Of course, hap! I know what to do after disassembling. Good pictures, and if I will have some free time, svg's for lcd segments with numbers.

JD, I will look for possibility to get at least one handheld (for beginning) without post office. Will PM to you!

Sorry, I was out of town last week and I've been playing catch up. I've got lots of work through Thanksgiving, so I haven't had a lot of time to work on the handhelds. Thanks, hap, that's a better answer than I would have had anyway!

The fellow that sent me the Tiger games has a few that he would like to not be destroyed, and I've been working on dumping the melody ROM of the 511s and 512s. There's no way to access the melody ROM from code, so the only way to get to it is to play the melodies and capture the audio output. But the melody circuitry works differently while in test mode, and there is a command that doesn't play a note but sets a flag that the code can test for. So I've been trying to find work-arounds for those problems.

Someone asked me for the Furby source code, so I'm going to scan it as I can. Here are the first 30 pages: www.seanriddle.com/furbysource1.pdf

Figured you were probably just enjoying the summer, hence not bugging you about any of the remaining Elan / Xavix / Other etc. either :-)

I think all those games remaining are either with TSOP pads and 16-bit data buses, or without pads. I'm not sure what to do with the ones without pads; it's going to take hours to track down every trace, scrape off the lacquer and solder wires to them. Even when I finish up work this year, I don't think I want to spend all my free time doing that.

I recently ordered some tiny pogo pins to see if I could build a rig for dumping the PCBs with pads faster. The ones with 8-bit data buses are bad enough to solder to, so hopefully these pogo pins will be small enough to work. But those TSOP48 pads are really close together; I may be stuck soldering to them.

I had a PCB made to fit in the Game Key slot of the Jakks TV Games, so I hope I can dump the games that have that slot. After I figure out the pinout, I'll just need to find the /CS line of the on-board ROM.

yeah, the Elan ones were 16-bit bus ones, but are the ones I'm most likely to make progress with in the near future.

the remaining XaviX ones are mostly no-pads, and likely to be a pain.

I'll see if I can find the list from before

might be that the no-pad ones need moving on to somebody else to trace out in that case

I hate to ask for more funding after not having anything sent to Sean or dumped yet despite so many people helping out earlier this year, but I just wanted to say that there are a couple of exceedingly rare triple-screen LCD handhelds up for buy-it-now on a local auction site right now. The seller wants 1500 SEK each, or about 166 USD, which sounds about right for how rare they are.

PM me if you can help.

Well, I apparently can't edit my post after a certain amount of time, so: Disregard the above post.

Someone rightly pointed out on another forum that the person selling these games wants roughly 50% more than the absolute maximum that one should reasonably pay for a triple-screen V-Tech game, so I think I'm going to pass on them. Especially since one of the two games is like half that price on a Spanish auction site already.

I'll take a look at the remaining games and see what's what. I'm pretty sure that all the XavixPort games except Golf have pads. I think there are a couple of non-XaviX games with 16-bit ROM that have pads.

I finished scanning the Furby source: www.seanriddle.com/furbysource.pdf

I also paid a guy to scan his copies of the Rockwell MM76 and MM77 programming manuals:
www.seanriddle.com/Rockwell_MM76_Microcomputer_Programming_Manual.pdf

www.seanriddle.com/Rockwell_MM77_Microcomputer_Programming_Manual.pdf

I went in halfsies with a guy on Gakken Super Cobra, but it has a Hitachi HD38820, and I don't know how to dump that one.

From the notes provided before, the following are ELAN types, 16-bit roms, with pads. I think these are worth giving priority to over the other TV games at least.
Code
    Real Swing Golf             (74037       x16         48          not dumped      no              ELAN EU3A14)
    Play TV Basketball          (75029       x16         48          not dumped      no              ELAN EU3A14)
    Baseball 3                  (?           x16         48          not dumped      no              ELAN EU3A14)
    Huntin’3                    (?           x16         48          not dumped      no              Elan ?)

These 4 I should be able to get to do something reasonable in a short time, and should help improve the video emulation for the ones currently dumped. As they're not XaviX it's a much more simple architecture to emulate.

For documentation sake, what serial is Gakken Super Cobra's MCU?
HD38820 is electronically dumpable, but it's really complex according to kevtris. It's in MAME under cpu/hmcs40, hh_hmcs40 driver.
