Hi! I'm new to the forum, and am working on my first project, which is fitting a gamecube-compatible motherboard to a 2DS case (for comfort/nostalgia/smash ultimate purposes). I was originally going to use a GC+ for simplicity, but given that the store is down I decided to go ahead and try with a wavebird motherboard with the added benefit of being wireless. Following @Madmorda's board scans and trimming guide, I've been able to hook up the D-pad, ABXY, shoulder, and Start buttons successfully. Power is supplied by a two AA batteries, like in a stock wavebird. However, hooking up the 3DS circle pad has been completely unsuccessful. With what appears to be the correct pins connected, moving the circle pad gets interpreted as either no movement or simultaneously maxing out the analog X/Y axes, the C-stick X/Y axes, and the left analog trigger. What makes this incredibly weird is that, with the shell being a 2DS, nothing is connected to either the C-stick or the left analog trigger. The respective pins on the wavebird for the two sticks and left trigger are all adjacent to each other, but nothing appears to be shorted. I'm currently at a loss how to proceed. I understand that 3DS sliders aren't supposed to work ideally with a gamecube motherboard. Is the wavebird's handling of analog sticks somehow different? Do I need to connect something to the unused inputs? Any help would be appreciated. I would post pictures, but the screwdriver I'm using for assembly/disassembly was on loan to me so I can't take it apart at the moment.
