Hey!
I have a nice looking mv1b that outputs no sound, only a buzz when making the volume high.. and it also reports M1 rom error in the beggining of the boot.. tried a couple of legit games that works in my mv1c, they all report m1 rom error..
then I found some info somewhere (lost the link) about that the MV1B needs the bios changed to work?? I have a spare neobiosmasta for mv1b/c.. I understand that there are 2 versions of the mv1b board, one for irritating maze only, and one regular. how can i see wich i got?
the bios have SP-3 on it, and the silkscreen under the pcb says:
NEO-MVH MV1B
1996.1.19
any thoughts?
