    Atari's Garfield Arcade Game ROMS

    They will want a high res photo of the game PCB if you can. If you need help, I can submit the file to one I've submitted things to in the past that lives in Italy with your info as the submitter.

    National Videogame Museum

    ROFL! If y'all come in from out of town, give me a shout. I do repairs and have donated a lot of items over the years to the museum. It's nice to see some of those items on display and play on the gear I've repaired. :) The founders are great guys and the museum is plugged into the local...

    Welcome! Texas is a big place. There are FB groups for Dallas, Houston, and Austin/San Antonio. There's also a huge retrocomputer community in the Dallas and Austin areas. Where in Texas are you? I'm in the Dallas Metromess.

    Who repairs Atari Games Area 51 Maximum Force PCBs?

    For graphic corruption, Op will need to reflow the 2 Jaguar chipset chips - Tom and Jerry. If parts of RAM are missing from the memory map you'll get corruption, but it's on specific graphic elements, not across the whole screen. There are built-in self tests if they believe there are RAM...

    Galaga troubles...

    02xx or the color PROM. Never touch the 05xx. Legs are too fragile to f*** with.

    Blue Screen Capcom CPS2 Phoenix'ed Board

    I just tack it across the joint on the bottom of the PCB. Anything from 1K to 10K should work. Mecha: It's not that it comes back, it's that the table gets in a corrupted state.

    Mk4 Pcb problem- Help!

    I recommend you ask over on the Arcade Otaku forum. Lots of Europeans over there. I've fixed a few of those MK4 boards, but with the current tariff situation, I'm not doing international repairs.

    Mortal Kombat II Sound Issues - Dying Amp?

    Is the speaker wired to 10 and L on the edge connector or is one side of the speaker connected to ground? You cannot ground one side of the speaker on that game.

    Blue Screen Capcom CPS2 Phoenix'ed Board

    There's a cap labeled CC1 by where the battery goes on the CPS2 cart PCB. It's know to short across it with a screwdriver to drain any charge holding the encryption table. You could also solder a 1K resistor across the pins of it. That will bleed down any voltage when you power it off and cause...

    Garbled Galaga

    That's the self test going... If it's restarting look closely at the screen for an error message to flash by momentarily. I'm OOS on the rebuild kits only because I'm low on one of the parts for it and need the stock to do repairs. Now that VCF Southwest is done and in the books as of a week...
