@drubzyy I verified your run and I saw you used a mobile rom, Which rom is it? I am curious to use it because I also want to run this game.

I can't speak for drubzyy per se, but the ROM he used for his Petscop !! run is almost certainly identical to the "original" version of the game you can use on any other NES emulator. It's not like ROMs are made specifically for mobile emulators or anything. Also, I'm pretty sure he used Nostalgia NES as his emulator, but I think you already knew that.

Hey! Dlloy I used nostalgia.nes PRO but there is also a lite since the pro cost money
