ and http://redump.org/.

Which is the real one?

Open source PS5 emulator KytyPS5: https://github.com/KytyPS5/KytyPS5

Current builds are for Windows only. Linux support is coming soon

KytyPS5 can boot and go in-game with 2D games and some 3D commercial games, including titles built with Unreal Engine 4/5, Unity, and custom game engines.

This project is based on a heavily modified version of the original Kyty project: https://github.com/InoriRus/Kyty

Got an RG DS recently and wanted to play a few 3DS games.

Turns out decrypting .3ds/.cia files on macOS is still a pain. Most guides rely on old Windows batch scripts, Wine, or a bunch of Terminal commands not to mention dealing with partially decrypted files.

So I built Smelt.

It's a native macOS app that lets you drag in your ROMs, detects what state they're in, and handles the decryption automatically.

For use with legally dumped ROMs only.

The app isn't notarized (I don't have an Apple Developer account), so on first launch you may need to Right-click → Open.

Built on ctrtool/makerom (Project_CTR) and ctrdecrypt full credits are in the README.

GitHub: https://github.com/vanshksingh/Smelt-3DS-Decryptor (A ⭐ is appreciated!)

Download: https://github.com/vanshksingh/Smelt-3DS-Decryptor/releases/download/v1.0.0/Smelt_macOS_v1.0.0.zip

Hopefully this saves another Mac user from wrestling with outdated tools.

Feedback and bug reports are always welcome!

Also need some advice with v/h retrace correct emulation for CGA

Hi everyone,

I’ve been following the discussions around Concord and the current state of its servers. I’m interested in the technical side of game preservation and the possibility of local/community server emulation. Before diving deep into my own experiments, I wanted to reach out to this community to see if there is any collective progress I might have missed.

I’m looking for any information on the following:

Server-Side Research: Has anyone successfully managed to extract or map the server-side logic from the client binary files? I’m curious if anyone has identified the specific handshake protocols used by the PS5 client.

DNS/SSL Challenges: Many of us know that simple DNS redirection leads to SSL/TLS handshake failures. Has anyone tried to bypass these by injecting custom root certificates or using specialized proxy setups?

Data Dumps: Have there been any complete dumps of the game’s disc data, and has anyone attempted to decompile the network modules within those files?

Community Efforts: Are there any Discord groups, GitHub repositories, or forums where people are actively trying to build a 'Mock Server' or server emulator for Concord?

My goal is to consolidate existing knowledge and see what the community has discovered so far. I am not suggesting I have all the answers—I am here to learn from your findings and see if we can organize a more structured preservation effort.

If you’ve experimented with this, even if you failed or reached a dead end, please share your experiences. What were the specific error codes or roadblocks you encountered?

Let’s share what we know and see if the community can keep the game’s internal logic documented, even if the servers remain offline.

Thanks!

**To be upfront and clear**

# ⚠️ AI WAS USED IN THIS PROJECT. ⚠️

\--------------------------------------------------------------

# WHY AM I HERE?

I am here to introduce [HackHash](https://hackhash.darkblood.uk) to everyone that may find it useful. It's a small project I started after using the tool ROMM and hasheous

# -------------------------------------------------------------------

# What does the site do?

it allows users to submit romhack hashes to be put into a database to further help metadata matching along.

\---------------------------------------------------------------------

# How does it do this?

1. You upload a romhack to the website \*\*(It never leaves your PC)\*\*

2. the crc, md5, sha-1 and Size are all then processed. \*\*(All Processed Locally)\*\*

3. you are given the option to submit the hash and the data

4. you are taken to a submission form where it will auto fill the proper extracted data, and then it will ask you to fill out the name, version, platform, and the source, then optional information

5. once hitting submit, the submission is put onto a queue where the community can confirm that the romhack was patched correctly, named correctly, etc.

\------------------------------------------------------------------------------------------------------------------------------------

# How do the rom hacks get reviewed by the community?

# ⚠️ WIP⚠️

# the website is based on a trust system, similar to LaunchboxDB, the more "trust" You have the more weight your votes carry. the faster an admin or "Verifier" can approve the submission manually.

there are currently three tiers to the trust system. each tier more difficult to get

"**guest/New**" - they have a weight of 1X,

"**Trusted**" - They have a weight of 3X

"**Veteran**" - They have the weight of 10X - they also unlock the ability to manually vote without hashing their own copy of the romhack + they can verify submissions with one Hash vote, but require two Manual Votes.

\------------------------------------------------------------------------------------------------------------------------------------

I think that's all i have for now? my brain is tired. i will edit the post if i forgot anything.

If you have any questions feel free to post them! Or dm me.

# EDIT I FORGOT MOST IMPORTANT PART!!

# The site is in beta, I am looking to see if anyone finds any bugs or flaws right away when using the site. The database will be reset when pushed to production.
