uPD557L is my logical guess(very good chance, I believe).
If you're interested getting it emulated, and kevtris is still interested dumping these handheld MCUs, we can add it to MAME soon. =)

I visually dumped Konami Contra and updated the ROM on my site:
http://www.seanriddle.com/contra.html

There were several ambiguous bytes in the patent that I fixed.

The melody ROM is the same as in the patent except the unused 19 bytes on the end are $3F instead of $FF (its only 6 bits wide).

I have the Nu Pogodi IM-2 here, but apparently some (battery?) fluid got inside the LCD, rendering the left side semi-useless. Maybe someone more knowledgeable can salvage it?
PCB is in a rough shape, I suspect it met water at some point, but the game works nonetheless. IC is unmarked, but pinout seems to match КБ1013ВК1-2 from Russian thread.



cYa,

Tauwasser

After working on the Konami LCD games, I started looking at the G&W games and the Electronika game Tauwasser sent. The dark splotches on the LCD are actually voids where the liquid crystal is absent. I guess that some leaked out, and that those areas are where the glass plates are farther apart. I can press on the glass and see the liquid move slightly into those areas. Without the top polarizing filter, the black splotches are barely visible.

Unfortunately, the lower polarizing filter and the reflective background are glued to the glass, so I can't take the same kind of pics like I did with the Konami games. I put the panel under the microscope, and it looks like I can get pics like the RZone Jedi pic.

But reading through the links posted earlier in this thread, someone has decapped the chip from this game and visually dumped the ROM, and someone else wrote an emulator. The ROM file and scans of the artwork and LCD segments are available. So we just need to follow the traces on Tauwasser's scans to figure out how the buttons and LCD segments are connected, and that should be all the info needed to emulate it.

Hello! It was me. I've emailed hap, but he was very busy.
I've already released a standalone application. Do you want to repeat all my work? Or just to insert my graphics in MAME?

Yes, I did not forget and will definitely add the Elektronika LCD games. smile
My plan was(and is) to get the Sharp SM510 emulation core accurate before I add the КБ1013ВК1-2.

Any issues dumping a PIC 1655A-081?
Found one of these laying around:
http://www.handheldmuseum.com/Misc/RamtexSpaceInvadersBB.htm
And that's what is in it... Fairly simple LED based game, I have the single-game variant as well, but haven't opened it yet...

Is there a link to that emulator? I'd be interested on checking it out. Is it actually emulating the handheld or is it simulating it like the simulator available at pica-pic.com?

This is the link to my emulator :
http://tsk-tsk.net/net/NuPogodi_EN.zip

It is genuine emulator, with original firmware of Nintendo Game&Watch series "MC-25 Mickey Mouse" and "EG-26 Egg", because "Elektronka" is a clone of Nintendo.
