Would be pretty cool to see games like Entex Space Invaders or Pac-Man 2 emulated, fingers crossed it won't be too hard smile

Impressive progress that's being made here lately.

ssj: pac man 2 is dumped and the vfd vectorized by kevtris; all we need is a hitachi hmcs4x (not the later hmcs4xx, dunno what actually used that later one) cpu core. Stiletto is working on scanning some docs and once that's done work can begin.

oh nice, wasn't aware of that!

You guys should have some sort of index of what has been dumped/emulated already within the range of this "little" project smile

As well as the cost to reprogram the game for a different chip, they had to redesign the PCB, so there had to be a good reason.

I'm guessing there weren't enough COP444's available. Handheld Museum says over 800,000 games were produced. I bet it sold better than expected and they had to scramble to keep up with demand.

But that doesn't explain why they changed the case. It seems like they would have used the same molds. Maybe there was some rights issue, and they owned the general design but not the specific implementation? Once the game took off, it was cheaper for them to redesign everything?

I found some interviews with Rick Dyer, but they pretty much skim over the handheld games he worked on and concentrate on Dragon's Lair.

Oh, and I picked up a Speak and Read.

Lord Nightmare has some items for Speak & Spell and friends listed here, which could probably be updated:

http://www.mess.org/dumping/have#in_lord_nightmare_s_possession

But if we're talking about every handheld game with an MCU, it's quite a large category, I'd imagine.

Has anyone looked into the Game & Watch? I just read an interesting interview about designing those.

http://www.plasticpals.com/?p=23596

They're described as using an unmodified calculator chip. It seems that the first ones were more discrete logic type games like Pong. But at some point they switched to programming a CPU.

I was mostly speaking of the ones you guys dumped/emulated since this thread has started which has been quite a few already I know I've lost count, so yeah I guess that would fall in every handheld games with an MCU since this doesn't seem to be limited to only TMS-09xx/1xxx any longer.

Game & Watch games with an MCU? Now that's something completely new to me, not that I'm very familiar with them, but always thought they all used discrete logic like most similar LCD based handhelds.
Madrigal Game & Watch simulators are very decent especially the new versions, but if there is an MCU involved emulation would be far more interesting. These games are pretty expensive though so it wouldn't be something cheap that's for sure.

Bookmarked that link to read later, seems like an interesting one thanks for posting.

Yup, Game & Watch stuff has an MCU, most of them by Sharp I think.

I've got a top metal die shot of Merlin. I'll post the PLAs. I can't find pics with the top metal removed, but I assume I have some somewhere. But I think the PLAs can be verified from the top metal shot.

I'm pretty sure Kevin dumped Maniac (from Ideal); he's got a file on his site that has the same code number that was on the chip I decapped. My game had the PIC1655A version and I was unable to dump it, and I cracked the die when I decapped it. I might be able to match up enough bits to confirm that they are the same, or I can write up the PCB wiring and you can see if Kevin's code works.
