feat: shared groups, scraper subdir prefixes, arcade + emulator profiles
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.

# Redream — Sega Dreamcast (libretro)

# ref: libretro/redream, docs.libretro.com/library/redream

|
|
|
# Uses dc/boot.bin and dc/flash.bin (different names from Flycast)
|
|
|
|
|
# Same BIOS data as Flycast's dc_boot.bin / dc_flash.bin
|
|
|
|
|

|
|
|
|
|
# doc vs source: docs list boot.bin md5 e10c53c2f8b90bab96ead2d368858623
|
|
|
|
|
# which matches dc_bios.bin in the repo. Flycast uses dc_boot.bin (same
|
|
|
|
|
# data, 2 MB) while Redream calls it boot.bin. The flash.bin is identical
|
|
|
|
|
# across both cores.
