I want to build a mame cabinet for my military heritage room / break room. I figured i would start with the actual comp and software and get it up and running first. I downloaded MAMEUIFX64 and have downloaded mame rom sets 0.161 and all the updates up to 0.170. I cant seem to understand what do next. I have followed the youtube video on downloading and putting everything in the rom folder but when i open MAMEUIFX64 and audit i still get only 3 green games to work. all the others are showing a grey chip. I feel completely lost and unsure of how to procede. Thanks for all the time and help.
