I tried the Python and SQLite modules on desktop Chrome and got similar errors for both. For Python:

Error: CPython engine could not load (Failed to fetch dynamically imported module: https://sonistellar.com/lab/vendor/pyodide/pyodide.mjs). Check the network, then close this tile and re-boot to retry. — press reset or back to menu

For SQLite:

Error: SQLite engine could not load (GET https://sonistellar.com/lab/vendor/sqlite/sql-wasm.js -> HTTP 404). Check the network, then close this tile and re-boot to retry. — press reset or back to menu

FreeDOS loaded though, Snake and Tetris were fun!
