Commander X16

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.

Usage:

• 
  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.
