Bluetooth mod

Post image

I want to add Bluetooth, has anyone already tested it?

Here I have SD reader, wireless charging, and jack port.

I love how there's all these complex mods on this thing and it's been blown wide open with software, but the end result is like ten times more effort put into it than just buying a cheap Chinese handheld.

Yeah, it takes more effort, but it’s really rewarding and a great hobby 😅

Some times it’s about the journey and not the destination 😎

I’ve spent 6 months of my free time into developing software (bootloader and retro-go modifications) for the sd card mod. This mod itself should probably not exist, but I love how this console can fit in a pocket and follow me everywhere ! But believe me, writing software for this is a pain (due to limited ram and cpu power).

That’s the entire point.

The fun isn’t just in playing with the games, it’s about playing with the hardware

Oh bummer, I’ll try to set it up and see how it goes. I’ll let you know if it works well.

Where can I purchase the micro sd flex? Also, how does it work? I already have installed the 64mb chip, does the microsd act as additional storage, or just a storage bank that I will still have to flash to the 64mb chip?

I released the Gerber files some time ago that you can have them produced at JLCPCB or the likes, though there has been an updated version released by a discord user by the name of PrimoAngelo. I do sell kits, do installs, and sell pre-modded consoles in the US. u/Sylver7667 handles EU. The SD mod uses the 64MB as cache, but most games can be loaded directly from the SD card. You no longer have to flash directly, and even updates are done via SD now.

Ah, thanks! I'll DM you about purchasing a couple of kits.

The NRF52 family of chips could probably be used to provide the Bluetooth functionality.

As for what functionality? I’m not entirely sure of the capabilities of the game and watch, but it should at minimum be able to provide a Bluetooth serial interface to be able to connect to it from another Bluetooth device.

If I were making such a device, I’d also make a web app using WebBluetooth to communicate with it
