What each layer does, how the editor is used, and the table of what is and is not implemented.

A StarCraft and Brood War map editor that runs in a browser tab, built in homage to StarEdit, SCMDraft 2 and StarForge.

It opens real .scm, .scx and .chk files, draws them with the game's own tileset and unit graphics, and writes archives the game will play. Sections and archive members it does not understand are copied through untouched, so a map only loses what you deliberately change.

Beta. Nothing here has shipped a campaign yet. Keep backups of maps you care about, and check anything important in-game before you rely on it.
