z80 assembler

This is probably the most critical part of the Collapse OS project. If this app can be brought to completion, it pretty much makes the project a success because it ensures self-reproduction.

Running on a “modern” machine

To be able to develop zasm efficiently, libz80 is used to run zasm on a modern machine. The code lives in emul and ran be built with make, provided that you have a copy libz80 living in emul/libz80.

The resulting zasm binary takes asm code in stdin and spits binary in stdout.
