        "notes": "Ymir is a Sega Saturn emulator by StrikerX3. The libretro port by\nwarmenhoven wraps the shared ymir-core library (PR #746, not yet merged).\nNo .info file exists in libretro-core-info.\n\nStandalone: scans configured directories recursively for files matching\nthe expected size. No specific filenames required. Identifies known ROMs\nby XXH128 hash from an internal database (19 IPL variants, 4 CD Block\nversions, 2 ROM carts). Unknown files are accepted if size matches.\n\nLibretro: searches {system}/sega_101.bin, mpr-17933.bin, saturn_bios.bin\nin order. First file found with exact 512 KiB size wins.\n\nBatocera standalone: configgen maps IPLROMImages to /userdata/bios,\nCDBlockROMImages to /userdata/roms/saturn/cdb/, ROMCartImages to\n/userdata/roms/saturn.\n\nNo HLE fallback for IPL ROM. CD Block LLE is optional and falls back to\nHLE when disabled or no ROM found. Known CDB versions: 1.04, 1.05, 1.06.\n\nROM cartridges: KoF95 and Ultraman shipped with physical ROM carts.\nAuto-detected from game database when loading a disc.\n\nAddon cartridges: 1M/4M DRAM expansion handled via core option (no files).\n\nXXH128 hashes used for ROM identification only, not validation.\nAll file loading validates size only.\n",
