I have the nss (nintendo super system) bios in the main mame/roms directory.
when running mame/snes from command line it loads up, but I don't actually know how to load a rom. So when exiting, I get the following:
m50458-001sp ROM NEEDS REDUMP
m50458_char.bin ROM NEEDS REDUMP
WARNING: the machine might not run correctly.
Also have the master system bios in the main mame/roms directory.
when running mame/sms from the command line, I get nothing but the following error:
mpr-12808.ic2 NOT FOUND (tried in sms sms)
FATALERROR: Required files are missing, the machine cannot be run.
log file attached.
