bios_mode: agnostic (profile) and agnostic: true (file) for
emulators that accept any valid BIOS without specific filename.
find_undeclared_files skips agnostic entries, pack extras scan
includes all matching DB files by path prefix + size criteria,
resolve_local_file has agnostic fallback with rename README.
applied to pcsx2, lrps2 (bios_mode), melonds dsi_nand (file).
aliases must be same-SHA1 alternative names, not distinct files.
pcsx2: 164 different BIOS dumps are separate DB entries, not aliases.
melonds: 6 regional NAND dumps are separate DB entries, not aliases.
also cleans pcsx2 non-standard fields, fixes display_name.
Every profile now has:
- profiled_date: date of source code analysis
- core_version: version from libretro-core-info .info files
- display_name: human-readable name from .info files
260/260 profiles complete. 294/294 libretro cores covered.
Standalone emulators (cemu, rpcs3, xemu, vita3k) versioned manually.
- Added profiled_date field to all 204 existing profiles for update tracking
- Created 56 alias profiles for cores that share BIOS with a parent
(e.g., mednafen_psx -> beetle_psx, fbalpha2012 -> fbneo)
260 total profiles covering all 294 libretro cores (204 unique + 56 alias).
