What is verified
A 16K MSX2 cartridge boots under C-BIOS and draws the canonical Orchard in SCREEN 5. Palette upload, VRAM fill/copy and the tile blitter are operational, with the complete map retained in ROM.

Not playable yet. Pip, scrolling, physics, collision, audio, the front end, HUD, scoring and end cards remain in development.
Why MSX2
The V9938 allows true 16×16 metatiles and sixteen simultaneous colours chosen from 512, avoiding the geometry squeeze and colour compromises of the earlier MSX1 SCREEN 2 experiment.
Release truth
This page documents active engineering progress. The artwork above is period-inspired package concept art; it does not claim a final cassette edition. The current technical target is a cartridge build.
Next engineering milestones
- Horizontal scrolling so the full 320-pixel-wide Orchard is reachable.
- Pip as an MSX2 hardware sprite, followed by movement physics and collision against the shared map.
- Native audio implementation from the authored music and sound tables.
- Deterministic gameplay acceptance through the openMSX debugger before any release claim.
