- Xevious (U): Promoted from _wip/NROM/Xevious (U)/ to NROM/Xevious (U)/
- Pass 3 complete: 34.5% code coverage, 143 semantic entry points,
4 named data tables, ~20 semantic ZP aliases
- NROM mapper 0, 32 KB PRG, 8 KB CHR, horizontal mirroring
- Zanac (U): Promoted from _wip/UNROM/Zanac (U)/ to NROM/Zanac (U)/
- Pass 3 complete: 34.5% code coverage (bank 7 only), 133 semantic
entry points, 26 named data tables, 14 semantic ZP aliases
- UNROM mapper 2, 128 KB PRG (8 banks), no CHR
- Bank 7 fixed at CPU -; banks 0-6 switchable at 000-
- Bank 7 assembled separately as prg.07.s with .org
Both projects build byte-identical. Updated root README.md inventory,
per-project details, and WIP.md accordingly.
Move Zanac (U) to UNROM/ mapper directory
Zanac (U) is a UNROM (mapper 2) game, not NROM (mapper 0). Move it to
the correct mapper directory and update README.md and WIP.md references
accordingly. Update project counts in WIP.md (857->856 total, UNROM
98->97 projects).
Promote Mermaids of Atlantis (U) from _wip/ to MAPPER8/
Additional cleanup of Mermaids of Atlantis
