I recently picked up a ROUGH Irem Skins Game (from the roms, it's Set 2 in MAME) M92 board. This is the US version of Major Title II. Eventually I'm going to do a conversion on it, but I want to get it up to speed first. Some small, fuzzy mammal definitely made a home in between the two board...

I have a T-Unit (NBA Jam) that I'm trying to fix up. After swapping in known good ROMs, PALs, CPU, and FPGA chip I got it to boot but the graphics are fuzzy/crunchy looking. It looks like a RAM issue to me from other boards I've dealt with RAM issues on, but I'm pretty sure the video DRAM is not...

So I popped open my Japan-region Bubble Memories cartridge and got a bit of a surprise: The cartridge always struck me as a bit weird as the label on top is too wide for the plastic indentation. I was expecting a more traditional board layout, but this thing looks to be all 27C4001 512kb...

This is probably a very ignorant and uniformed set of questions so my apologies up front. However, I'm going to be attempting some Taito F3 cartridge conversions and I'm not sure if I'm going to need to create D77-14 and D77-15 ICs for mapping of the various ROM sizes, but in the event that I...

I have an Atari Dig Dug board that's a bit rusty and crusty. The PCB looks fine but a lot of the DIP chips have corroded pins. When I initially got it, it wouldn't boot. I've slowly been getting it back to operational order, but my troubleshooting skills are limited. All of my ROM chips should...

Picked up a MK II PCB knowing it was broken as something to provide a challenge to learn how to troubleshoot a jamma pcb. Was it a smart move? Probably not, but hopefully I can still make it into a good learning experience. I do not yet have an oscilloscope, so I haven't done any testing of...

I recently completed a Pang!3 conversion to Final Fight. After working around issues caused by myself, it's running great. However, it highlighted an issue with my long A Board that I'm not sure where to start troubleshooting. I also have a CPS Dash board for my SFII CE. I'm not seeing the...

I see the other WWF Wrestlefest thread below, so if this post needs integrated into that post, please do so. I just didn't want to hijack someone else's thread. So I had a working WWF Wrestlefest, but the audio had a horribly annoying buzz (Interestingly enough, I picked up another one for a...

I'm trying to troubleshoot a Street Fighter II CE board. I pulled and dumped all of the roms on the B board and they match the parent MAME set (with some minor variation in ROM naming like roms #'s being swapped???). However, I'm not familiar with the bodge wire C-Board modification. I've seen...
