can i use android nostalgia.gbc? he uses practically 100% of the last gambattle from what I saw he doesn't print

no

@PinkishPrincess can I use https://www.emulatorgames.net/roms/gameboy-color/pokemon-red-version/

The only emulator allowed for runs is the Gambatte emulator, the directions to install it are in the category rules, along with this link to it. Feel free to ask in the discord about help setting it up. https://github.com/pokemon-speedrunning/gambatte-speedrun/releases

As a general rule, please don't ask for roms here. Valid roms will display <PSR> at the top of gambatte.

and a pity that does not have a port of the gambatte for android :(i don't have pc
