I'm pleased to announce that I've worked with @p0rchio to assume web hosting for https://t.co/Etu7kWHmrj - the site will live on! I'll also taking over as "editor-in-chief", so if anyone wants to contribute retro console, computer or arcade repair write ups, hit me up!

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. https://t.co/tJKli0wid0

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! 😎

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

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.

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

Playing Batsugun tonight. #shmup

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

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

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. 😎

My buddy's AV Famicom w/NESRGB V1.4 mod started dropping V-Sync after warming up. I reached out to Tim Worthington, the mod creator, who said to replace the MCP6561T-E/OT (sync separator) and SGM8051XN5 (composite video buffer). That fixed it - thank you Tim!

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. 😁

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

I just repaired a bootleg Cave DDPDOJ #arcade #shmup board. It had a damaged clock crystal and wouldn’t boot. One part swap later and now it’s running like a champion! 😎

Happy New Gradian Year 2025! 🗿 #Gradius #NewYear

I’m back at the workbench today updating a CPS3 security cartridge with the Darksoft UltraBIOS and programming a set of CPS3 UltraSIMMs. I’m not much of a fighting game guy but the art and presentation on these games is gorgeous. #arcade

Just in time for Christmas, @_ShootTheCore published a writeup on repairing faulty art assets on a Cave CV1000 Muchi Muchi Pork #arcade board. Happy Holidays!

It’s a good day to dump a Cave CV1000 #arcade board. Major kudos to Buffi for his research and scripts that make this possible.

❤️😍

I’ve been an Irem fanboy for decades but I only learned just now what the acronym stands for.
