Hah, didn't even think of date codes... smile I'm just used to a little more writing on these things.

It's a 'normal' sized 28-pin chip.

There are something like 103 'round corner' Tiger games. I think I'm missing about 5. If you want a full list, by all means PM me. I would like to preserve these games in MESS, even if there is a small chance they won't work afterwards. Sample games:

* Addams Family, the
* After Burner
* Altered Beast
* American Gladiators
* Back to the Future [aka Ritorno al futuro?]
* Baseball Super Stars
* Basketball, Magic Johnson's
* Batman
* Batman Forever
* Batman Returns [aka Batman Il Ritorno]
* Battletoads
* Captain Planet
* Castlevania II: Simon's Quest

I torched the epoxy glob on the Tiger X-Men LCD game but didn't have great results. I'll try to put it in some acid in the next couple of days. I can see the perimeter of the die, and it looks to be the same chip used in the RZone game Indy 500. I think that's one of the Sharp SM5 MCUs.

I also got Sears Auto Race, and it doesn't use the same Rockwell chip as in Mattel Auto Race; the Sears game has a glob with 28 traces coming out. I'll see if I can get it cleaned up and figure out what it is.

Next batch of games on their way to Kevin... (Should arrive Thursday...)
Been too quiet around here... smile

Bandai Burgertime (VFD) (HD38820A65)
Bandai Pair Match (HD38820A88 & A89) (Two processor chips in this one)
Bandai Pengo (VFD) (HD38820A63)
Bandai Ultraman
Bandai Zaxxon (VFD)
Gakken Amidar
Gakken Jungler

Tried to pick a batch of interesting, and rare, games... Not a lot of people have played the handheld version of most of these, but they are definitely cool (Burgertime, Pengo, Jungler... smile )

I just think you guys are doing a fantastic job. Obviously - I am willing and able to make a huge contribution here as and when you feel ready to dump the games in my collection. Please keep in touch, and I will keep checking back.

Good luck guys.

Didn't know there *was* a handheld Burgertime. Nice!

Great =)

I've been working on Tamagotchi(the very 1st). It's taking me longer than I expected.

Actually, that's really cool too... I think I saw the skeleton driver show up in the source and it reminded me that I still have one of those somewhere. That'll be fun to play with again. smile

I got the new batch of games today. On first impressions, there's some weird stuff in here.

Amidar uses an M81503-702SP which is similar to the chip on frogger, but is in a shrink dip package- a 56 pin sdip. This is an odd package size. I'm sure it probably dumps the same way so I most likely can extract it's programming goodness.

The other issue with this game is the VFD has the white "grid" pattern of amidar printed onto the filter. This is going to make vectoring it difficult because the lines obscure the VFD glyphs head-on.

Jungler has the same chip frogger does, an M58846-702P. (frogger's 701P and I think 700P). Again I can dump this so no big deal.

Bandai pair match has TWO HD38820's in it. One runs the game/VFD and the other does nothing except make sounds. Almost all of its IOs are NC. There's a 4 bit bus and 2 or so control signals between the two.

Bandai zaxxon has a mirror above the VFD so that the two halves of the VFD are "overlapping" each other for a 3D effect. Half the VFD glyphs are reversed because of the mirror.


Bandai ultraman has a very difficult to vector VFD, I might have to let that one go, at least for now (or someone else is welcome to do it :-)

Other than that, should be easy work. I got the two select a game carts apart without damage to the labels except for a tiny bit that shouldn't be very visible once it's back together.

I didn't even open Amidar or Jungler, but surprised they used different chips than Dig Dug...
What is the grid printed on? Directly on the glass, or on the color overlay? If it can be peeled off, you can go ahead and do that...

Yeah, that one surprised me when I opened it... But hey, at least the VFD is REALLY easy to vector. smile

Yeah, that's done to create the illusion of 3D, half the glyphs are overlayed on the other half. Maybe for emulation that will have to be treated as two VFDs on top of each other?

Coleco Zaxxon is similar, but it really does have two VFDs. Using a mirror, your ship (all on one VFD) is super-imposed on everything else. These might be interesting to emulate... Not sure if that makes it harder, or just 'different'.

Haha, I warned you about that one! There's one more in that series too which is probably just as annoying... We can at least get it dumped, photographed and emulated... Figure out the graphics later, there's plenty more in the mean time.

I'll send some 'less interesting' ones next time around. smile
