Whew. Finished my stick mod this morning. I took a stock Hori Wii Fighting Stick, and replaced both stick and buttons with a retinue of all-Sanwa parts. At first I intended to replace the stick with a Seimitsu, but the LS-32 stick I have on hand would not have fit easily. I would have had to epoxy the stick harness into the shell, which isn't too bad of an idea, but I wasn't prepared to do that right now, so I switched to a Sanwa JLF stick. Actually, I ripped out the stick from a HRAP3 I have and used that. I used a blank breadboard as a buffer between the PCB and the bottom metal plate. The guides online tell you to coat the inside of the plate with electrical tape, but that seemed a bit ghetto to me, so I did this instead.
The most annoying step was probably the soldering - I originally used 18 gauge wire to connect the buttons to the PCB, but the space is extremely tight in there, so much that the tensile thick 18-gauge wires wound up being too much for the board above it. I had to remove them and re-do it with thinner 22 gauge wires.
I need a Wii/Gamecube game that uses all the buttons so I can test them all, but I can't think of any aside from the Street Fighter games on the VC. Anyone have any other ideas? Maybe Ikaruga allows button mapping and I can test it out that way.
Here's the finished stick:
Here's the innards post-mod:
