Everdrive n8 pro and 64 banks with mapper 2

Post by avicr »

Hi, does anyone know if the everdrive n8 pro can run ROMS that utilize more than 16 banks of PRG with mapper 2? I've adapted code from a PCM demo (https://github.com/davidfigaromacintosh ... master/src) and both the original demo and my code run fine in emulators, but when deployed to the everdrive pro there is no video or audio output. If I modify the code to use only 16 banks (and include a much smaller PCM sample), then the everdrive runs the ROM as expected.

Is there an incompatibility with the everdrive n8 pro and ROMS that use large numbers of banks, or am I missing something?

Hey changing the header to be mapper 30 and declaring 32 banks of PRG worked great, thanks! Now I can move on to coding up sending a sample from the computer via the everdrive's USB interface to be played on the NES.
