Yeah i was playing some samsho5 special, Messed around with some of the codes and got a ram error. Turned off all codes and reset the rom, still had the same black screen with a ram error. Exited the rom, played samsho4 with no problems then tryed samsho5sp again. It worked but some of the graphics where screwy. Reset my box, booted up fba and everything worked like a charm. *Edit: Hmm.... it seems that my mamedox can now see and load the new roms (mslug4,5 samsho5 ect)... but they dont run. it lists them correctly and and knows whats supposed to be in the zip... but how ?
