I have set my MK3 to skip the rom check, but can't find a way to do it w/ MK2. No dips or menu settings? I thought it was possible because a few folks have all the MK's in one cab and I though I saw that they turned off the boot up menu on youtube. Thanks for any advice.

Hmm the manual doesn't show a dip setting for it, but in MAME it does. I just tried it in MAME and you can change the setting there.
 
Got that part, just trying to get the board to not perform it at all. I have a Jam TE and it has the option, 2 on 2 open Ice does, MK3 does, but can't find info on MK2. Sux. I thought when zenomorph did his multil that he had all his boards skipping the test.
 
hope this helps. ;)

all the Williams/Midway games have a Dipswitch Test (much like the Switch Test) where it'll show you which dipswitches are on and what the functions are.

I never noticed how stupid that dipswitch table was in the manual. it's good for the dipswitch coinage settings by region -- that's about it. LOL

zenomorph if I'm not mistaken (watched all his videos on the switcher when I was setting my 6-in-1 up) left the powerup tests ON so that he could see if any of his roms were bad. he had some MK3 boards that roms would fail on in a couple vids, I can understand holding start, but I can also understand why you'd want to skip it. I run my MK boards in an arcade, so I leave the POST on.

Got that taken care of. Thanks for the info. Oddly enough, by 1/2 Circuit board dip was set to 2 boards, but I have the version where the expansion is not needed and it never tried to check those roms.
 
well maybe we've uncovered that mystery. there's been another thread on here lately about a 4 -> 8 mb rom conversion that won't work.

perhaps that dipswitch just activates the expansion slots. the game most likely does the rom check on the main board first, but since all your roms are good, it'll pass the rom test. if it were the other way around, where you'd need the expansion, the rom test would fail, because it's missing half the roms, because the expansion isn't active via dipswitch.

useless knowledge time:
apparently there were only a handful of games based on the T-unit. I forgot that the Wolf unit was introduced not that long afterward, only the NBA Jam games and MK1 and MK2 and I think one other game used the T-unit. for the hell of it I was playing NBA Jam the other night and observed that the dipswitch for the expansion board isn't even present in that game, but it's probably because that came out before MK2. MK2 might be the only one that used the expansion...

guess the guy with the 8 mb rom conversion has a rom or two wrong. the information on the video rom locations is probably inside the 2 game roms right?
