Also bought mine off AliExpress. It was one of the fake pokemon shell models, so that feels a little cheap but looks nice. Otherwise the unit functions perfectly, no scratches on the screen and buttons are responsive.

Well there are tons of 3d printed stands, as well as the classic nail polish stand. Lots of options out there.

Thanks! Found the stands here

Neat, good work!

Built two of these awhile ago. It works very well. https://lemmy.world/post/9910910

There are and they work very well(3ms latency). No mods required . https://shop.insidegadgets.com/product/wireless-gameboy-controller/

Time to get soldering then

Thanks!

Inside

Space and simplicity. There is not a lot of room in a GBA so a custom PCB would probably be needed from the start. Also the DMG display PCB is basically trash if the screen dies, which is all you need for this project. The GBA equivalent would need a donor motherboard.

Thanks. I was looking at these carts and thought about hard it would be to make something similar that you could use a old shell with. I recently made a SNES to Bluetooth adapter so the code was pretty similar. I really like projects that recycle parts like this.

Thanks!

Thanks! I’m actually doing my first playthrough now.

I used their 3.0 ips screen and shell https://funnyplaying.com/products/3-0-inch-ips-agb-laminated-kit?variant=40480705052733

Thanks!

The sleep mode is also pretty cool.

Yep, maybe I’ll revisit it again after trying it on some more smaller prints. Or just experiment with another jewel.

Yeah one approach is that BLE-Gamepad library supports gpio pins as button inputs, so in theory I could get a baseline of what the Bluetooth stack of the library is by soldering the jst connector to connect the Arduino (that triggers the button presses and measures the result from the Mister SNAC port).

Otherwise I’d basically have to develop my own controller code to port onto various Bluetooth stacks for testing, but that seems like more than I want to do right now.

Without more testing it’s hard to say. I don’t want say it’s the hardware without proof, but would require a much deeper dive into esp32 and c++ than I want to do right now.
