No.15314 B2K24 Senior Tester Aug 7, 2018, 04:05	Thanks. I'll attempt to figure this out. The save state won't load for me because it complains about invalid header. I'll have to play the game and make my own manually.
No.15325 B2K24 Senior Tester Aug 11, 2018, 08:13	I'm unable to see or hear that anything is wrong with the game that greatly differs from the video. Does anyone else have input on this?

I also noted that the in-game timer runs down too quickly in MAME. I tried changing the timer speed dipswitch from 'normal' to 'slow', but then it ran far too slowly.
