Small projects in 6502/6510 assembly targeting the ACME assembler for Commodore 64. This is intended as a reference for more complicated projects.
You will need to install the ACME assembler and Vice C64 emulator.
On OSX, you can either use Homebrew to install these dependencies, or the DUST command line utility.
On Linux, use the AUR on Arch-based distros. Ensure contrib
is added to your sources.list on Debian/Ubuntu-based distros.
On Windows 10 WSL2 without GUI app support, install the Windows version
of Vice and add the \bin folder to your PATH env variable. Add export C1541=c1541.exe and export X64=x64sc.exe to an appropriate rc file for
your WSL2 distro.
Follow instructions at http://brew.sh/ if you do not have Homebrew installed, then:
brew update
brew install acme vice
Follow instructions at http://dustlayer.com/c64-coding-tutorials/2013/2/10/dust-c64-command-line-tool.
To build and run the project, ensure you have acme, c1541, and x64 on
your path.
Run make [project], where [project] is one of:
helloworldex_interrupts
There are several tiny projects in this repository, each an exercise in some aspect of programming in assembly for the C64.
This project shows how to start a program, store bytes in RAM, clear the screen, show characters on the screen, use registers, loop, and complete a subroutine.
This project shows how to disable the various interrupts, enable raster interrupts for a specific line, use the interrupt vector to override the system interrupt subroutine, and define a custom interrupt subroutine.
This project shows how to render tiles consisting of NxN characters, coloured per tile.
