Sprite Forge 64

v0.10 · doodle v1.17
Sprite Forge 64 workbench SF64 Doodle pad
VIC-II sprite foundry. Underlay + hi-res ink overlay, shared-register color law, animation clips, frame reflow — the .sf64 pipeline the game eats directly. The doodle pad is its touch-first pocket sibling: sketch on the couch, import at the bench.

World Forge 64

v0.12
World Forge 64 with the neon city demo
Scrolling world builder. The layer cake: raster-split parallax bands, a forgeable 256-glyph alphabet, auto-tiling, collision lens, sprite-scale ghost — and a one-click .prg test drive that proves the drift on real iron.

Groove Forge 64

v0.7
Groove Forge 64 sequencer
SID techno sequencer. Sixteen-step patterns across three voices, swept-triangle kick, PWM breathe, filter LFO — chain the arrangement, preview in the browser, then export the byte-true .prg: the real SID is the truth.

Screen Forge 64

v0.9
Screen Forge 64 bitmap editor
Bitmap & scenery painter. 160×200 Koala multicolor with the hardware color law enforced live, reference-art staging and capture, plus CHAR mode for scroll-legal backgrounds — exports .koa, .charjson and a self-showing .prg.
