- 0.31: John Butler fixed pixel doubled sprites in Exerion. Known issues: Sometimes the game resets while you are playing.
- 0.30: Brad Oliver added Exerion (Jaleco 1983). Exerion is a unique driver in that it has idiosyncracies that are straight out of Bizarro World. The background graphics are missing. Sometimes the game resets while you are playing. It has been reported that the original did it as well, but this is still uncertain. The mystery reads from $d802 - timer-based protection? The freakish graphics encoding scheme, which no other MAME-supported game uses. The sprite-ram, and all the funky parameters that go along with it. The unusual parallaxed background. Is it controlled by the 2nd CPU?
