cc65 - a freeware C compiler for 6502 based systems
d602572bbe
Files created by my programs running under sim65 had really weird permissions: --w-r--r-x 1 ppelleti staff 19 Aug 16 23:22 json.test.print.tmp So, for example, my program running under sim65 was not able to read the file it had just written. This is because the third argument to open (mode) was not being specified in paravirt.c, so it was just picking up random crud off the stack to use as the mode. I added a mode of 0666, and now my program runs correctly. |

cc65 is a complete cross development package for 65(C)02 systems, including a powerful macro assembler, a C compiler, linker, librarian and several other tools.
cc65 has C and runtime library support for many of the old 6502 machines, including
- the following Commodore machines:
- VIC20
- C16/C116 and Plus/4
- C64
- C128
- CBM 510 (aka P500)
- the 600/700 family
- newer PET machines (not 2001).
- the Apple ][+ and successors.
- the Atari 8 bit machines.
- the Atari 2600 console.
- the Atari 5200 console.
- GEOS for the C64, C128 and Apple //e.
- the Bit Corporation Gamate console.
- the NEC PC-Engine (aka TurboGrafx-16) console.
- the Nintendo Entertainment System (NES) console.
- the Watara Supervision console.
- the VTech Creativision console.
- the Oric Atmos.
- the Oric Telestrat.
- the Lynx console.
- the Ohio Scientific Challenger 1P.
The libraries are fairly portable, so creating a version for other 6502s shouldn't be too much work.
