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

I recorded a video of the IC decapsulation process. The hot air gun nozzle is visible in the top-left corner, with the temperature set to ~150°C. This method works great for small chips. On larger dies, some compound often remains in the center, which I remove by boiling in rosin

I also implemented serial communication in BrickEmuPy and used it in the Tamagotchi V3 emulation:

Tamagotchi Connection V3 (2006) has now been dumped and emulated. Since the ROM is a full 512 KB, dumping the firmware took quite a while, and I most likely haven't cleaned up all the errors yet. Overall though, it's working.

In this great article, Dmitry shares a link to the GPLB3x documentation. When I tried searching for it myself, I couldn't find anything other than superficial datasheets. While my Tamagotchi V3 emulator is already generally working, this doc will help make it much more accurate.

I decapsulated the Tamagotchi Connection V3. The microcontroller is a Sunplus again, specifically an SPLB32. The etching went well, but there's a major issue: the ROM is a whopping 512KB. That's a lot, my previous maximum was 64KB.

О, у нас тут единение с бразильскими братьями? Мне кажется нас также объединяет и любовь к ретро играм.
Покажите свои коллекции! Может у кого-то сохранились игры Tec Toy или... Zeebo?
У меня есть вот такая копия бразильской Battletoads!

I've added emulations of two more late-90s virtual pets based on the same program: Super Gyaoppi 9-in-1 and its slightly modified version in a big cat head-shaped case (donated by @ksenia1923396). Both run on a Sunplus SPLB20 MCU.

Aside from some differences in the code, this virtual pet lets you select a 10th character (despite the "9 in 1" label on the shell). The Super Gyaoppi also has one, but it's not selectable due to a software limitation.

Last summer, @OKDecc sent me a D-Power Digivice for decapsulation. I couldn't get good dash etching results back then, and I didn't have a proper lens for photography, so I've only just returned to it now. I published photos of the board, die, and ROM archive.org/details/bandai-d…

Some areas of the ROM are completely unreadable, so creating a full dump isn't possible, but I was at least able to see the sprites stored in the ROM

Digimon Ver. 4 has now been dumped and emulated. Additionally, two alternative versions of Ver. 1 have also been dumped. This time I wasn't the one who took the chip photos (the source preferred to stay anonymous).

McDonald's Chicken Nugget Tetris (2023) has now been dumped and emulated. This is a significant achievement for me, as the game's microcontroller is quite modern, and tackling something like this was beyond my reach until now.

Just compare the ROM density to one of the earliest microcontroller supported by BrickEmuPy (photo at the same scale). In numbers, the difference is roughly 1:256.

While looking for information about this game, I came across its original Japanese advertisement:

I once did a demake of the Chrome T-Rex game for the Epson RC-20. I haven't really revisited the platform since, but it'd be nice to dig into the hardware – maybe even write an emulator.
