I am probably a bit of an outlier for this group as I use OPEN EMU for the Apple Mac platform to run my 5200 games if I don't get around to playing games on my actual console. I had to use my emulator here as my 5200 flashcart died and I have no other physical cart set up to play Jumpman. I ran into the same problems with Jumpman on OPEN EMU as some of those using Altrira - upon starting the game, it makes it to the game demo screen but none of the controls work (whether I run it from a keyboard controller or a steel series nimbus). I tried a few other 5200 game roms and they seemed to work fine, so it must be some sort of emulator (BIOS?) issue for me as well. See you next round.
