Hello,i downloaded 2 hockey roms named:Mario Lemieux Hockey (MAME)Wayne Gretzky's 3D Hockey (MAME)
FBA supports the SEGA Genesis/MegaDrive versions (as you can see in the "game info box") and not the arcade (coin-op) versions!
My bad, I always forget we have Megadrive support. I honestly don't use it.
Genesis/Megadrive Mario Lemieux Hockey should be pretty much the same as the arcade version (SEGA Mega-Tech hardware), while Genesis/MegaDrive Wayne Gretzky's 3D Hockey is a "very reduced porting" of the arcade version (Atari Phoenix 3Dfx hardware).
Lol "very reduced porting" is a massive understatement.
