I also noticed that this (new) interface shows the available game systems it can emulate out of the box if you select "Show only available". However, that list is so long compared the the games/roms that I own that its a bit confusing...
By the way, its also a bit hard to figure out how the new interface works because the official Wiki
has no text about it (yet). All "unofficial" websites have obsolete info 'bout Mame's UI.
Keep up the good work on emulating the only game systems I still play on!
