/* **** */


seems to be several distinct blocks of data...

0x000000 -- 0x0005ff
0x000600 -- 0x007dff
0x007e00 -- 0x008dff
0x008e00 -- 0x0096ff
0x009700 -- 0x200000


/* **** */

looking at what seems to be the header...

0xxxxxxxxx: ef ff zz zz 1f zz zz zz f0 zz zz zz ef ff df zz 50 zz zz de 86 d0 82 e7 10 00 20 41 83 07 0f e3

many entries seem to follow a distinct format...

where valid hex bytes remain consistent...  zz are bytes that consistently vary.

/* **** */

suggested offset at 4... with xor 0x1F3E7CF8
suggested length at 8... with xor 0xF0C1A367
