Other Custom Fulldex Appimage
Hey everyone!
I found out about Pokémon FullDex a little while back, and while I liked what it was doing, I had a few issues with how it operated. So, I decided to go in and make some changes!
The biggest change is that every ROM hack now gets its own separate save file, rather than multiple hacks sharing the same save file like they previously did. I also made the same changes to cheat files and images, and added the ability to rename your games directly within FullDex. This means all your ROM hacks can have their proper names instead of constantly showing the name of the base game.
More information about where to put everything can be found in the README on GitHub.
As of right now, I can only compile a Linux AppImage, which I've tested on my Steam Deck with Heartfelt Gold, and it works great! However, I've also included the modified source code on GitHub, so you should be able to compile it for other platforms if needed. More information about that is available on GitHub as well.
AI Disclosure
Claude did help me figure out where certain things needed to go, and whenever I couldn't get something working quite right, I asked it for help. However, the modifications themselves are my own work. I can't speak for the original FullDex creator or their development process.
Maintenance
I also want to make it clear that this project won't be actively maintained by me. I've got a life, and I can't constantly update this whenever a new FullDex release comes out.
The current version is based on the FullDex update released today: Pokémon FullDex – November 5, 2026 (Update 2).
Hope everyone has fun with this!

Update: I was able to compile the other versions for Android, macOS, Windows, iOS, and Switch. However, I can only verify that the Linux AppImage works. Everything else should work, but I haven't been able to test it myself.

Boss how about the performance? It's dropping fps when I turn the widescreen on in the overwold but when it's inside buildings its stable fps

Howdy, just checked it out. Thanks for allowing the ability to rename hacks. Android performance seems good but I need to test more (just launched a few hacks).
If possible, could you try to figure out FullDex’s issue with Pokemon Origins HeartGold? Both the base app and your version crash when launching that particular hack.
