js-dos v8.3.8 (loaded from CDN) calls bundleUpdateConfig to re-add
.jsdos/jsdos.json into the downloaded bundle. This fails on our
bundles because the WASM libzip _zipfile_add returns non-zero.
Since we can't fix js-dos's internal WASM code, we remove the .jsdos/
directory from bundles entirely. This means bundleConfig() returns null,
no editor config is set, and bundleUpdateConfig is never called.
Downside: games start with js-dos's default dosbox.conf (no custom
CD mounts or autoexec). The game files are on C:\ and the user can
type the executable name. Added autoStart + countDownStart=0 to
auto-skip the config UI.
The config API endpoint (/api/games/{id}/config) is kept for future
use where we can inject config after the emulator starts.
Dostalgia test
A nostalgic DOS game hub. Upload your old DOS games, scrape artwork, and play them directly in the browser via js-dos (WebAssembly DOSBox).

Development (without Docker)
Terminal 1 — Frontend dev server:
cd frontend && npm install && npm run dev
Terminal 2 — Quarkus dev server:
mvn quarkus:dev
Open http://localhost:5173 (Vite proxies API calls to Quarkus on port 8765)
Production build (local)

Architecture
- Backend: Quarkus (Java 21, JAX-RS) — ~5 REST resource classes, zero database
- Frontend: Svelte 5 SPA with hash-based routing
- Emulation: js-dos v8 loaded from CDN, runs DOSBox in WebAssembly
- Storage: JSON-per-game under
/data/games/{id}/game.json
