Some time ago I saw a video about a ps2 controller thing which included 30 seconds of testing with a dance game. I then remembered the box of random old wii junk I got from a friend a few years ago and the soft dance pad folded in there. I have never played DDR or the likes but I might as well try. Except when I unfolded the mat...
Wtf is this layout??
Apparently it's meant for some wii fit clone that uses a mat instead of balance board. It uses the gamecube controller plug, so I plugged it to my gc and mapped the buttons with metroid prime. They are just randomly scattered (tape marks in pic) so I opened the box rewired it to the least unergonomic layout I could think of.
least unergonomic layout
The choice was between too cramped or buttons being too far apart. I went for the latter because I couldn't reliably rest my legs on the center without triggering input on the cramped option.
After finishing the job I tried ddr on the wii. The mat works. The mat also sucks. It's unplayable.
0/5 can't recommend.
The most expensive thing would be the shipping cost on the FSR sensors, looks like you have all the tools and wiring. Maybe an Arduino off you don't have one laying around but I've seen some hilarious builds with hacked up Ikea cutting boards and the sensors
