emul
This is an emulator for a virtual machine that is suitable for running Collapse OS. The goal of this machine is not to emulate real hardware, but rather to serve as a development platform. What we do here is we emulate the z80 part, the 64K memory space and then hook some fake I/Os to stdin, stdout and a small storage device that is suitable for Collapse OS's filesystem to run on.
Through that, it becomes easier to develop userspace applications for Collapse OS.
We don't try to emulate real hardware to ease the development of device drivers because so far, I don't see the advantage of emulation versus running code on the real thing.
Usage
First, make sure that the libz80 git submodule is checked out. If not, run
git submodule init && git submodule update.
The Makefile in this folder has multiple targets that all use libz80 as its
core. For example, make shell will build ./shell, a vanilla Collapse OS
shell. make zasm will build a ./zasm executable, and so on.
See documentation is corresponding source files for usage documentation of each target.
