Still not working So I've been sent a ROM board with Rev. B of Sega Rally Championship, and it STILL doesn't produce sound effects. That said, I did find a different Sega Rally Championship board on eBay that has Rev. C ROMs on it and a PCB that I have no idea what it does between the ROM...

Well that explains a lot, my PCB didn't come with that extra board. I'm not even sure the seller is aware of this extra board's presence. I'll see if I can get one somewhere. Rev. B and Rev. C don't need this board?

I appear to have a revision of Sega Rally Championship where IC37 doesn't exist, at least according to MAME's source code. It would seem I have Rev. A of the game, one that is only for deluxe cabinets and has no link capabilities. The EPROM and Mask ROM numbers correspond to the srallycdx ROM...

I just received a Sega Rally Championship board that has an audio issue I can't seem to really understand why it's happening. The game has sound, but all that plays is music and speech. Any and all sound effects are completely silent and I am absolutely stumped as to what could cause that...

I would like to purchase your second After Burner II PCB.

Okay guys, I hate to bump this, but I've still got some weird things going on here with the Life Force board. By some miracle, I managed to repair all the damage that was done to the PCB and jumped a damaged pin on the 0005292. However, I still have two major issues: 1. The board keeps...

Looking to get a Konami Nemesis PCB, be it fully functional or with a fault on the top board. There must not be any faults on the bottom board; I've already had a Life Force board go up in smoke due to something going wrong on the bottom board and I don't want to have that same experience again.

Well, first thing I found was that the 68000 looked to have been behaving very oddly. Turns out it was not receiving a clock at I found a 74S74 in the clock circuit that was getting really hot really fast. I have since replaced it with a 74HCTLS74 and while that did resolve the clicking noise...

Need some assistance with a Life Force board that won't boot Just got a faulty Life Force board today that's giving me a bit of a hard time. Currently, the board does absolutely nothing. It sits at a black screen and I can hear some popping noises coming off the JAMMA harness' audio output (I...

I've never used the audio from the JAMMA connector on my iCade; always have the sound running off the 3.5mm jack through 11-year-old computer speakers or through my TV's audio inputs if ever I feel like using my iCade on a TV or to do direct capture off the PCB(VGA converted to S-Video with an...

If you still don't get VGA after setting DIP switch 2 ON before powering up the 60-in-1, yours has a defective VGA output. Either that or your monitors have problems with 640x480 resolution(640x480 is the resolution of the 60-in-1's VGA output), which I highly doubt. If your 60-in-1 has a...

Before we go any further, which version of the 60-in-1 do you have? The older models with the big socketed FPGA(?) and socketed EPROM, the later model with a soldered FPGA(with or without the plastic cover) and socketed EPROM or the newest reduced-size 60-in-1s with 2 soldered Flash ROMs? I...

What to try next is to actually enable the VGA output of the 60-in-1 by flipping DIP switch 2 to the ON position. You're not getting any video out of the VGA output because the board is set to output 15KHz RGB out of the JAMMA connector(DIP switch 2 OFF). First flip that DIP switch and then...

I just got a 60-in-1 PCB for the following reasons: 1) Evaluate how well it reproduces the included games 2) It cost as much as an arcade board with just one game on it($150 - this is a fixed price on all used PCBs locally) 3) I wanted something simple to use in a homemade cabinet(I know MAME...

That's the Bubble System/GX400 version. HOWEVER, the game selection screen and the instruction booklet shows a screenshot of the VS. System version, which is why I have absolutely no idea which version of Gradius is on the 19-in-1. The screenshot on Jammaboards.com shows the Bubble...
