Edla Game became the 50th LCD game to be emulated in BrickEmuPy. I'm not planning to stop yet, so follow along!

Another version of Hitorikko has been dumped. The code is exactly the same, and only the sprites differ. Unfortunately, the decapping didn't go perfectly, so there may be errors in the dump.

The Hitorikko Chicken v-pet has been decapped and emulated. Since I don't have its original shell, I had to improvise its appearance a bit.
I've often encountered this type of die in late-90s games, so this dump opens the door to many more.
Thanks to @ksenia1923396 for the PCB!

1/2 Cheap Chinese LCD games from the 2000s–2010s often use very similar chips, typically marked with just a year. Based on their appearance, their cores seem to be some variation of the 6502.
Here are some examples:

2/2 I finally got around to full dumping one of these chips from some kind of "virtual pet". Inspired by @jumarmacato work, I asked Claude to independently figure out the MCU's architecture, peripheral registers, memory map, and other details. Here's what it came up with:

Added D-Tector emulation to BrickEmuPy. github.com/azya52/BrickEm…

From the Mask ROM image, to a C#/SDL3 app! Thank you so much for your hard work @OneBitOnePixel in the extraction! Now, we revel in nostalgic wonder!

So, here are some findings:
1/3 D-Tector – uses a Sunplus SPL191 microcontroller (or something similar). The ROM die has been fully photographed.

2/3 Pocket Pikachu Color – the ROM die has been fully photographed, but the microcontroller architecture is unfortunately unknown (assuming it's even a general-purpose microcontroller).

3/3 Digivice Ver. Revival – uses a Sonix MCU labeled "SLL86F8". Unfortunately, it appears to use flash memory, meaning the ROM cannot be read optically.

Received two packages today: a Pocket Pikachu Color and a Digivice Revival from @ElMadre6, and a D-Tector from @OKDecc. I’ll be working on these devices soon.

Puyolin (ぷよりん) LCD game has been dumped and emulated. It runs on a Holtek HT1190 4-bit microcontroller.

I'm currently working on an Epson RC-20 emulator. The watch has two processors: a 4-bit one and an 8-bit Z84. I'll only emulate the Z84 program execution mode, as I won't decap the 4bit MCU of these rare watches to dump mask ROM. The video shows a Chrome T-Rex demake I once wrote

This is what the game looks like on a real watch: youtube.com/watch?v=gIUXOa…

D-Power Digivice EU 1.01 has finally been dumped and emulated. Many thanks to @OKDecc for sending me the device to dump. He actually sent me two of them, because my first etching attempt wasn't successful.

Tamagotchi Mini 2017 has now been dumped and emulated. Most likely, the dump contains errors, so in the future I will try to dump another copy to verify this.

Die photo of the microcontroller from a 2017 Tamagotchi Mini. The ROM image isn't good enough for automatic bit recognition, but since only ~12 kB of the 256 kB ROM is actually used, I think I can extract it entirely by hand.

Nintendo Mini Classics Soccer (1998/2004) has now been dumped and emulated. As far as I know, this is the first Mini Classics game to be dumped. I hope I come across more games from this series. github.com/azya52/BrickEm…

Photo materials are available on Archive.org: archive.org/details/ninten…

Using an 8-bit microcontroller with 32 KB of ROM for a game like this is definitely overkill.
