The weird thing is I forked Freepascal to add an architecture of A VM I had written. It wasn't really useful to anyone else, but every now and again it earns a star from a random passer by.
The changes were very minor. My VM was an 8-bit Avr. I just needed to add a profile for an imaginary microcontroller with no peripherals, 64k ram and 64k words ROM.
So what was on GitHub is an unmodified fork, 16 years behind upstream, and has acquired 20 stars. 8 in the last year.
