    Irem Red Alert Help - Need Pics of Bottom Board

    Anyone have a Red Alert PCB that could take a picture of the top side of the main bottom PCB?

    Ghostbusters Repair Log , PCB Info and Gondomania Interchangeability

    Ok, not really a full repair log, but… I’ve been working on a Data East The Real Ghostbusters pcb for a client who has been very patient. The symptoms were a screwed up title screen, and lots of messed up sprites (background tiles were OK). I narrowed the problem down to a surface mount chip...

    Irem GDI Red Alert rom size?

    Working on a Red Alert board set that won’t boot or go into test mode, just garbage on screen. I have clock and reset, but the address lines on the 6502 are totally dead, and IRQ is sitting low. The 4116 ram have proper voltage. I tried reading the program roms but none seem to be verifying...

    Konami Jungler Help - PCB Pics?

    I am working on repairing a rough PCB marked as Konami Jungler, very similar to Locomotion but with some extra chips added in spots that are empty on Locomotion. I suspect I am working on an attempted Locomotion to Jungler PCB conversion. The game boots with sounds but all the graphics are...

    Gryzor/Contra Bootleg Rom 4/14

    Am working on a Gryzor bootleg pcb, and finally got it almost 100%. The last issue is the text that displays Continue and the Countdown timer is wrong. I read all the roms and the only one that didn’t verify was the one silk screened “4”. Since “5” and “3” verified as 15 and 13 from MAME...

    Working on a Caveman Ninja board with graphics issues, and wanted to verify the mask roms. Does anyone know what kind they are and what setting to use on GQ-4X? They are 40 pin, and the board is labelled 4M under some sockets, and 4M/8M on others. This board is similar to Mutant Fighter and...

    SNK HAL 21 Game Pinout

    I made a custom adapter to test an SNK HAL 21 PCB. It is an odd ball, non-conforming to any of the other common SNK pinouts (Rockola or Ikari Warriors style). I had to figure out the pinout myself since there is no manual online and nowhere else seems to have it documented. There are a couple...

    Separating board stacks for troubleshooting tip - ribbon cable shielding

    I recently found a solution to making longer ribbon cables work to help separate board stacks. I was working on several Marvin’s Maze sets with issues. This is a 3 board pcb stack where the boards are connected with several 60 pin IDC box headers (same as ribbon cables use basically). In order...

    Capcom Commando Repair Log - Scratchy and Missing Audio

    Just finished up a repair of a Capcom Commando pcb. This board worked fine except for audio. The audio was crackly/scratchy, and it sounded like a channel was missing. I noticed an M5224P (fujitsu LM324 equivalent) on this board, so my first thought was to just swap that. I desoldered the chip...

    Black Tiger missing 6K D8751H MCU/EPROM

    I have a Black Tiger that is missing the Intel 8751 MCU at 6K. I was wondering - is there a rom set that eliminates the protection this chip applies? If not, does anyone know what burners/adapters can burn the 8751 eprom data? I have a GQ-4X but it only shows 87C51 as an option with an...
