Thank you so much for decoding it. I didn't really think about it being HEX as opposed to binary, that does explain why it worked differently.
Which of the programs worked to decode it? I'm kind of curious if the full menu can run on standard Genesis hardware, it might be worth putting the entire dump in there (it has lots of unused data etc., including unused [
pirated] games and testing programs)
The Basic Fun arcades are a bizarre mixture of different hardware types; some are NES-based, some Sunplus, and a large majority are just handheld LCD fare (some even in black and white). Fix it Felix is one of the Sunplus types, I believe David Haywood has been working on emulating those (

think the Oregon Trail...
Edit: oddly testing it out further, the game seems to have considerable slowdown for some reason...I tried four different emulators, all with the same result. I wonder if it's expecting more power than a standard Genesis can output or something? I can't imagine it being due to the decoding process, it seems like it has issues at a hardware level
