Thanks everyone.

MK2 indeed worked better in lr-mame2010. Not quite as smooth as 2003 or 2016 with sound sync off (only noticable on the scrolling "tree" fighter lineup and the "insert coin to continue" slide-in... actual gameplay is great).

NBA Jam TE worked perfect in 2010.

@whitesimo honestly you should get the romsets for lr-mame2003 or advmame and use those.

@brad2600 im not sure if it is playable. I havent found a working rom either.

I believe all the mame emulators will play these 2, so the answer above applies

@edmaul69 I apologize. I should've made clear the platform I was referring to in my first post. I've edited the post to reflect that.
