# Stevedore (MSX, 2020)

Stevedore is an MSX videogame.

This game is to be played on an MSX computer. If you want to play it elsewhere you'll need to use an MSX emulator.

Physical cartridges are available at <a href="https://msxcartridgeshop.com/">MSX Cartridge Shop</a>.

The digital edition can be played online (and downloaded) for free at <a href="https://thenestruo.itch.io/stevedore">thenestruo.itch.io/stevedore</a>.

## Source code

Stevedore is written in Z80 assembly, and assembles to a 48KB ROM MSX videogame cartridge.

The full source code is available at <a href="https://github.com/thenestruo/msx-stevedore">github.com/thenestruo/msx-stevedore</a>.

This source code is provided for reference, archiving purposes, and educational uses.

### Stevedore and <a href="https://github.com/thenestruo/msx-msxlib">MSXlib</a>

The game is powered by MSXlib and, therefore, contains a snapshot of MSXlib.

Stevedore can be seen as the first full example of using (and extending) MSXlib.

But, if you want to use MSXlib yourself, please do not use the version in this repository. Instead, go to the <a href="https://github.com/thenestruo/msx-msxlib">MSXlib repository</a> to get a more complete, up-to-date, and better documented version.

### Toolchain

To assemble Stevedore, you will need:

* GNU make, as the build is `makefile`-based. You can bypass this requirement by manually translating the contents of the makefile into a `.bat` or `.sh` script.
* [tniASM v0.45](http://tniasm.tni.nl/) as Z80 assembler. Using a different assembler may require adjustments in paths and syntax of the source code.
* [PCXTOOLS v3.0](https://github.com/theNestruo/pcxtools) to convert the PNG images to TMS9918-ready binaries, and Tiled maps to binary files.
* [ZX0](https://github.com/einar-saukas/ZX0) v2.1 to compress the binaries.

Additionally, you can also use:

* [Tiled](http://www.mapeditor.org/) to inspect and edit stage files.
* [Vortex Tracker II](http://bulba.untergrund.net/vortex_e.htm) to inspect and edit music assets. You can use an alternative version such as [Vortex Tracker Improved](https://github.com/oisee/vti).
* [AYFX Editor](https://shiru.untergrund.net/software.shtml) to inspect and edit sound effects. You can use an alternative version such as [AY Sound FX Editor (Improved)](https://github.com/Threetwosevensixseven/ayfxedit-improved).

### How to assemble

Run `make`, as the build is `makefile`-based.

### Files and folder structure

The source code is comprised of:

* `makefile`: the build script.

* `games/stevedore/`: contains the main Stevedore source code, as well as the graphic assets, maps, musics and sound effects.

Note: intermediate resources (such as already-converted graphic assets, and already-compressed binary files) are provided for convenience.

* `lib/`, `libext/`, and `splash/`: contain a snapshot of MSXlib, the external libraries of MSXlib, and the main MSXlib splashscreen. Please do not use these version and go instead to the main <a href="https://github.com/thenestruo/msx-msxlib">MSXlib repository</a>.

The external libraries used in Stevedore are:
	* [ayFX Replayer v1.31](http://www.z80st.es/downloads/code/) by SapphiRe
	* [PT3 Replayer](http://www.z80st.es/downloads/code/) by Dioniso, MSX-KUN (ROM version), SapphiRe (asMSX version)
	* [ZX0](https://github.com/einar-saukas/ZX0) v2.1 by Einar Saukas

Additionally:

* `dist/`: contains the distributable package published at <a href="https://thenestruo.itch.io/stevedore">thenestruo.itch.io/stevedore</a>.
