Yes, those game are quite heavy for the Wii to handle.hey there, i' am trying again to get nba hangtime / nba blitz working (lost my original wii sd card), but based on previous posts (some i made), it looks like some midway games just won't run well, and some don't work at all on the newest mame2003+ cores? thanks.
The closest you can get them running is at around 12fps.
