Abdessamad Derraz fcfc10b985 chore: re-profile XRoar 1.12.1 
Refs moved to the 1.12.1 tree and its src/ layout. The new rom.c table names the crc32 of nine ROMs, two of which the code checks.

notes: |
XRoar by Ciaran Anscomb emulates Dragon 32/64, Tandy CoCo 1/2/3,
MC-10, Alice, and clones (MX-1600, CP-400, Dragon 200-E, Deluxe CoCo).
ROM files are searched in a configurable rompath directory with automatic
extension appending (.rom, .ROM, .dgn, .DGN). Batocera sets rompath to
/userdata/bios/xroar/.
The romlist mechanism defines fallback filenames per ROM slot. Each machine
type has a default romlist that tries filenames in priority order. CRC32 is
computed for loaded ROMs and matched against known-good values for breakpoint
and feature detection, but mismatches do not prevent loading. A
ROM metadata table (src/rom.c) maps CRC32 and size to a description, the
debugger symbol table and, for a file inserted as a cartridge, the cartridge
type. It names images, it does not accept or reject them.
Machine selection: Batocera maps system names to default machines via
xroarGenerator.py (mc10 -> mc10, dragon64 -> dragon64, others -> coco2bus).
