        "notes": "Fork of the last GPLv3 release of redream (inolen) before it went closed-source.\nThe core has HLE bootstrap -- when boot.bin is missing, bios_invalid_instr()\ntraps at PC=0x0 and calls bios_boot(), which loads IP.BIN and 1ST_READ.BIN\ndirectly from disc, sets up syscall vectors, and starts execution at 0xac008300.\n\nThe fork sets appdir to the RetroArch system directory root\n(retro_host.c:216-217), unlike the upstream which appends /dc\n(upstream retro_host.c:196-198). The .info declares dc/ prefix paths, the\nlayout the upstream reads.\n\nboot.bin is validated against four known MD5 hashes (boot.c:25-30).\nValidation failure logs a warning but the core continues via HLE.\n\nflash.bin is read/write. If missing, bios_validate_flash() resets all\npartitions to defaults. Saved back to disk on shutdown (flash.c:197-199).\n",
