The 0x8000 alignment in DirectoryBlob is needed for Wii disc group encryption,
but for GC/Triforce it inflates file offsets unnecessarily. Use 0x20 alignment
for Triforce (matching original disc layout) while keeping 0x8000 for GC due
to DTK audio streaming requirements.
On Triforce games with many files, the inflated offsets can land in the
AMMediaboard DIMM memory range (0x1F000000-0x1F800000). Reads from that
region return SRAM data instead of disc data, causing the game to hang.
Skip the DIMM range when assigning per-file data offsets if any portion of
the file would overlap [0x1F000000, 0x1F800000).
Use the existing system reference instead of Core::System::GetInstance(),
and calculate the phase 2 scheduling delay from GetTicksPerSecond()
instead of hardcoding 50000 ticks.
The legacy Execute1 path (offset=0, length=0) was using Write_U32
(big-endian) to write the "TEST OK" status string. However, the PPC
display code in segaboot reads this buffer with lwz followed by manual
bswap32, so the data must be stored in little-endian. Use Write_U32_Swap
to match the other two TestHardware paths.
Implement the MediaBoard commands and response protocol needed for
the segaboot NETWORK TEST to pass:
- TestHardware (0x0301) two-phase response via CoreTiming: phase 1
echoes test_type with 0x80 acknowledgment flag, phase 2 sends
result with testStatus=2 and checkProgress=100
- GetNetworkConfig (0x0104) with trinetcfg.bin read intercept
- Separate Execute1/Execute2 last-response buffers to prevent
cross-clobber on the shared s_media_buffer
- Generic 0x80xx cleanup command acknowledgment
- Network config persistence for SET IP ADDRESS
