Working USB<>PS1/PS2 controller converter for ddr dance mats?

[MilesCW]

Hello,

is anyone using a working converter so you can use your old PS1/PS2 controllers for recalbox? If yes, which one is it?

I have two official Dance Dance Revolution dance mats here at home but the converters I tried aren't really working. I would like to play with some friends the PS1 DDR games.

Thanks!
