Agreed about the name, but I think he renamed to TigerArcade (MAME), so people would relate more to what it plays. It really should have been called TigerRaine or TigerFinalBurn, since those are the rom sets it works best with.
MAME rom sets are moving targets to work, due to platform updates of the MAME app.
This app is better for just emulating what it does, since that is why it plays EVERY rom full speed with sound, even on the Incredible. Far less overhead than MAME, since only supporting a few platforms.
There are/were a few that played some, but not all of MAME4All rom sets (played about half). Jironi Arcade is the name and is still in market, but has issues with Gingerbread (the dev knows and is working on it).
