retroarch.yml regenerated by libretro_scraper with CORE_SUBDIR_MAP
(dc/, np2kai/, keropi/) and shared groups (fuse, kronos, ep128emu,
quasi88, np2kai, keropi). common.py dedup by (name, destination)
to allow same file at flat + subdirectory paths.
ep128emu shared group added for Enterprise system.
RetroArch pack grows from 398 to 428 files.
ref: each subdirectory traced to original emulator source code —
see platforms/README.md and _shared.yml comments.
shared groups in _shared.yml: np2kai, keropi, quasi88, kronos, ep128emu
with source references for each subdirectory requirement.
libretro_scraper: CORE_SUBDIR_MAP applies subdirectory prefixes at
generation time (np2kai/, keropi/, dc/). EXTRA_SYSTEMS adds QUASI88.
SYSTEM_SHARED_GROUPS injects includes for kronos/np2kai/keropi.
new BIOS: CPS3 (23 ZIPs), Cannonball OutRun (40 ROMs), PCem PC BIOS
(73 files), VICE Commodore ROMs, Spectrum ZIPs, dc_bios.bin, X1 fonts.
new emulator profiles: redream, melonds_ds, lrps2 with doc vs source
notes. platforms/README.md documents shared groups architecture.
