Well, I just finished writing a script that calculated every possible 16-bit CRC on both firmwares, both bit-reversed and not, with each of -1, 0, 1 as the initial value. Unfortunately, I didn't find any CRC that calculated the desired value for both firmwares at the same time. The only thing I didn't try yet was inserted the 48/47 bytes before calculating the checksum. Still, since they're not in the download, I'm not too hopeful about that, but we'll see... Thinking about it, a CRC might be a little overkill for the PIC in the remote to calculate (they're kinda slow even on my 2GHz x86). Perhaps it's a simpler algorithm like a checksum - have to go find out how they work. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
