Modding A1UP Super Pac-Man PartyCade, yeah you heard that right. There's almost 4 buttons on that Cade, so why wouldn't I?? Using emuELEC booted on a T95 Max+ box. Hooked up a Sanwa and standard US buttons to this, plugged it into the T95 and there ya go! Can't thank these guys enough for paying attention to detail. I would have been waiting another 2 freezing weeks in Canada for a 5-pin cable. Picture shows my super-awesome testing setup, thank you DIYretroARCADE!!!
PS - the board i received was a little bit different than the one pictured on the product page, this might be addressing the issue that another comment pointed out about defective boards. No issues with the one I received in Jan 2022!!
