I was reading this thread https://www.psx-place.com/threads/anyway-to-swap-x-o-per-game-with-cfw-ps3.9765/
and it sounds like it may be possible with X and O, but I was hoping it might be possible to swap X with R2. I have a steering wheel that's meant for Xbox 360 and PC, but I got it working on PS3 with a Mayflash NS Magic adapter. But it seems like most PS2 games especially, wanted to use X to accelerate, but the wheel uses R2 and most PS2 racing games other than the Gran Turismos didn't want to let you make any changes in the options. I have always used CEX but I would upgrade to DEX if it would let me do this.
