Yeah I'd love to see marbleman too. Good luck. The few owners are holding onto the boards for dear life. They spout off that it took them forever to get the games and they're not releasing them for any price, blah blah. Dumping the roms wouldn't change the fact that you're STILL one of TWO owners of real marble man cabinets, any more than the fact that Pacman/MsPacman are dumped make your real, dedicated, mint condition Pac/MsPac cabinet worth any less. It would only allow more people to experience a game that, although was anticipated, was never released. They're playing the "I'm cooler than you" card. It's lame. But it's human nature, unfortunately.
Note: I am not a mame dev.... but.....:
The hardware for golden tee is Already Emulated (itech32.c in mame). The games aren't being released for emulation, basically (as far as I can tell) to preserve MAME. Incredible Technologies is one of the, if not THE Most profitable arcade companies in existance today. And they're NOT someone you want going after MAME... Period. They still make money off of them.. And EVEN THOUGH by next year (2005), mame's so called "5 year rule" will be up for all the GT3dgolf - Golden Tee 2k games, don't hold your breath about a rom release.
Simpsons Bowling would be cool to see too. Problem is, there's really not that much out there left to emulate. :-/ And I don't really care about CPS3, because there's only so much I can take of "5,287,2425 hit super duper team play combo!!!" Random button bashing is much less fun for me..
