Hello, The chameleon tiny pro appears to be changing the data automatically when reading dumps.

Confirmed this by uploading a blank dump (default card within the tiny pro) and each line is being modified. Attached are the dumps, and below I show what happened to the first and second blocks Block 0 Before: BC 59 FC 0F 16 08 04 00 01 38 E3 1F 63 B2 97 1D After: BC 59 FC 0F 1E 08 04 04 11 38 E9 1F 6B BA 97 1D

Block 1 Before: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 After: 10 18 08 10 08 08 00 04 10 18 08 10 08 00 00 04

I'm worried this is related to #29, but unsure of how to troubleshoot.
