Can’t believe I did this 15 years ago

Borrowed a friends soldering iron and spent two hours making sure everything was absolutely perfect… for the wired interface to not work at all and be stuck using the touch sensor. Oh well. Really happy with the result anyway. 3.0 M2 IPS Funnyplaying kit with USBc rechargeable battery as well. Have heard of problems with the battery but it fits so well I didn’t have to trim anything. If I run into problems I’ll just take it out and go with rechargeable AA’s! Didn’t know the Start Select buttons were actually just membranes… thinking about getting red ones now I think that will look cool.

Hey everyone! Long-time Game Boy Camera fan here. I got tired of the copy-paste-from-serial-monitor workflow every time I wanted to save photos, so I built a little web tool to fix it.

**GBP Downloader** — a single HTML file (~60KB, zero installs) that:

- Connects directly to your Arduino over **Web Serial** (Chrome/Edge, no drivers)

- **Auto-reconnects** when you plug the cable in — no more clicking Connect every time

- Decodes the V3 raw packet stream in real time, including **RLE decompression** for Pokémon TCG and other compressed-mode games

- Shows photos in the gallery the instant the Game Boy sends the PRINT command

- **8 palettes** to choose from (BGB, DMG, B&W, Pocket, Sepia…) with live re-render

- Optional **auto-download** — saves to your Downloads folder automatically

- Batch ZIP export for the whole gallery

- Works offline too — drag & drop a serial capture .txt to decode it

The UI is styled after the DMG-01 shell — grey plastic, magenta A/B buttons, the purple DOT MATRIX stripe. Felt right for the project.

Built on top of the amazing [Arduino Game Boy Printer Emulator](https://github.com/mofosyne/arduino-gameboy-printer-emulator) by Brian Khuu (mofosyne) and contributors — this is just a nicer frontend for their firmware.

Happy to answer questions about the wiring, the firmware, or the web tech side. Would love feedback from people who actually use their Game Boy Camera regularly!

Hi guys,

I’m a modder since two years now, i’ve always bought Hispeedido or FP and Extremerate stuff to mod my gameboys.

Hispeedido is now closed on AliExpress and their website is permanently out of stock.

Where do you buy all your parts ? I see a lot of new mods with Hispeedido parts here, but I can’t find anything, I have like 6 or 7 more gameboys waiting to be modified.

Thank you for your help !

Latest project I have been working on finally completed . Literally built from scratch! Let me introduce you to the Tadboy Color. Yes , it’s a mini gameboy color 💪 can’t buy these , only can build them with Custom 3D resined case with my initials . Onto the next project .

Frogo is the man

Hey everyone! I just rolled out a big update for my free Game Boy editing/modding web tool, and I can't wait to share the new features with you guys.

Here are the main upgrades:

✅ Component Rating System

Rate any modding components you've used without mandatory purchases. Share your honest experience to help the community pick better parts and avoid bad components.

✅ Virtual Build Editor

Mix and match parts to design your perfect Game Boy build. It’s super handy for calculating total costs and comparing the differences between various components before you actually build.

✅ Public Sharing Page

Showcase your custom Game Boy builds! Share your setup publicly and get feedback & praise from fellow modders.

I’ve also added tons of new components to the product library recently.

Additionally, if you are looking for rare or hard-to-find Game Boy parts that are out of stock, feel free to DM me. I can contact suppliers to hunt for their hidden stock for the community.

Hope this tool makes Game Boy modding easier for all of us. Any suggestions or feedback are highly appreciated!

No downloads, completely free for the retro Game Boy community. Have fun building!

Hi all I recently picked up trying to mod and repair old consoles. My current project is this guy and I'm having some issues. The volume on the console is extremely low. I almost have to hold it to my ear to hear it. I was wondering if anyone could share some knowledge to help me along.

So far I've done a screen and USB c mod. Cleaned the power switch, replaced the volume slider and filter capacitor with a ceramic capacitor. I still can't get any decent sound out of it and I'm beginning to wonder if it might be an audio amp failure.

I've heard that ceramic capacitors aren't a direct replacement for an electrolytic. Could that be why I am still having issues or is this something other people have had luck with? I do have a proper replacement ordered in case that is the issue.

Would one of the modded amps essentially bypass the stock amp circuit or does one feed into the other? If it runs separately I might just throw one in and call it good there if the amp chip has failed.

Side question. There is a small coil at the bottom of the board on the side with the buttons with a crack on the top. Is this tied to the amp circuit at all? It has continuity and I'm guessing it just broke from getting dropped and not from shorting or other means.

Sorry for the wall of text. Thank you for reading and thank you for your knowledge if you share it

I wanted a Charizard theme GBC so i figured why not, plus i now i can trade with my self, plus my current collection of handhelds (still need to mod the other SP, my atomic purple i plan on putting on a frame since ive had it since childhood)

Hey everyone.

Question for anyone who has used an eXtremeRate shell on a GBA SP: do you have this gap?

I recently modded my GBA SP with an IPS screen and an eXtremeRate shell. Everything looks and works fine, except there’s a pretty noticeable gap in the middle of the hinge. I can literally see the screen cable through it, which didn’t happen with the original shell.

Could this be caused by the hinge mechanism not being seated correctly in the new shell? The gap only appeared after the hinge mechanisms fully snapped into place.

I’d rather not take it apart again and unsolder the screen cable just to reseat the hinge mechanism if that won’t actually fix it.

The earplugs works perfectly, also the volume potentiometer works. I have just replaced the original speaker without success. Earplug connector and board cleaned with flux and 99% isopropil, no capacitor or resistance visually damaged. Any idea?

Thank you!

Copied someone's GBA from here because it was so beautiful!

Completed for the upcoming 'When Monsters Attack' exhibit at The Mystic Museum.

Looking to buy on Marketplace but guy says it was in his tub of games. Not sure if it's real or not. Thanks!

I was going to install an IPS screen to My gba and the dry test looks like this 👀 is it broken? I tried reseating the ribbon cable a few times but no luck

Hey!

I modded my first GBC and if i turn on sound too loud the red power led starts blinking, or if the batteries are with low voltage it gets into a boot loop and does not even start.

I have the following mods:

- FunnyPlaying IPS Laminated v2

- FunnyPlaying Button Leds

- Retrosix Clean Amp (not set to louder)

- Retrosix Clean Power Regulator (removed original power regulator)

I suspect the problem it's lack of power, i use basic AA batteries, but at same time i have also readed that this Retrosix Clean Power it's a bit of a problem and the original one it's perfectly fine to run all mods, could be the power regulator ?

Or could be the Clean Amp that draws too much power for these basic batteries ? I have ordered an USB Lipo batteries with Wifi charging from Aliexpress to see if it get's me more juice.

I don't see any damage where the legs would be but I need to clean it up and see if any pads were damaged.
