Sorry for the delay but:

I would not advice this. It is working, but you will have more flexability using a board with a ATMega32u4 chip.

Such boards only cost like 2 or 3 US dollars / Euro's.


Concerning input lag, I have not noticed lag when using this.

You connected both white and yellow wires? You only need to connect 1, so or yellow, or white. The driver board has two input channels....being 1 white, one yellow. Disconnect one from the pi (it is not connected at all), in your case I would disconnect the yellow wire. Not sure if it will fix your ...

This one worked for me, with or without external power.

Update: I attached only the yellow wire to TV on the Pi. I also attached the red wire directly to the third pin on the ic called ams1117. The only sign of life from the screen is a very dim flash and the screen stays black. Did my screen come to me broken? I have the same screen and board. Attachin...

Just found out I'm using a B503....not a B103......not sure if they are compatible....but for the schema: schema.png Note that you can combine the output to the speaker for both channels (you need an additional schema with additional resistors for that) ....for simplicity....I just connected one cha...

Something like this. I do not know your audio jack wiring.
But again....I will check my exact wiring this evening (4 to 5 hours from now for me

Looking at your wiring, you wired + and - of the left channel into both inputs of the pot. You only need to wire the + into the pot (and of course the ground as well). (Your audio will be mono). Or add the + of the right channel to the pot as well. From your picture I would say, from left to right: ...

Wow, that's what I'd call a real hack. Any videos of it in action, sending keyboard inputs? No Video's yet. I was actually using this as a controller for an arcade cabinet I'm building, but I removed all wiring to start over, using multiple Pro Micro controllers. For my GBZ builds I'm also using Pr...

Yes. For example, take a look at the guide by sota: http://www.sudomod.com/forum/viewtopic.php?f=22&t=1766 Concerning the screen. It will have better picture quality compared to composite, but it is using SPI, so the refresh rate will be low (probably to low). Also it will not fit, because it is to ...

No. The 328 Does not support USB HID.

Look for an Pro Micro clone with an atmega 32u4 controller.

Check the guides, there are a couple of examples there.
