I know collectors will kill me for that question

The Multi Game PCB should be a simple Jamma print ready for my Egret2. I once had a “2xxx in-one” Bartop machine and it just sucked because the games didn't play like the originals. The games should really play and look like the originals, otherwise I won’t buy one of these.
Games I would like to play:
Donkey Kong
Space Invaders (or kind of these)
Pac Man
Bubble Bobble
Bomb Jack
Mario Bros
It’s not a disaster if not all games are supported. Most important is that they play and look like the original.
