No, you have to set the bit sometimes, else (on some consoles) the condensators of the paddle controllers (which are used here) will charge even without input. The Booster Grip support in Thrust still is a bit buggy, I think Eckhard is trying to find out how it exactly works so z26 can emulate it more correct.
I would recommend to set the bit for some(?) time directly after you read the input. But that's only a suggestion.

I'll disassemble Omega Race soon for two reasons:
1. find out how the Omega Bosster Grip *exactly* works
2. hacking the game for driving controller (if that makes sense)
Have fun!
