Oliver Schmidt a2a4868825 Added HGR and DHGR slide show programs. 
The DHGR program is sort of a hack as it first switches to double (aka 80 col) text mode to prepare for double graphics mode. Therefore only one additional soft switch access is necessary after using TGI to generally switch to hires.

Build Status

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.
