As it was not yet recognized in TAPClean, I was sent a version of BMX Simulator I was not aware of. It uses Visiload T2, but the initial decoding parameters for extra header bytes and bits in a byte were different from anything else we’ve seen so far.
With version 0.30-pre2 of TAPClean the tape is fully supported and cleans to 100%.
On a side note: I will have a thought about the correction of these annoying oversized pulses in Visiload tapes that still require manual fixing.
Details of the version of BMX Simulator I wasn’t expecting:
CBM Data CRC32: $F1340213
Magic CRC32 : $69DE02B6
