My point was about the different ground location for the Arduino, which I copied and pasted right from the Arcade Hacker blog. One place says use CN7 A23/B23, the other says use CN2 C32. The photo is of my setup once I figured out the correct pins for my keypad/LCD shield.
Also worth noting...
I'm in the same boat. Got an AvPJ on a 93646B-3 board that was once working, but I can't get it to take a keyload.
I think the different pinout of the keypad/LCD shield is part of the issue.
My LCD keypad/shield is the Sainsmart one linked in the Arcade Hacker instructions, but the one shown...
Just a followup, as I got this thing running 100%. The ROM socket was just one of many problems here. The biggest culprit was that battery replacement that was done before I took possession of the board damaged the traces such that there is a broken connection somewhere on one of the inner...
Found a couple of things. Popping off the ROMs to install the multikit revealed a damaged socket, for ROM 19, pin 32. Secondly, I think my ROM burning woes are due to leaving EPROMs in the eraser for too long.
I'm going to give it a shot again, using the Euro ROMs, which seem to be the parent set for this game.
No suggestions on the read/write modes for the burner? Use defaults?
HAD a battery. That was removed when I tried the multikit. I'll put it back on and re-do the encryption key again once...
This is the only CPS2 board set I have at the moment, so no. Being the South America version of course also makes it more difficult to find another test candidate. I did discharge the caps near the battery.
I'm tempted to throw my multikit on it to try to isolate it to a board or ROM issue...
I am working on a DDSOM board set for a friend. It is a South America version. This was a board he got as part of a "mixed lot" of CPS2 boards. The board had the battery replaced before I got my hands on it, and it also looks like the jumpers were changed. I have never gotten anything out of...
