Ah now there's something I can check! "Thou shalt check voltages," how could I forget? Thanks. Could it be that the NAC's PSU is going and it can't handle the extra draw of the CD-ROM? I don't have another CPS3 cart to test with and I don't know anyone that does. In fact, other than a buddy...

Haha, man, guess what I used? The gold was reflecting all across the ceiling when I was done.

I got a Third Strike board for a good price (by today's standards). Listed as "untested", I hoped that it was just a dead cart. Well after finally sorting out flashing the super bios (bad 29F400 apparenty), I soldered it back onto the cart and I still have a black screen. More of a very dark...

Duuuude! Darksoft was right, of course. Replacement chip worked just fine. Literally just selected the IC, loaded the file and pressed program (after a blank check of course). Now to find a CD-R lmao!

Interesting, I thought it did because it's given me warnings about it in the past, but I just shorted pins 1 and 2 on the adapter to test it. Nothing came up when I read it, it took 60 seconds to erase (where it usually takes 8 seconds) and it didn't actually erase since failed a blank check...

Thanks, but unfortunately, no there is no ability to set retries. The TL866 is a good little programmer, from my understanding, the interface seems simple though and doesn't have many options. I also updated the software and firmware, hoping that might help. Also, the that 16Mb chip I mentioned...

Ok, I'll try it tonight and report back. Dzięki.

I see. The only other TSOP48 I've got right now is a 16M. Think I should just concatenate the bios four times and try that?

Anyone have any tips on actually flashing the bios? I've flashed a few EPROMs here and there without issue using my Minipro TL866. I can read and erase the 29f400 fine. I was even seemingly able to rewrite the original bios, but I'm getting an error whenever I try to write the super bios...

It's nice to find a place with so many like-minded people, who want to play original arcade hardware and aren't afraid to fuck around with it to do so. Thanks DarkSoft. Polak potrafi huh? ;) I'm (very very) slowly getting into electronics for a hobby and got the idea a few months ago to try and...
