Tried them all. 2010 seems unusable for the ~10 games I tried. Too slow. These are games that are also too slow/aren’t in FBA.
2003 gave me better results with those same games. Most we’re fully playable. I’ll have to get compatible romsets for those that didn’t load. Some needed to be dropped to 640×480 for speed. Overall not bad. It’ll replace advmame for me. I do wish Ninja Warriors was playable at 1080P :(
On a Pi2.

Some of the games I tried:
1080P: Some with minor slowdowns here and there.
Battletoads
Cadash
Captain America and the Avengers
GIjoe
Robocop
Mystic Warriors

480p: Some with minor slowdowns here and there.
Bucky O Hare
SmashTV
Ninja Warriors (not stretched)
