I'm familiar with retroarch and I use dig as a front-end on other devices. I'm new to launch box and pc emulation. I set retroarch as the default for launchbox. For snes and Nes launchbox knows nestopia and the correct snes core but for mame it doesn't. I have to right click load in retroarch download the core ex:mame-2003 then run the game manually through retroarch each time. I've watched eta prime and bits bytes videos on importing full rom sets and I think I found where to look but I don't know how or where I extract the large bittorrent that's where I'm lost. I know how to emulate basic zip files and haven't even tried to play any games with BIOS files. I just need help with a basic mame arcade game list.
