2) If a pattern or song does not exist, its MSB pointer will = 0, which is an illegal pointer address. Since
there will be no data for this pattern, it is skipped, i.e., if pattern 04 is empty, pattern 05's data follows
after pattern 03's data.
3) There can be no gaps in the data. Pattern 01's data must follow directly after pattern 00's data, etc.
4) Locations 2CDH-2CEH (start of free memory) and 2D1H-2D2H (length of free memory) must be kept
valid.
5) Song 99 MUST exist. This means that at least an empty song (03H 00H FFH) must be at the end of
memory, and song 99 must point to it.
6) It is suggested that all DON'T CARE data be left in the state that it is received in, although these
locations can be replaced with zeroes.
PATTERN DATA FORMAT
The following is the format of each pattern, starting with the address pointed to byte the absolute pointer to
the pattern (offset by 8200H):
00H
LSB of number of bytes in pattern, including header.
01H
MSB of number of bytes in pattern, including header.
