MOSpeed Web edition

What is MOSpeed - Web edition?

This is an experimental web version of MOSpeed, an optimizing cross compiler for Commodore BASIC V2. It can compile BASIC V2 source code into executables for the C64, the VIC20 and the Commander X16. It takes either text or PRG files as input.

For convenience, the configuration will be saved in a cookie on your computer at each compile. Depending on how many files you compile in one go and on your configuration, you'll either get a PRG file or a ZIP file after the compilation.

Source code and compiled files will only be stored during the compilation and will be deleted once your download starts.

Please note: This server runs on a Raspberry Pi 4. So please don't expect great performance out of it.
MOSpeed will most likely run much faster on your local PC.
