Question: Should the genuine Micro$oft remote work after these changes are
made? If you think so, send me the updated xir.o and xpad.o files and I will
include them in the dist. Even if they don't work with the MS remote, I
could include them in the dist so that users who need them could easily
install them and use an aftermarket remote.
