I put my NES related Open Source projects here.
I programmed neslisp which can be found at http://sourceforge.net/projects/neslisp/ I also ported it to the Commodore 64, here's the link : http://sourceforge.net/projects/neslispc64/ The C64 version was made with cc65 (http://www.cc65.org) and can be easily ported to the NES natively but has memory area overflows.
There's also ados-nes at http://sf.net/projects/ados-os-nes which is my OS ported to the NES with lots of useful features for hardware hacking, the "massive" x86 ados OS is at http://sf.net/projects/ados-os
Then for fun, I made a Super Mario Bros. codebase with 2 levels, it has a windows version and was made with Python and Pygame (http://pygame.org). Here it is : http://sourceforge.net/projects/brothersinarms/
I also wrote a Final Fantasy II clone in plain Java, the source code is at :https://sourceforge.net/projects/angelsdestinyrpg/
