|
|
Fork of the final open-source redream release (pre-relicense). Experimental
|
|
core with no HLE BIOS -- real BIOS files are required to boot games.
|
|
Flycast is recommended over this core for actual gameplay.
|
|
|
|
The libretro core sets appdir to the RetroArch system directory
|
|
(src/host/retro_host.c:216-217). boot.bin and flash.bin are loaded
|
|
directly from appdir (src/guest/rom/boot.c:17, src/guest/rom/flash.c:30).
|
|
|
|
The .info file declares paths as dc/boot.bin and dc/flash.bin, which means
|
|
RetroArch resolves them under {system_dir}/dc/.
|
|
|
|
boot.bin is validated against four known MD5 hashes at load time
|
|
(src/guest/rom/boot.c:25-30). If validation fails, the core logs a warning
|
|
but still attempts to run via HLE syscall hooks (bios.c:440-447).
|
|
|
|
flash.bin is read/write -- the core saves modified flash data back to disk
|
|
on shutdown (src/guest/rom/flash.c:197-199).
|
|
|
|
Boot ROM size: 2 MB (0x200000). Flash ROM size: 128 KB (0x20000).
