. 3 MBC1, 1 MBC3, and 1 MBC30

I happen to have a board from my FunnyPlaying build so I figured I'd give it a shot. Used enamel wire to make the button contacts and got 3.3v from the cart slot. I also removed the caps as to not power any circuits that didn't need (CPU and RAM were donors to the other board). Power is provided via AA batteries.

Still very much a work in progress but it works reasonably well (about 8ms of lag). I want to ultimately create an easier to install PCB rather than the perfboard I used.

An update to my previous post. I was able to improive the average lag by disabling the serial monitor, passing a reference of the controller to the polling logic (eliminating the need to loop over the current state and previous state to determine if buttons should be pressed), and adding a 1ms delay between loops (should have realized that the board need some down time between calls). I've added the code since I think 8ms is a perfectly good lag result for a diy project.

Took a badly marginal gba pcb and transplanted the CPU and RAM into this new motherboard. The soldering was a nice challenge but I had an issue with the cart slot. A pin was bent, so had to fix that before games would boot. Very happy with the result. I've uploaded a picture of the back of the shell as well. https://imgur.com/a/opXFA5B

Also in person, the plastic is not cloudy at all. The motherboard is here https://funnyplaying.com/products/gba-custom-upgraded-motherboard-replacement?variant=40990162059325

Printed using hatchbox wood pla. I had a few issues with standoffs but a little glue fix those right up. I'm very happy with the way it turned out. Just waiting on the release of flippy drive to call it complete.

This was my attempt to create a a SNES to Bluetooth adapter. It works but the average latency was 18.35ms, which I think is too much to be considered a good controller.

This unit was just sold as a parts board. I bought it to use as a donor board but figured I could get it working first (this screen was from a different unit). Turns out someone had opened the power switch to clean it, but somehow a solder blob made it into the switch. That was jamming the power switch. Still a donor board through, the volume slider is pretty rusty.

UV printed shell, new battery, button LEDs, and new screen.

I added some documentation on how I'm automating remote control inputs on the 4k. Examples include a template for an IR transmitter, a python script to parse profile information off the SD card for use in automation, and an example of selecting a custom profile based on its name. Hopefully it can be useful, if only just to give some interesting node-red examples.
