  1. Namco System 11 - Garbage Audio Samples

    So I have Tekken 1 and Tekken 2 Ver. B boards. Tekken 2's CPU board had a bunch of issues, so I've switched it with the CPU Board from T1. Regardless of that, both games spit out garbage and irritating samples in the music tracks, which leads me to believe the problem is specific to the...
  2. Neo-Geo MV1 - Garbage Graphics

    A dinosaur of the Neo-Geo fleet, I recently acquired a broken MV1 off eBay. Inititally it booted to a Work RAM Error screen as a result of a minor battery leak, with some evidence of corrosion around the closest two surface mounted Sony RAM chips. I cleared all that up with isoprophyl, cut the...
  3. Sanyo EZZ-C - Vertical foldover after warmup.

    Just when I thought the troubleshooting party was finally over. See the pics here. Basically after 15 minutes or so I start to get a curl on the vertical right-hand side. I've done a FULL capkit (including filter and NPs) and it was operating just fine until last week. B+ is spot on. A real...
  4. Taito Space Invaders Cocktail, turned Gyruss.

This is the culmination of about three months of on-and-off work on an old Taito Space Invaders cocktail I bought off eBay...

    What's the deal with Centuri Gyruss boards - inverted sync? So my restore of this Taito cocktail is mostly complete, and I finally fired up my Gyruss board today after building a JAMMA -> Konami Classic adapter. Works great... with a slight problem: the image is really dark. I've had other...
  6. Nanao MS9-29 VR450 (SPC15) Pot Value

    The schematics for this chassis are unreadable, and mine does not match the Sega Touring schematic. I have a dodgy 15K pincushion pot (SPC15 - VR450) that's causing all kinds of irritating shakes: LtIyjkD2Hbw It's (hopefully) the final piece of an ongoing puzzle. Any help?
  7. Sanyo EZZ-C Super Fun Happy Slide

    Hey guys, Long time lurker, first time poster. This is a write-up I've done on the neglected 13" cousin of the 20EZ and my status with mine so far. Only now I've fitted a replacement D1090 and a new IC, and I'm still having a really bad time. What I've done with it up to this point: -A FULL...
