Core War

This is a proof of concept of a Core War VM for the X16.
It implements all ICWS'88 opcodes (plus a couple extra); as proof of concept it runs many of the "historical" redcode programs from that period. It has a PETSCII arena view which follows colorized redcode programs. Up to 8 programs may run at a time, and each may have up to 8 processes.
It does not handle operand expression math.
The project is here:

I just spent a morning writing a kind of test framework for debugging the opcode handling.
I just re-learned that C functions on the X16 need to be relatively simple; the fewer params passed, the better.
No worries.

I've been thinking about different ways of using banked RAM for the ARENA.
(1) Just slop it into banks. This is probably what I'd do. Just occupy as many banks as I want, and have appropriate boundary checking etc.
(2) Use Bank 1 as an index. If I keep the core size to <= 8192, then Bank 1 can indicate which bank each cell is located in. This is more or less a way of skipping one operation in #1 above, but it creates an indirect dereference and in the end it doesn't sound like it's worth the effort. I mean, if the relationship is a simple div to begin with, why store an indirect ref in a table?

I've been thinking about how to EDIT core warriors. I wonder if I can use our text-editor utility...

So far, I've debugged MOV in two modes, ADD (and SUB) in three modes, and started on MUL and DIV.
It's slow going.

It depends which c compiler you use.

Added a CLI to help me debug a bit better.

What is a CLI?

Command Line Interface.

CLI stands for Command-Line Interface.
