Hacked USB controller instead of Teensy

[toiletpaper69]

I'm curious if anyone has hacked a USB controller to use in place of a Teensy with any success? I have been thinking of trying this with a USB playstation controller and use L1,2 and R1,2 with my DMG + board from Kitsch Bent. I'm almost to the point that I must make a decision on my Pi3 Gameboy project. Thoughts anyone?

No need to hack. Just cut the board of this controller and place the pads on the right spots.
Then resolder all the cut off traces and you are good to go.

I started with a keyboard controller board, but it is a pain in the ass to figure out all the button combinations.

Yes, it can be done. I think @banjokazooie is able to do just like that. I too worked on using a usb controller at first but managed to fry the chip so I abandoned it and went the Teensy route.

This CAN be done though I don't think there will be enough place in the case for the GBZ...

I think I will give it a go and cut the USB controller and solder up the traces to see how it goes. I was thinking doing this would make the programming easier. I'm not rushing the project and things have went well so far. I will post picks once I get everything sorted out. Thanks.

If you keep the original controller board of this controller, you do not need any programing, as it will be recognized as a USB Gamepad.
Just make sure you keep everything and only cut through traces you are able to rewire later.

That's the plan, thanks.
