Ugh, finally I got this sent off... smile He should have it soon, along with the list of games I posted a page or two back to get some more stuff into MAME. All are VFD, I think with the Hitachi HD38800 processor, so they should be pretty straight forward for dumping and emulating.

I got the games earlier in the week and tonight I desoldered everything. All games do have HD388xx parts in them, but Defender is weird. It has a 64 pin shrink dip version of the HD38820, which I didn't even know existed! I will have to solder wires onto it to dump or something. It should dump fine, I just need to connect up to it. the Pucki and Monsters game has an HD38750 on it which is kind of surprising, since that has a smaller ROM than the usual HD38800. I can dump it, though so no big deal.

So I have 8 CPUs ready to dump.

Kevtris dumped Pac-Man 2 for the Entex Select-A-Game.
This means all Select-A-Game..s are dumped now. For them to be properly playable on MAME they will need artwork though. For example the pacman game has a maze overlay.

only 6 games total on it actually

Hello folks, longtime lurker here. I'm really proud of all the great work you guys have done!
Just checking; is it true that these roms still haven't been dumped yet?

Yes. At least one version of each G&W is dumped and emulated, but certain alternate revisions have not been sourced.

The first two have visible or audible changes and so are relatively easy to identify. The last one is, I believe, differentiated based on a different silkscreen on the microcontroller itself. As a result, the last one will likely be particularly difficult to track down, since asking the average seller to just unscrew and open up the G&W being sold is a bit of a big ask.

To elaborate, we have the original green version of Judge dumped. There is a scoring error in Game B which gives one of the players an advantage in a certain situation. This was corrected by Nintendo and the fixed versions came in a purple case instead of green.

We also have the original version of the Mario's Cement Factory tabletop unit dumped. This plays a jingle when you start the game that sounds exactly like the bassline in "Another One Bites the Dust". Newer releases had an original jingle in it's place, most likely due to a rights issue.

Helmet originally had a glitch where you could get the game to have two characters on screen at once. The game code is CN-07. The corrected version that has been dumped lists CN-17 on the chip despite still saying CN-07 on the outside case. Besides opening the case as Just Desserts mentioned, the only other way to tell if it's an original CN-07 version is to get the game to glitch.

Excellent! Thanks for the specific info. Would love to try and help track down some of these alternate versions.

Judge is easy to track down. There are always a few on ebay. They just tend to be a bit pricey for what it is. There are Cement Factory's out there but they are even more money and would require the seller to figure out which song plays at the start. Helmet would be very tough to find the correct one. Even getting the glitch to work is fairly complicated and I doubt any seller would want to open their unit to find out which they have.
