Spent the evening playing on some arcade machines and listening to some 80’s tunes at RGP 5.25 arcade meet. I made a couple of snapshot videos during the evening. Unfortunately you don’t really get a feel for the number of people that turned up.

Highlight of the night for me was the Rodeo shooting gallery, electro-mechanical game

Leg Levelers and more sanding

The leg leveler mounting plates on the Baby Pacman were badly rusted, full of crud, and the thread would not allow me to screw in any legs. I wondered whether it would be possible to remove the plates and replace them with new ones. The problem was that it would be hard to find suitable replacements, and on a second inspection it looked like they would be extremely difficult to remove.

I purchased a 3/8″-16 tap and reversible T bar in the hope that I could re-cut the thread on the inside surface of the hole. I went for the 3/8″-16 size as this seemed to be the standard Bally leg thread size for this type of cabinet.

I applied lots of WD40 to the thread and tap to keep it well lubricated, as I slowly did 2 turns clockwise, and 1 turn anti-clockwise, for the entire thread.

The result was that I could now screw the leg levelers into place!

It was extremely important to get this done, because the damaged to the bottom of the cabinet was caused by it being dragged across the floor without any leg levelers. As the cabinet would now be off the floor, no further damaged could be done as I continued to repair the bottom.

I also did a bit more sanding to cabinet and took measurements of the side artwork position on the cabinet, so I would put it back in the same position.

RP2C03B chip from PlayChoice-10

I’ve just recieved this chip in the post from a faulty PlayChoice-10 PCB.



I can actually use this same chip on a Nintendo Vs PCB as a PPU to play the following games:

Vs. Tennis
Vs. Battle Cry
Vs. Mahjang
Vs. Pinball (JAPAN)
Vs. Star Luster
Vs. Golf (Japan)
Vs. Duck Hunt (MDS-DH)
Vs. Tetris (by Tengen)

I was a bit concerned that the chip didn’t have a heatsink, but it turns out that unless the game is running for very long periods of time the heatsink is not required.

I’ve been trying to get hold of any Vs games that have an RP2C04-0003 PPU. This has proved really difficult! Either the games never seem to come up for sale or they sell for ridiculous prices. I even tried various arcade forums in the UK and the US and had no luck whatsoever.

Finally I came across a working rom set and PPU for sale on eBay US that was advertised at a realistic price, and I snapped it up. It arrived in the space of about a week, which was really impressive.

What’s really exciting to me about this, is I can finally play some of the more hard to find games by burning my own eeproms. These include:

Vs. Dr. Mario
Vs. Goonies (this requires an extra Daughter board)
Vs. Balloon Fight
Vs. Soccer
Vs. TKO Boxing

The big game for me in this list in Vs. Balloon Fight!!! It’s a brilliant game and supports two player simultaneous play on two monitors on a Vs. Dual System. The only problem now is that I need another RP2C04-0003 PPU!!!

Hopefully this might not be the case! I came across this website and project the other day:


It’s a project to make a universal PPU for Nintendo Vs games/Playchoice 10 systems. I wait in anticipation for this to be released
