# Javatari 0.91 (8bitworkshop fork), frozen The `vcs` platform in the IDE (`VCSPlatform`, src/platform/vcs.ts) loads `javatari/javatari.js` and drives Javatari's own screen and console UI. These files are the prebuilt bundle from the javatari.js fork at commit 113cd57 (`release/javatari/`). That build carries the hooks the IDE calls: `debugEval`, `getCPUState`, `saveControlsState`, `getOpcodeMetadata`, and `Monitor.getDisplayParameters`. The `javatari.js` submodule now tracks upstream v4 on the `v4-core` branch. Its sources don't have these hooks and can't rebuild this bundle, so don't replace it with a `grunt` build. The submodule supplies only `release/core/javatari-core.js`, the headless core behind `vcs.jt4` (src/machine/vcs.ts). Javatari is copyright Paulo Augusto Peccin, under the AGPL v3; see `license.txt`.
