This is not supposed to be a full-flavoured port of Rittle, but only demo for playing with the core functionality. It runs under Windows and its speed is a few times lower than the PIC32 implementation, but still, it could be a useful tool for initial understanding of the language. The core functionality is full.
Port limitations: The IFS: device is emulated in an external file. SD card support is currently missing. Line editing functionality in RIDE and in the command line is reduced. All PIC32-related stuff is missing.
