About Spectrum Next Layer 3 Hardware Tilemap Editor

Spectrum Next Layer 3 Hardware Tilemap Editor is in development by Gary Pinkett.

This browser tool is being built for ZX Spectrum Next developers creating Layer 3 hardware tilemaps, tilesets, palettes, collision masks and object data for NextBuildStudio and Boriel BASIC projects. It specfically targets the Next hardware tilemap layer, rather than a software tilemap.
