AIO 2.2 Borard by Helder

I purchased a AIO v2.2 from Helder back a few years ago. I had to put my GBZ project on hold because of a few things that life threw at me. I recently picked the build back up, got everything working right up until I noticed that the board was not programed, of if it once was, time drained the battery life out of it. Can anyone point me in the right direction on how to reprogram the board, I have very little knowledge when it comes to this type of thing. I would like to finally get my GBZ working so I can actually play the retro games I have been missing.
Thanks,
Heretic aka Max Martin

The board would have come pre programmed and the battery would not affect that. What is happening to make you think it isn't programmed? Regardless here is the info on how to flash the board again if needed:

None of the buttons work, despite everything being wired up right. Where can I get one of those USB programmers from. I have one for something else I was working on, but when I try to use it, it does not detect the board. Any help at this point would be greatly appreciated.

Get a usbasp programmer from eBay or AliExpress .
If the buttons are not working have a look at the data connections from the pi to the board. Do you have pictures of that? The data pads on the pi zero very close together and easy to accidentially bridge when soldering to them

What data connections from the Pi to the Board? I was under the impression that, that was the whole reason I bought the board, so I would not have to make all the connections for each button.

correct. rodocop is referring to the two usb wires from the board to the pi. the button inputs on the board go to a microcontroller that is built into it, but the usb pads on the zero are very close together, and very easy to bridge. also, make sure to twist those data cables together, which increases the stability.

The data connections on helders board are labelled as INPUT D+ and D-. Those need to be connected to the pi.
This is on a different, older Helder board, but you can see the D+ and D- connections.

And have you confirmed that the connections are not bridged on the pi side? They are very close together and easy to bridge. (Use a multimeter to confirm to know for sure).
Also make sure they are connected to the proper pads. As seen in my photo.
Newer pi's don't have the pp22 and pp23 labelled

Okay, I will check that out this weekend, and get back with you.
