Tried asking on nesdev, and on fceux tsavideos, github, but no one is willing to help. I'm working on another multicart idea using mapper 209. The problem is, is that the mapper does not allow usage of WRAM/PRG-RAM. The mapper only let's you swap 8kb chunks into it as PRG-ROM. I've made sure my NES 2.0 header is correct for PRG-RAM usage, but I still get an open bus through $6000-$7FFF (everything remains 00's through it all)

I downloaded the latest source code to fceux, and tried to view the mapper file, but I cant understand c, or whatever variant of c is being used.

Anyone familiar with c, or know someone that would be willing to assist me in getting wram working for mapper 209?

Thanks! :-)

Can you publish your C code or sources online so nesdevelopment and board2 can see what they are dealing with ?
