Hi Al82,
Regarding Midway MK games - due to some technical reasons, we have to leave the height at 256px. If sometime a workaround can be made, I'll let you know.
I'm not good at this game, so I need a little help here, if possible:
Regarding the test your might stage problem, the next time(s) you play this game, please make a savestate at the end of the level before it comes on, then if the background gets corrupted, please post the savestate. The savestate really has to be from before the bad background gets drawn.
best regards,
- dink
