notes: |
|
|
Ymir is a Sega Saturn emulator by StrikerX3. The libretro port by
|
|
warmenhoven wraps the shared ymir-core library (PR #746, not yet merged).
|
|
No .info file exists in libretro-core-info.
|
|
|
|
Standalone: scans configured directories recursively for files matching
|
|
the expected size. No specific filenames required. Identifies known ROMs
|
|
by XXH128 hash from an internal database (19 IPL variants, 4 CD Block
|
|
versions, 2 ROM carts). Unknown files are accepted if size matches.
|
|
|
|
Libretro: searches {system}/sega_101.bin, mpr-17933.bin, saturn_bios.bin
|
|
in order. First file found with exact 512 KiB size wins.
|
|
|
|
Batocera standalone: configgen maps IPLROMImages to /userdata/bios,
|
|
CDBlockROMImages to /userdata/roms/saturn/cdb/, ROMCartImages to
|
|
/userdata/roms/saturn.
|
|
|
|
No HLE fallback for IPL ROM. CD Block LLE is optional; falls back to
|
|
HLE when disabled or no ROM found. Known CDB versions: 1.04, 1.05, 1.06.
|
|
|
|
ROM cartridges: KoF95 and Ultraman shipped with physical ROM carts.
|
|
Auto-detected from game database when loading a disc.
|
|
|
|
Addon cartridges: 1M/4M DRAM expansion handled via core option (no files).
|
|
|
|
XXH128 hashes used for ROM identification only, not validation.
|
|
All file loading validates size only.
