Closes #43 FBNeo and Kronos expect BIOS archives in core-specific subdirectories (system/fbneo/, system/kronos/). RetroArch firmware check uses .info paths which include these prefixes, so files at root show as Missing. Add archive_prefix field to emulator profiles. The pack code now places archive copies in the prefixed subdirectory while keeping root copies for cores that expect them there (e.g. Geolith for neogeo.zip).

notes: |
|
|
Kronos is a Sega Saturn and ST-V arcade emulator by FCare, forked from
|
|
Yabause. Requires OpenGL 4.3 compute shaders.
|
|
|
|
Saturn BIOS search order:
|
|
1. {system}/kronos/saturn_bios.bin
|
|
2. {system}/saturn_bios.bin
|
|
3. {system}/sega_101.bin
|
|
4. {system}/mpr-17933.bin
|
|
First file found wins. Real BIOS required (HLE deprecated, only available
|
|
via kronos_force_hle_bios core option for debugging).
|
|
|
|
ST-V BIOS: {system}/kronos/stvbios.zip or {system}/stvbios.zip
|
|
MAME-style ZIP containing region-specific EPROMs. Kronos picks the best
|
|
match by game region and kronos_stv_favorite_region core option (EU/US/JP/TW).
|
|
|
|
ROM cartridges for KOF95 and Ultraman are auto-detected via game database
|
|
(db.c) and loaded from system_dir when the corresponding game is running.
