Ah, I see. I think I understand! I downloaded the full .213 ROM set from a certain members only site. I was under the impression that some games needed a BIOS ROM; I'm yet to encounter a game that doesn't work yet so I'm probably okay. Thanks for replying!

I'm pretty new to all this (well, not used MAME for well over a decade!) Here's what I've got: LaunchBox 10.1.0.0 MAME (64 bit) 0.213 All ROMS including CHDs (all merged) 0.213 All BIOS 0.213 All is working perfectly fine...except I have no idea where to but the BIOS files and how to configure LaunchBox / MAME with them. I have searched but was somewhat overwhelmed with the results and could do with some help - and as simple as possible please! Sorry if it's been documented here already but I couldn't find anything that helps.
