About This File
This is a template for ROM based assembly programs that you are free to use or continue upon.
It's made for the CA65 assembler.
- Create your program code as normal. Of coarse, you need to place all variables in RAM and avoid any self modifying code.
Include the file kernal.inc. This will:
- Create jump vectors for all "public" KERNAL function, and
- Set the IRQ vector in $fffe-ffff, so that the KERNAL interrupt handler is called.
The file example.s is a small hello world test.
The project is built with build.sh.
The file example.cfg contains the memory segment settings needed by the assembler/linker.
The source code is also available on Github:
