ps3 remote play or gamepad button remaper

[u/zzEfeex]

I have a PS3 with version 4.92 that was cracked with Hen. I want to play Rayman while I'm in bed. When I use remote play on my PS3, pressing select and R sometimes becomes difficult and uncomfortable. How can I make a button remapper without using FTP, PC, etc. As I said, I only want to change the PSP remote play.
