can you check if the nostalgia.gbc emulator uses the same engine as the android gambettan can be used? it is from android because i can't buy a pc i really want to speed up gbc games i would be very happy if you do this favor 🙂

Emulation allowed using the following emulators only: BGB, Gambatte-speedrun and Bizhawk

Any emulators not on that list are unverified and we cannot attest to their accuracy. If you decide to submit any runs using that emulator, we will have to reject them unless the emulation accuracy can be verified.

and how can accuracy be checked?
