zpz: An Amstrad CPC emulator frontend written in zig using https://github.com/floooh/chips

zpz is an emulator frontend (basically just some zig glue code) that uses Floooh's chip library to emulate an Amstrad CPC 6128.

I encourage you to check out https://github.com/floooh/chips for a very well made, clean and understandable CPC emulator code base.

Demo

The emulator is accessible in your browser here: http://cpc.novidee.com.

Build

First clone the zpz repository:

git clone git@github.com:jdmichaud/zpz.git

Then, in zpz folder, initialize the chips submodule:

git submodule init
git submodule update

Note that this will checkout a custom version of the chip folder supporting 2 disks for the CPC.

Then to build the solution:

zig build

For best performance:

zig build -Doptimize=ReleaseSafe

Usage

To launch:

./zig-out/bin/zpz6128

To load one or two disks, pass the dsk file path in the command line:

./zig-out/bin/zpz6128 /path/to/some.dsk /another/path.dsk

Build for the web

In order to generate a wasm file do:

zig build wasm -Doptimize=ReleaseSmall

Then serve the web folder:

cd web
python3 -m http.server

The release flag is mandatory. Without it, your browser will complain of too much local variables. The release flag optimizes away some of them.
