Sounds great actually, that post would make a good tutorial. I did what you wrote but I deleted the ledblinky lines in the bat file as I wasn't using it. I got it all to show and fire up within HP but I could never exit out of it, got frustrated and wiped it all out. The bat file should have been included in the latest wip, you may need to just add your paths in instead of making one. If you figure out the exit issue please post it up as I too was suffering from that.
EDIT: In the JB controls config file I had to delete any other entries that were already there that pertained to the keys that I was using on the cab otherwise it all got confused. I think if I was going to do it again I would just wipe out all the info in the config and just add what I was going to use from the cab.
