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.

|
|
|
Saturn BIOS search order:
|
|
1. {system}/sega_101.bin
|
|
2. {system}/mpr-17933.bin
|
|
3. {system}/saturn_bios.bin
|
|
First file found with exact 512 KiB size wins. No HLE fallback for IPL.
|
|
|
|
CD Block LLE: optional low-level CD drive emulation. Scans {system}/cdb/
|
|
for any 64 KiB file. Falls back to HLE when disabled or no ROM found.
|
|
Known versions in upstream db: 1.04, 1.05, 1.06.
|
|
|
|
ROM cartridges: KoF95 and Ultraman shipped with physical ROM carts. The
|
|
core auto-detects required cartridge from its game database.
|
|
|
|
Addon cartridges: 1M/4M DRAM expansion handled via core option (no files).
|
|
|
|
Upstream uses XXH128 hashes for ROM identification only, not validation.
|
|
All file loading validates size only.
