PS3 HRAP3 converter?

Hi, my school is hosting a sf4 tourney and its going to be on 360. I have a hrap3 for PS3 and want to use it in the tourney. Is there any converter switch or something along those lines so I can hook it up to a 360. If anyone knows where I can buy something like this, a link would be much appreciated. Thanks.

sorry there isnt ps3 converter for xbox 360. But ifu have any ps2 pcb on ur custom stick or hori ps2 there is 360 converter for that but u also need 360 wired controller to work it.

There is one, but it sucks.
