Hi,
Since I'm not experienced with coding, wondering if it could be possible to add PRG-A19 to this mapper?
https://github.com/ClusterM/nes_mappers ... C3)/MMC3.v
I already understand an additionnal register would be required for:
output reg [18:12] cpu_addr_out ==> output reg [19:12] cpu_addr_out,
Its the banking part of the code I'd like help with:Thank you.
