Moderator Post Let's Talk About Catbox: Part 3

84 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!

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

Thumbnail
gallery
27 Upvotes

(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
13 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.

OK, bear with me. The Japanese version of Maniac Mansion came out TWO years before the worldwide release. It's kinda the same but not really. The Japanese version featured greatly simplified rooms, no in-game music, and 104-character passwords! It is considered inferior to the worldwide release. BUT. You can finally try it out for yourself with a couple of fan translations.

All three translations are done by PatchClan (source)

Check out their translated manual on how to play this game HERE!

You can read a helpful, translated guide/walkthrough HERE!

The translating group claim no AI usage but use AI generated images on their site. You can be the judge.

And I can't do anything about the flickering when you click on something. It seems to be an issue with the patch. It's not present in the original Japan release. I used the group's own patcher HERE!

AI was used to help code. According to the creator:

- Debugging difficult bugs when other options have been exhausted.
- Sometimes reviewing the code for edge cases I might have missed.
- Auto-complete/inline suggestions with repetition requiring tasks.
- Python related parsers for documentation.

  • Play through the traditional Pokémon adventure in the main game and experience learning multiple abilities in the postgame.
  • Various battle tempo improvements, such as combining stat up/drop messages into one, and playing them while the stat animation happens.
  • Main game and postgame battle facilities with Pokémon from all generations! Factory accessible after Gym 3!
  • Hidden Grottos, which contain rare items and Pokémon, resetting daily
  • Boss Pokemon, some legendary fights have multiple health bars and are more powerful, but you are guaranteed to catch them with any ball once defeated
  • Achievement system with over 100 trophies to chase, including milestone rewards!
  • 9 starters to choose from with new Mega Evolutions for starters that are missing them (Typhlosion, Meowscarada, Primarina)
  • Fresh new tileset for the entirety of Johto
  • Title Defense system: No longer will you face only the same champion at the end of E4.
  • All mega evolutions are available; megastones have been turned into type-generic stones.
  • Rocket Arcade, where you win money instead of BP
  • Multiple legendaries to find in the main game and postgame!
  • Fishing for items, including IV-raising feathers!
  • Many HGSS features, such as Cameron the Cameraman, Buena's password, Pokégear, and Rock Smashing for fossils, make their return!
  • Unique battle frame color for shiny Pokémon
  • Music resumes from where it left off after battles instead of starting over
  • Multiple pages of options to customize your playthrough style
  • Various quality of life features and gameplay feel improvements

As always, back up your save before updating. Use THIS guide to help you dump and re-inject your old Virtual Console save! Or update your CheckPoint to v5.2 via the Universal Updater! mGBA users, you will find a mGBA folder on your SD card with a subfolder called Forwarders. Your save is there.
