ShootTheCore published a quick writeup on his repair of a faulty clock crystal on a bootleg Cave DoDonPachi SaiDaiOuJou board.

I’m pleased to report that the #arcade CPS3 adapter for the Open Source Cartridge Reader developed by herzmx is the real deal. I can now erase and reprogram a CPS3 security cartridge in 2 minutes! I wish I had this thing years ago. 😁

Now that the Irem M92 #arcade Multi is complete and starting to ship, I’m selling off several of my spare M92 game boards that I used in testing. Each one gets a fresh capacitor replacement and jumpers installed where the Multi requires different settings for future-proofing. 😎

I’m going to try my hand at BGA reballing. This should be interesting…

Just traded some JAMMA boards for an Exa-Arcadia setup. There’s enough here to keep me busy for a long time! #arcade #shmup

Playing Batsugun tonight. #shmup

I'm getting back to arcade board repairs. Latest is an Irem M92 with bent pins on the GA22 chip. It took 20 minutes under the microscope with sewing needles and desoldering braid to straighten the legs. Resoldered legs to pads, confirmed connections, and the board works perfectly

Repaired a UPL Black Heart #arcade #shmup board this evening. The NMK 902 custom chip used for rendering the FIX layer for the title screen and HUD failed. Swapped in a replacement from a Thunder Dragon donor and now it works great.

It’s very Xexex in my workroom tonight. #arcade #shmup

In for servicing is a Neo Geo 6 Slot MVS board. The audio used to fade out shortly after power on but a full capacitor replacement sorted that out. I swapped the old clock battery for a rechargeable coin cell too. These boards are large and in charge! 😎

If anyone likes hearing me lecture on arcade boards, I just posted a 45 minute tutorial video on installing the new Darksoft Namco System 2 Multi kit. youtu.be/x3UTDccPb5g?si…

Sadly, my mother has passed and I cannot afford to lay her to rest the way she deserves. So I am asking if you have it in your heart to donate to help, any amount and I mean any amount no matter how small truly helps. Please share if you can. ❤️🥹 gofund.me/284989ab0

I got a dead Sega System 32 #arcade board up and running again yesterday. Culprit was a dead TTL clock buffer chip. Full writeup on the diagnosis coming soon.

I thought I was done with this Sega System 32 #arcade board but playtesting revealed that it would still freeze up periodically. It seems that another TTL clock buffer just to the left of the one I just replaced is bad as well - I even cross-tested it with two testers to be sure.

A busy evening tonight repairing both a Seibu Kaihatsu SPI #arcade board and Raiden Fighters 2 cart. SPI Revive by Trap15 brought the SPI board back, and reflowing the solder on several SMD ROMs fixed the jailbar graphic corruption in RF2.

ShootTheCore just published a writeup on reviving a Seibu Kaihatsu SPI mainboard with a corrupted region code, and resolving jailbar corruption with the graphics with a Raiden Fighters 2 cartridge. #arcade #shmup jammarcade.net/seibu-kaihatsu…
