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

@Sosowski Yes, here is a close-up of the core:

@OneBitOnePixel Is it a 6502?

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.

@mluna0101 Unfortunately, none of the classic black-and-white Tamagotchis can be reprogrammed

@OneBitOnePixel Is there a tamagotchi that can be reprogrammed? I’d love to have one just as a clock.

@TheFieryWind Unfortunately, this console is too expensive for me.

@OneBitOnePixel Hello there, I've been enjoying your work, BrickEmuPy, by a lot. Have you ever thought of writing a homebrew game for the Entex Adventure Vision? Thanks in advance!

@LecelMakerman Unfortunately, I abandoned porting :(

@OneBitOnePixel you can finish the core for retroarch?

Some progress on porting to Libretro (runs in a browser on Android). Of course, it's still rough, but you can try it here: brickemu.pages.dev/?core=brickemu…

@SelimSerefkara @OneCloudEmoji Yes, some chips, including this one, require additional chemical etching.

@OneBitOnePixel @OneCloudEmoji See? That's what I'm talking about. Wizardry 😅 While they can do multiple layers why they didn't hide this under some layers etc. This is Nintendo we are talking about. They are against every attempt about game preservation 🤬 Or are you doing something to reveal 0s and 1s?

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…

@kindeiv I take a macro photo of an LCD display illuminated from behind, manually clean up the image, and then vectorize it using auto-tracing. Here's the result of each stage:

@OneBitOnePixel such an amazing work, how do you recreate the LCD draws so accurate? as far as i understand, this is not in the rom, is just in the lcd,

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

@SelimSerefkara @OneCloudEmoji That's right. Here's a partial ROM of this game: dark squares are 1, and light ones are 0.

@OneCloudEmoji @OneBitOnePixel I asked and answer was fascinating, you should be shocked too :) He is opening the chip/black blob inside the real device and READ IT by microscope! READING BY LOOKING AT IT. i didn't even know that is possible.

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

@SVhels You probably mean the original Game & Watch series, which was dumped quite a long time ago.

@OneBitOnePixel Who knows if it still exists but I recall maybe as far back as a decade ago there was a massive collection of such games put together and emulated online somewhere.

@OneBitOnePixel What was the airflow set to ?

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

@v64jr I've already decapsulated this Tetris, it has the same firmware as x.com/OneBitOnePixel…

@OneBitOnePixel Meanwhile, I should correct myself from before: it’s actually TETRIS Jr.

I've decapsulated another Nintendo Mini Classics game, this time Soccer from 2004. I managed to capture an image of the ROM, so it's only a matter of time before it's dumped and emulated. commons.wikimedia.org/wiki/File:5839…

@giuliozausa Yes, after chemical etching the bits become visible.

@OneBitOnePixel The bits seem hidden (implant/active area rom). Is it dumpable?

@Lockster2C02 Yes, the microcontroller has a 6502 instruction set.

@OneBitOnePixel The core in the top-center of the die looks a bit like a 65C02

@v64jr It turns out that USPS resumed accepting parcels to Russia in May. However, the delivery time seems to be quite long.

@OneBitOnePixel I still have a damaged Nintendo Mini Classics “Tetris” for you if we’re ever able to send packages to Russia (screen is rotting). 👍

Interestingly, there is no information on the die itself to identify the microcontroller, but fortunately, the manufacturer kindly indicated the part number on the PCB: Syntek STK55C324.

@MacroWorld21 Nikon 20x/0.75

@OneBitOnePixel What type of lens you used for this? 20X Olympus?
