/* writes the following sequence before how to play
each level has a different sequence written before it, size of sequence doesn't seem directly connected to level size (unlike the reads)
so it's probably compressed somehow as well as scrambled? 68k doesnt know in advance how big each lot of data is either, it only stops
writing when it gets a difference response from the MCU.
(puzzli2 left, puzzli2 super right) (Stored at 153ea - 15411 in puzzli2s program) results read back are the same, the data for level 1 is at f916, there does seem to be some form of pattern every 16 bytes?
