Actually that's a good question - why are the cases 0x08 and 0x09?
I figured it had something to do with pmode being a signed short and the
playstation's byte ordering being different.

The only explanation I could come up with is that:
hex        bin     dec
0x08 = 1000 = 0
0x09 = 1001 = 1
and that the playstation interprets the most significant bit as a positive
number.

Anyone care to explain/correct?

Thanks,
Rad.
