After Balrog figured out that the SystemA MCU was a Sanyo, I looked for the other similar dies that I've found.

Acclaim 1943 has a 1C5734
Grandstand Game Player has a 1C5738
That SystemA game has a 2C5732
Tandy Pirate has a 3C5800
RSA SecurID has a 3C5800

Some of the datasheets have instruction sets/opcodes.

Nice find =)
I saw there was talk on the shoutbox about sending one to caps0ff for staining.
Or if any of these are a chip(instead of epoxy blob) then, knowing the pinout, it's worth trying to dump electronically.

I found that the LC5733 datasheet has instruction sets/opcodes for that series (2C57xx I believe).

As for epoxy blob, find someone who has a wirebonder wink Sanyo was nice enough to include pad information in their datasheets.

so are we sure all these can be dumped electronically? 100% match for the datasheets? no protection? are the traces all exposed outside of the blobs, or would it require more delicate work than that?

are deglobbed ones dumpable, or do we need a donor one in each case to know what the glob is inside first?

Not sure.

Yes.

> no protection?
Don't know. Someone will have to test with a packaged chip. Mask programmed chips very commonly lack protection, though.

> are the traces all exposed outside of the blobs, or would it require more delicate work than that?
I believe no — would require live decap and wirebonding out the test pins.

> are deglobbed ones dumpable
This depends on Sean's process. Obviously it would be less work to wirebond only the test pins rather than all the needed ones, but there might be other concerns.
EDIT: Probably not.

If I have to clean off epoxy with sulfuric acid, the pads are etched pretty badly and I'd be surprised if they could be bonded to. Occasionally the epoxy comes off cleanly, but that still rips the bond wires off the pads. The pads for the test pins would be OK, but other pads necessary for dumping the chip might not be bondable.

I've got some more LCD pics to vectorize if you want to smile I started on Biker Mice From Mars thinking I could get it done before I left on vacation, but I've spent a few hours on it and still have more work to do! I think I'm cleaning specks that won't cause any problems. I need to figure out how to ID the bad ones, and leave the tiny ones alone.

The first 4 are the same style of games as I've been doing, but Batman The Animated Series (and Biker Mice From Mars) are the larger "girls-style" games. Zorro and Battle Arena Toshinden are RZone games, and Starfox is a watch game.

Unfortunately Zorro had a 2nd chip under the glob, which I'm sure is ROM used for sound effects. I didn't want to deglob any of the games with 2 globs since I can't read the bits visually, but I'm not sure how I'd dump that one anyway, since the traces were under the glob.

I bought 2 Starfox watch games; one has a headphone jack and the other doesn't, but it looks like the LCD panels are the same, and I bet the code in the chip is the same, too. I deglobbed the one with the headphone jack and it has what I think is a Sharp SM530. The ROM is split into 2 sections, so we'll have to experiment to find the right way to transcribe it. Both also have a 2nd glob that looks like a 1K ROM used for melodies. I think it's a Holtek, but haven't found a data sheet. The die says HT3139.

The Starfox display doesn't have many segments, but I looked at a couple of youtube videos, and it looks like I got them all. The SM530 can only do a max of 96 segments (2x48).

I had to make a new PCB for taking pics of LCDs since the pitch on the Starfox panels is a tiny 0.7mm. On the back side I put 0.8mm pads for the rest of the RZone LCD panels.

I need to buy some glass polarizers; the plastic ones scratch too easily. I've used all 8 that I bought already.

Ok I'm on it =)

For the SM530, I can start with a disassambler.
*edit* I can't see anything in the SM530 datasheet that suggests why it needs the ROM in 2 sections. Page layout and programcounter is normal. If I had to guess, they simply needed the room on the die for other traces.
