A Brook UFB for that whole cab? You've got yourself a deal. :P
In all seriousness, though, you're making me consider dropping the cash on this one. I'd LOVE a CRT cab just for the ease of connecting JAMMA boards.
I have like 4 or 5 completely built boards where I was trying to diagnose an issue thought to be with me building them. Turns out, my dumb ass forgot to turn on the +5V switch on the Jammafier. :facepalm: They're all fine, I'm just a blind idiot.
If you want one, you can have one. Just cover...
I think it's Ver.2012 that has 2P mode? I'd have to fire my system up and check. As for FastIO on TGM3, I have no idea and I can't test because I don't have a FastIO. :(
TGM3 has a separate disk image. You'll need to swap between them because of driver incompatibilities. I think SSFIV's 2P mode is a test mode setting. SFIV might be the same, but I've never tried. I know USFIV is 2P, since that's the only version I play these days.
Tetris drive image is here...
Or Guilty Gear on the Naomi. For some reason, it defaults to the following:
K S H
P D X
When the default layout SHOULD be:
K S H
P X D
Yeah, there's a thing in the test menu to fix it, but you have to do it every time you switch games.
