States taken from System Menu 257 (3.1U)
Types
| State number | action | next states |
|---|---|---|
| 0 | prints out status flags ("No Disk", "Drive Reset", "Wait Spinup", "Boot from Cache"), delay?, enable waiting-for-disk? | 2, 52 |
| 1 | delay | 2 |
| 2 | delay, enable waiting-for-disk?, DVDResetAsync | 3 |
| 3 | bs2_issue_dvd_command, delay, __DVDGetCoverStatusAsync, create cache.dat? | 4 |
| 4 | ReadDriveInfo via cache.dat or DVDInquiryAsync | 5 |
| 5 | wait for dvd command to finish, update cache.dat if necessary, setup 800030E6 [16bit] based on drive info and console type | 8 |
| 6 | DVDDownRotationAsync | 7 |
| 7 | bs2_issue_dvd_command? | 8 |
| 8 | Read 0x20 bytes of disk id [from cache.dat or disk via DVDReadDiskID] | 9 |
| 9 | wait for dvd command to finish, update cache.dat if necessary, copy the 0x20 byte long disk id to 0x80000000.
if [disk_id + 0x18] is 0x5d1c9ea3, and the [disk_id + 0] is not 'RAAE', treat as a wii disc. otherwise, if [disk_id + 0x1c] is 0xc2339f3d, treat as gamecube disk otherwise, the disk type is unknown |
gamecube disk = 11, wii disk = 15, unknown = 54 |
| 10 | ||
| 11 | if not waiting for a disk, exit to state 50
if waiting, disable the waiting-for-disk and check streaming [0x80000008] if streaming and no streaming buffer size defined [0x80000009], set to size 10 if streaming, setup via __DVDAudioBufferConfig go to state 12 |
12, 50 |
| 12 | wait for DVD command to finish | 13 |
| 13 | async unencrypted 0x2000 byte dvd read | 14 |
| 14 | wait for DVD command to finish
once finished, check game region |
region ok = 50
region not match = 54 |
| 15 | unknown check can switch to state 70
read 0x20 bytes from disk (game toc?) |
16 |
| 16 | wait for dvd command to finish, update cache.dat if necessary | 17 |
| 17 | read partition info from disk | 18 |
| 18 | wait for dvd command to finish, update cache.dat if necessary
go through the game partition, making note of those of type 0 and 1 |
19 |
| 19 | read 0x2000 bytes from disk | 20 |
| 20 | wait for dvd command to finish, update cache.dat if necessary
if 0xc3f81a8e not found at the end of read block, go to state 54 if region check fails, go to state 54 if BS2IsValidDisc check fails, go to state 54 if booting from cache, go to state 37 if there's a partition of type 1, go to state 21 if there's a partition of type 0, go to state 37 otherwise, go to state 54 |
