I started using the D52 disassembler available on this site and notice that my output file wasn't in phase with the input file. Tracked it down to the combination of 2 bytes together 0xOD 0xOA being truncated to 0x0A. This sure looks like it's stripping carriage returns from a CRLF combination, but why would that happen in a binary file? And as far as I can tell those bytes are not part of a string, but actual op-codes.
