The checksum is calculated by adding together all the preceeding bytes, discarding anything over 1 byte, then ORing together with 7F.
So for the play example:
0x85 +
0x7f +
0x7f +
0x4B +
0x0B
=======
0x1D9
Discarding anything over 1 byte gives 0xD9, then
0xD9 OR 0x7F = 0x59.
daniel, was it the checksum you were having problems with, or something else?
