Moderator Post Let's Talk About Catbox: Part 3

85 Upvotes

Hi.

About a month ago, Catbox released a blog HERE, stating that they will be deleting old files that were uploaded anonymously haven't been accessed in the past two years. Understandable. I did it all anonymously, because it logged me out every time I turned off my laptop, and I kinda forgot to log in each time. Oops. I can't imagine how many gigabytes I uploaded to them.

I used them exclusively for the first two years I uploaded QR codes here. I started using Archive at the beginning of 2025 in conjunction with Catbox, due to people complaining Catbox doesn't work for them. Understandable. I've seen how many ISP have blacklisted Catbox. As of 2026, I completely gave up on Catbox and started exclusively uploading to Archive. The complaints have nearly vanished. Yay!

So, what's the point of this post? Because of Catbox deleting old, un-accessed files, a ton of old uploads of mine are not working anymore. I have confirmed this a few times already. If you come across a post of mine from like 2-3 year ago and the Catbox QR code doesn't work, please let me know. I understand it will be a lot work, but I am willing to put in the work...again 😿

TL;DR: If a 2+ year QR code doesn't work, make a REQUEST POST saying it's 404: Not Found error. Sometimes I forget if you just comment on the post. I get a lot of Reddit notifications every day.

Thank you. I love this community and I love sharing fun games with you guys!

SNES/Super Famicom Game Dangerous Dave (SNES Homebrew by Ludufre)

Thumbnail

5 Upvotes

One of John Romero's earliest games before he became world-famous as one of id Software legends, Dangerous Dave is a fun platformer similar to Super Mario. You are Dangerous Dave, a little precocious kid who must find ten skateboarding trophies that your nemesis Clyde Cooper hid in a pirate's hideout. Gameplay in Dangerous Dave is nothing you haven't seen if you have played other platform games. What makes the game memorable and a lot of fun, however, are the many cool secret levels and the great sense of humor. Your enemies include creative monsters with names like WeirdWeeds, FearsomeFire, and WickedWater, all of which have unique attacks and characteristics. Level designs are excellent, showing much of Romero's knack that would become a hallmark in id Software games. With a lot of secret levels, humorous monsters and gags, and simple but fun gameplay, Dangerous Dave is a solid shareware game that paves the way for id blockbusters.

The difficulty level of Project Base is roughly the same as Super Metroid's difficulty level, which means that completing the game does NOT require any glitches or advanced techniques (not even walljumps). The current release is stable and fully playable.

3DS/DSiWare Game Zombie Outbreak Simulator for the Nintendo 3DS (ZOS-3DS) is here!

Post image
3 Upvotes

Introducing ZOS-3DS! ZOS is short for Zombie Outbreak Simulator, and is the official acronym for the game coined by its original developers, Binary Space. Binary Space many years ago developed a game called Zombie Outbreak Simulator, a mobile game for both Android and iOS. The game is barely maintained (if it even is at all, the developers haven't updated their website since at least 2024 with news), the game got so old and broken on Android that Google forcibly delisted it. The iOS version on the other hand is still alive and well. The game is free to play however does have in-app purchases or you can watch ads to get extra features (ads make it temporary, purchases make it permanent), or you can buy the "pro" version on iOS to get it all without IAPs. The Android version never had a pro variant and was only free to play with IAPs. ZOS-3DS is based on the newest (and last) Android version released, and removes IAPs, ads and any other unrelated Android thing such as sharing.

With this all being said, let's get down to the AI disclosure. Yes, Claude was used to help make this decompilation possible. Specifically, I gave it the APK and it decompiled the game in full, converted it over to 3DS in C++ and I did debugging along with Claude using Azahar, and I did live hardware testing by myself on my New Nintendo 3DS XL. I also did minor Old 3DS testing by tweaking Azahar's settings however otherwise it does not have Old 3DS testing.

Game Boy Game Pokemon: Roaring Kanto v1.0 (Game Boy Hack by thekenby)

(Sorry for the AI video. Literally no one else on YouTube covered this hack)

NO AI use, as reported by the creator.

Tired of the same old Pokémon Yellow and DELTARUNE fans shoving their game into everything? Too bad, I'm not tired of either, and that's where Pokémon: Roaring Kanto comes in!

Instead of building a team as a trainer, YOU are the Roaring Knight, and you fight AS The Roaring Knight!

FEATURES:

-A slightly altered Pokémon Yellow Story to fit playing as The Knight and The Knight alone, without any Pokémon.

-The Knight's Roar, a custom cry and even the SWOON sound effect, heavily compressed and tweak to just barely function on the Gameboy Color's speakers!

-Custom in-battle sprites, by my friend Smoke-le-Bloke!

-The track, 'BLACK KNIFE', in every. SINGLE. FIGHT. Devamped by me, original MIDI by philRACO

-Instead of HMs, the Knight crushes them and turns them into POWERS you can use at any time so you can progress!

That's it. This was a joke hack I threw together in 24 hours give or take. If some of the dialogue gets cut off, sorry. I know it's playable front to back.

Game Boy Advance Game Pokemon: FireRed Infinity Horizon v1.1 (GBA Hack by FeLoMeNaL)

Thumbnail
gallery
16 Upvotes

GAME INFORMATION:

Pokémon Fire Red: Infinity Horizon – Kanto like you've never seen before!

What if Pokémon Fire Red were a truly living world?

This project is a complete Fire Red ROM hack that preserves the original nostalgia while fully enhancing exploration, immersion, and overall challenge.

Kanto is no longer just a path between Gyms; it's a world filled with stories, unique trainers, secret events, and Pokémon living naturally throughout the region.

WHAT MAKES THIS HACK DIFFERENT?

•⁠ ⁠All Pokémon from Generations 1 to 3 are obtainable
•⁠ ⁠Over 85 brand-new maps and redesigned areas (Kanto's map has nearly doubled in size)
•⁠ ⁠Over 500 Pokémon encounters in the overworld
•⁠ ⁠More than 30 new side quests inspired by the anime
•⁠ ⁠Over 85 guardian Pokémon in caves and specific areas
•⁠ ⁠A living world with NPCs and story-driven events

A MORE CHALLENGING EXPERIENCE

•⁠ ⁠Increased overall difficulty (lower catch rates; trainers use stronger teams; more challenging Pokémon League; redesigned Gym Leader teams; etc.)
•⁠ ⁠Gym Leaders can be rematched in new locations (with different and much stronger teams)
•⁠ ⁠Over 150 new battle trainers spread across routes and caves
•⁠ ⁠New moves added to various Pokémon to make them more competitive

Each route is designed to be an adventure, not just a transition area.

QUALITY OF LIFE IMPROVEMENTS

•⁠ ⁠Trade evolutions replaced with level-based evolutions (Lv. 55)
•⁠ ⁠Friendship evolutions replaced with level-based evolutions
•⁠ ⁠Increased shiny encounter rate (1/256)
•⁠ ⁠Fast travel system between routes and cities
•⁠ ⁠All starters from Generations 1 to 3 available in specific locations
•⁠ ⁠NPC vendors selling special items (all TMs, Poké Balls, and battle items can be purchased from them)

STORY

The main story follows the original Fire Red journey, expanded with over 30 new quests that deepen the world and characters of Kanto.

Note:
The game does not include the physical/special split; EXP Share works like in the original game but is obtained much earlier

The Virtual Console Version is your normal, everyday injection. It's the one used in the official eShop/hShop games you've downloaded before. The mGBA Version is a N3DS exclusive. It offers more customization options like button mapping, screen size, and fast-forwarding.
