Commodore, Thomson, PC, Acorn), FBNeo (CPS3 redearthn/sfiii2h),
and QEMU variants. Sources: Asimov mirror, MAME chip extraction,
86Box, Theodore, XRoar upstream, official QEMU repo.
Fix cross-reference in verify.py to group archived files by archive
unit instead of reporting individual ROMs as missing. Add path-based
fallback for descriptive names. Update generate_pack.py extras to
use archive name for resolution. 6 new E2E tests.
