It was noticed before. I have a conversation thread between you, me and Apocalypse in November of 2020 discussing this exact issue. Either way, I'm glad it's been fixed. I'll do the mod on my PCB and send you a message for the new GAL code. Thanks!

I've converted a Model 3 Step 1.0 and a Model 3 Step 1.5 and can confirm that for those to revisions the PALs are the same. I didn't have to move any of the jumpers on either conversion (Get Bass -> Virtua Fighter 3 TB and Virtua Striker 2 Ver. 98 -> Le Mans 24). The speed of your EPROMs match...

If this still isn't fixed, I have the correct jumper settings for you. The only one I notice from your final setup is JP20. It should be on 1-2 instead of 2-3 as you have it in your pictures that were posted on Feb. 9th. I believe there is a load time on the character select, but I haven't...

You would also need to design a multi I/O board. The little board near the front of the PCB, to the side of the JAMMA connector, comes in at least two different types. There is one for the standard fighting games and a different one for the racing games. If there is going to be a multi, it...

It has been running without error for about 8 hours now. I've coined it up to max credits (9) and played 2 player games with my son for about half an hour. He has played it all the way though with Goku and finished it in about 35 credits. We finally had to look up the character cards online...

I've got to go to my niece's birthday party in about 30 mins, but I've burned a replacement and given it a quick test. The game will boot with the standard territory warning if the FD1149 is present on the board, but then just goes to a black screen. If the FD1149 is removed the game boots and...

Give me about half an hour. I'll test it out. Thanks Asure, you're awesome!

I was thinking, more specifically, of Dragonball Z V.R.V.S. and Dark Edge. I have a dead ROM board for both of those games. Interestingly, they *will* boot. I get the region warning and then just a black screen (if I leave the security module in place) or a black screen that flashes "Insert...

Any thoughts on removing the security from the other System 32 games that have it?
