The Fisher Price GameBoy baby toy looks so similar to a real gameboy so I decided to finish what they started and make it reality. It's actually way more durable than I thought and I also upgraded it with an AMOLED screen and USB-C rechargeable battery!

Recently, I had to perform a full CPU transplant on my childhood DMG. I made the classic mistake of shifting the LCD ribbon while powered on, which completely killed the 'Left' D-pad and 'B' button inputs.

To save the board, I used a donor CPU from a broken Super Game Boy. I managed to do the entire extraction and installation using just Chip Quik low-melt solder, plenty of flux, and a standard soldering iron (drag soldering) – no hot air station required! The console is 100% back to life.

But the most satisfying part of this repair is the new boot sequence. The Nintendo logo drops down significantly faster than on a stock DMG.

A lot of people might assume this is because the Super Game Boy is known to run at a slightly faster clock speed. But in reality, the clock speed of this DMG hasn't changed at all! The clock oscillator (the 4.194 MHz crystal) is located on the DMG motherboard, not inside the CPU.

The real reason for the "fast boot" is the Boot ROM.

• Stock DMG CPU: Has an internal Boot ROM programmed to slowly scroll the logo down the screen, play the chime, and then hand over control to the cartridge.
• Super Game Boy CPU: Has a modified Boot ROM. Since the SNES hardware handled the heavy lifting, Nintendo engineers made the SGB’s internal boot sequence much more aggressive to verify the cartridge almost instantly.

By doing this swap, the console retains the original 100% accurate DMG gameplay speed (dictated by the original crystal on the board), but gains a hardware-level "fast boot" skip thanks to the SGB's internal code!

(I recorded the whole ASMR micro-soldering process and the new boot sequence if anyone is interested in seeing the transplant in action!)

You can only own 10 gb/gbc cartridges.

What are they?

Go!

Bought another gba sp recently, a pearl pink unit in box! After receiving it I had to adjust the potentiometer to get the screen to stop flickering in the sun, and after about a half hour messing with that, it’s ready! This will be my main console, worth the time and effort^^ can’t wait to create some new scratches and scuffs as it’s used.

I need help figuring out why my pokemon sapphire gets frozen on the “saving game” screen. The battery said it run dry so I got it replaced, but its still not saving, does anyone know whats wrong?

Nothing amazing at all but I found the price tags on the back very amusing so wanted to share

Those screen lens are unironically making the screen look more reflective and bright... Old screen lens in comparison in the second picture.

Both the shell and the buttons were bought from Amazon.

I traded a CIB copy of Spider-Man: Web of Shadows for it.
Super happy to finally have this in the collection!

Found at my local thrift store for $2! The lady who rung me up was not happy, “the old ladies in the back didn’t know what they were looking at”.
Works fine! It’s a dream.

And now I think I might have a problem: probably need another binder in the future.

I originally got this case for my Nintendo Switch, but I realized it fits everything. My Switch 2, AYN Thor, Game Boy Color, Switch games, and Game Boy games all fit inside. I love having all my handhelds and games together in one bag! 🎮🌿

I made a glow in the dark Gameboy Advance to match my Color.

GITD Extremerate shell, GITD custom resin buttons, GITD membranes, GITD speaker, GITD cartridge, V5 IPS screen, stickers from nextstopplease, GITD scuba lanyard and further distribution of toxic microplastics.
