Beta: 3DS support is new, so expect rough edges and back up your saves.
Builds Pokémon Omega Ruby and Alpha Sapphire for your phone and your Switch, on your Windows PC, from your own game dump. Nothing from the games is included: you supply game.3ds.
Android (about 3 minutes)
- Unzip, put your game.3ds next to the .bat files.
- Run "Build for Android.bat". It makes the game code (000400000011C400.so for Omega Ruby, 000400000011C500.so for Alpha Sapphire).
- Copy it to your phone, then in FullDex open the game's menu and choose Use Game Code From PC.
The app can also build on the phone itself, but that takes about 25 minutes and makes the phone hot, so the PC is recommended.
Switch (about 4 minutes)
- Put your game.3ds next to the .bat files.
- Run "Build for Switch.bat". It makes a folder (omega-nx or pokemon-alpha-sapphire) with the game and its shaders, made from your dump.
- Copy that folder into /switch/ on your SD card and put your game.3ds in it. FullDex lists it in its 3DS tab and starts it, or start it from the homebrew menu.
A few shaders only appear while you play; the Switch saves them in data\dksh\missing. Copy that folder back next to the .bat (as "missing") and run it again to add them.
Windows needs no builder: FullDex for Windows builds the game's code the first time you choose it.
