Demos for the Commodore C64 written in C++ 20 using Clang for 6502/6510, C using CC65 and 6502 assembler using ACME.
 |
- Animated sprites
- Scrolling starfield
- Raster interrupt handling
- SID music
- NMI digi sample playback
- For development and building, please install the VS64 extension for Visual Studio Code. (https://marketplace.visualstudio.com/items?itemName=rosc.vs64)
- For best performance, switch the build mode to "release" to turn on code optimization. This makes a significant difference!
- To edit the sprites and charsets, the tools CharPadPro and SpritePadPro need to be installed (Windows only)
- For C++, the LLVM-MOS development environment needs to be installed. (https://github.com/llvm-mos/llvm-mos-sdk)
- For plain C, the CC65 compiler needs to be installed. (https://cc65.github.io)
- For 6502 assembler, the ACME Cross-Assembler needs to be installed. (https://sourceforge.net/projects/acme-crossass)
Not covered yet, but fyi - VS64 also supports the Kick Assembler toolkit. Porting the ACME version of the demo should be very straight forward to do. (http://theweb.dk/KickAssembler)
For convenience, simplified versions of the demo for the CC65 compiler and the ACME assembler are included.
