Finally trying out the Romance Of The Three Kingdoms 2 board i socketed quite a while ago, I noticed binaries above 32 bytes wouldn't work with my EPROM emulator. I can only conclude that the PRG-ROM is not consistent with the other ones used on NES boards. I suspected that upon socketing I already noticed that the CHR-ROM seemed inconsistent.

So is there anyone out there who has made an MMC5 devcart (or even used the exact same board?) and could tell me the differences in the pinouts? Since I've already socketed the board, I'm not too keen on tracing it myself...
