Abdessamad Derraz b3b3880c19 chore: say which repository each source_ref cites
Profiles that read two repositories, a libretro port and its upstream,
now prefix each citation with source or upstream, decided by which tree
carries the cited value at its pin. The emulator pages use the word to
tell libretro glue, emulator code as the port carries it, and the
upstream emulator apart.

notes: |
Fork of the last GPLv3 release of redream (inolen) before it went closed-source.
The core has HLE bootstrap -- when boot.bin is missing, bios_invalid_instr()
traps at PC=0x0 and calls bios_boot(), which loads IP.BIN and 1ST_READ.BIN
directly from disc, sets up syscall vectors, and starts execution at 0xac008300.
The fork sets appdir to the RetroArch system directory root
(retro_host.c:216-217), unlike the upstream which appends /dc
(upstream retro_host.c:196-198). The .info still declares dc/ prefix paths
matching the upstream, not this fork.
boot.bin is validated against four known MD5 hashes (boot.c:25-30).
Validation failure logs a warning but the core continues via HLE.
flash.bin is read/write. If missing, bios_validate_flash() resets all
partitions to defaults. Saved back to disk on shutdown (flash.c:197-199).
