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.
I reverted it to original state though I'm not sure if it was worth it. Nobody is ever going to play "Active Life" again.
