I picked up the Boomerang pads at the post office on Friday. And boy are they bad! I tried to play Fire&Ice, but it was impossible due to an extremely rotten directional pad. I had to push in a very certain manner to be able to go left. I didn't expect much.. I gave the pads the benefit of my doubt... still they sent me into a world of hurt!
Now I'm getting the PSX adapter from pauwillingham. DM'ed him at tha tube. He doesn't have the right microchips at the moment, but is hoping to have two adapters ready for me in a couple of weeks. In the meantime I need to figure out what I want to do with the Boomerang pads.
