// known version numbers:
// - 27: v1.1.7
// - current format version
// - adds sample start/end points
// - 26: v1.1.3
// - changes height of FDS wave to 6-bit (it was 4-bit before)
// - 25: v1.1
// - adds pattern names (in a rather odd way)
// - v1.1.4 fixes these but breaks old songs (yeah)
// - introduces SMS+OPLL system
// - 24: v0.12/0.13/1.0
// - changes pattern length from char to int, probably to allow for size 256
// - 23: ???
// - what happened here?
// - 20: v11.1 (?)
// - E5xx effect range is now ±1 semitone
// - 19: v11
// - introduces Arcade system
// - changes to the FM instrument format due to YMU759 being dropped
// - 18: v10
// - radically changes STD instrument for Game Boy
// - 17: v9
// - changes C64 volIsCutoff flag from int to char for unknown reasons
// - 16: v8 (?)
// - introduces C64 system
// - 15: v7 (?)
// - 14: v6 (?)
// - introduces NES system
// - changes macro and wave values from char to int
// - 13: v5.1
// - introduces PC Engine system in later version (how?)
// - stores highlight in file
// - 12: v5 (?)
// - introduces Game Boy system
// - introduces wavetables
// - 11: ???
// - introduces Sega Master System
// - custom Hz support
// - instrument type (FM/STD) present
// - prior to this version the instrument type depended on the system
// - 10: ???
// - introduces multiple effect columns
// - 9: v3.9
// - introduces Genesis system
// - introduces system number
// - patterns now stored in current known format
// - 8: ???
// - only used in the Medivo YMU cover
// - 7: ???
// - only present in a later version of First.dmf
// - pattern format changes: empty field is 0xFF instead of 0x80
// - instrument now stored in pattern
// - 5: BETA 3
// - adds arpeggio tick
// - 4: BETA 2
// - possibly adds instrument number (stored in channel)?
// - cannot confirm as I don't have any version 4 modules
// - 3: BETA 1
// - possibly the first version that could save
// - basic format, no system number, 16 instruments, one speed, YMU759-only
// - patterns were stored in a different format (chars instead of shorts) and no instrument
// - if somebody manages to find a version 2 or even 1 module, please tell me as it will be worth a lot
