notes: |
|
|
Fork of the last GPLv3 release of redream (inolen) before it went closed-source.
|
|
The core has HLE bootstrap -- when boot.bin is missing, bios_invalid_instr()
|
|
traps at PC=0x0 and calls bios_boot(), which loads IP.BIN and 1ST_READ.BIN
|
|
directly from disc, sets up syscall vectors, and starts execution at 0xac008300.
|
|
|
|
The fork sets appdir to the RetroArch system directory root
|
|
(retro_host.c:216-217), unlike the upstream which appends /dc
|
|
(upstream retro_host.c:196-198). The .info still declares dc/ prefix paths
|
|
matching the upstream, not this fork.
|
|
|
|
boot.bin is validated against four known MD5 hashes (boot.c:25-30).
|
|
Validation failure logs a warning but the core continues via HLE.
|
|
|
|
flash.bin is read/write. If missing, bios_validate_flash() resets all
|
|
partitions to defaults. Saved back to disk on shutdown (flash.c:197-199).
