All sound registers are accessed through only two physical registers.

This is the index register. You write the desired register number here.
9030:
-----
This is the data register. Data written here is stored in the register
pointed to by the above index register.
ok... but
00h - 07h : Custom instrument registers -> This mean $9000-$9007 ?????
10h - 15h : ffffffff -> mean $9010 - $9015 ???
30h - 35h : iiiivvvv -> $9030-$9035 ???
I can't understand this
