Is it worth trying to repair this cart or should I just buy another if I can find one? Retro arcade PCBs can take 5.4 for a good amount of time no problem and even higher for a little while but if these buffers die at 5.1 it makes me wonder how much of the rest of the board on these, which sure, may survive 5.1, still blows up super prematurely and quickly at 5.2. That was with the Naomi unplugged and at the supply so we can probably assume the Naomi was getting 5.3-5.4 downstream and under load. and then after that all there seems to be to do is replace the cart, all surface-mount stuff.Īlso, when I measured the 5v line before putting in my working Naomi it was at 5.6 from the previous owner. I think my next step is verifying the data on that big socketed through-hole chip. All the pins in the tan connectors that go into the NAOMI are intact and look okay.

I reseated the cart a bunch of times, reseated the big chip some more, tried it with the game case off to make sure it was going in all the way, and even swapped the big chips on the board (same number but one had a D after it) and even the little serial number chip but no change beside that one time. Voltage is fine, I adjusted it before putting the precious new NAOMI in but it looks like it was way too high at one point so maybe that fried the game cart and the old NAOMI. The NAOMI was working in a different game just two weeks ago and tests out okay so that is NOT the problem. Any time it has said "ROYAL RUROYAL RU" the game will go to no signal if I try to enter the game's test menu, and will crash on the NAOMI test menu screen if I try to run the ROM board test for the game. I noticed when it worked that one time it correctly said "ROYAL RUMBLE" as the game name in the NAOMI test menu, but all other times it has said "ROYAL RUROYAL RU" as the game name.
I went back to boot the game and nothing. I reseated the one socketed chip on the game board and at one point I got the error 02 to go away and got a different error number there, an error that the settings were wrong in the game adjustments, which looked promising, so I went into the NAOMI test and it actually let me into the game adjustments to reset the adjustments (which seemed to be default already, so) and I cleared the backup data as well in that menu. This is supposedly what happens when you mix BIOS regions but the WWF game only came in one version I believe, US, and my Naomi board came out of an American Big Rig Trucking (or whatever it's called) game, so should be all good there. It works 100% perfectly so obviously it cleared that error 03 right up but now I am getting an error 02, which is a game issue. It had a bad Naomi in it (error 03) so I swapped it with a working one I had sitting on a shelf I never knew if I was going to ever use.
