COSOM / SUPER JUNO’S WORLD / HD DEVELOPMENT PREVIEW
Super Juno’s World
New space-adventure artwork over the original game’s level foundation. A closer widescreen view makes Juno, creatures and terrain 50% larger on the 1920 × 1080 canvas. The browser preview begins in Yoshi’s Island 1.
Development preview · October 31, 2026. USB and Bluetooth gamepads now control the HD preview, with custom mapping for other HID layouts. The closer camera and fixed-size HUD remain in place. This remains a partial first-level preview; full gameplay, saves, audio, the campaign and complete animation coverage remain unfinished or unverified. Run animation is still under review.
New space-adventure art
New raster artwork replaces the visible hero, creatures, props, terrain and sky in the first-level preview. The closer widescreen view sits over the original world coordinates.
Original code and level data
The supplied cartridge remains the reference for level geometry, slopes, player physics, actor behavior, camera movement and activation. Converted browser code drives the preview.
A work in progress
The preview starts directly in the first level. World-map flow, audio, remaining forms and actor paths, saves and full-campaign verification are still outstanding.
