A JAMMA adapter for a non-JAMMA game? Would Clay Cowgill's adapters work?
I support the decision to invalidate and take down the high score records (and apparently there is much schadenfreude to be had, from what I've been reading -- I haven't see King of Kong yet), but I can see where this can get ugly even for "authentic" DK cabs:
How do we know a DK cab wasn't JAMMA converted? How do we know all of the resistors and capacitors are working to the levels they've would've fresh from the factory? Is the high score "really" correct after potential bitrot/incorrect PSU/not enough voltage/the monitor wasn't from 1981/the ROMs have wrong stickers/Shigeru Miyamoto didn't bless it as genuine/The Ikegami conspiracy/... WHEELS WITHIN WHEELS MAN
...anyhoo, while MAME and other emulators shouldn't be used as a gauge for human, non-TA speed/highscore runs by this type of standard, this can open the door for all sorts of high scores to be potentially challenged.
Just make a separate highscore board for emulators and ones for the "actual" hardware and be done with it.
Don't make me go Hyper on you.
