wellllll.nes injection works....but its a bit of a pain in the arse, you have to upload PRG and CHR separately into ram....even though there is another instance of the whole rom together in ram the one used by the system is split up
anyone wanting to have a go of it PRG is at 0x10BC83F0 and CHR is at 0x10DC83F0....this is where it is with zelda 2 anyway i dont have any other NES VC to see if its the same across all games, and i only tested snakes revenge as it also uses 128kb CHR&PRG.....i dont know if trying to inject bigger roms will work
ok tested a few more, zelda 1 worked, castlvania 2 worked,metroid works, smb 3 didn't (wasn't really expecting it to as it uses mmc3 mapper and is bigger than zelda 2)
