ROM functions used:
|
||||
0x8000 dsp reset
|
||||
0x8078 wait for CMBH & 0x8000
|
||||
0x807e wait for DMBH & 0x8000
|
||||
0x808b dump DRAM/IRAM to mainmem
|
||||
0x80b5 boot new ucode
|
||||
0x80bc boot new ucode without ACC clearing by ROM
|
||||
|
||||
For the rest, this ucode is just calling the last few instructions
|
||||
from huge functions in ROM - some kind of obfuscation?
