# Airport
# Overview
`Airport` is a free (as in freedom) video game for the original Sony
Playstation aka PSX. The player puts himself/herself in the role of an Air
Traffic Controller (ATC) where inbound and outbound flights must be brought to
their destinations safely and within time.
## Overview
While aiming for an arcade experience, `Airport` is inspired by real-world
procedures used in aviation so those used to realistic flight simulators might
enjoy this video game as well. While many features are still missing, the game
is in a rather playable state.
### What is Airport?
`Airport` is written in C using the `mipsel-unknown-elf` GNU toolchain and a
free SDK called PSXSDK, created by nextvolume. Since the original author stopped
developing it, a [custom version of the SDK](https://github.com/XaviDCR92/psxsdk),
bringing in new features and bugfixes, is used for this project. A map editor
is also available for operating systems supporting `Qt`.
Airport is an open-source video game for the original Sony Playstation aka PSX/PS1. The player puts himself/herself in the role of an Air Traffic Controller (ATC), where lots of inbound/outbund flights need to be controlled without delays.
The game has been successfully tested under real hardware (`SCPH-5502` and
`SCPH-102`), `pcsxr`, `pSX` and `FPSe` without major issues. It is also
compatible with [OpenSend](https://github.com/XaviDCR92/OpenSend), making it
possible to stream game data from a computer over the serial port on the
console, allowing quicker development under real hardware.
### What is Airport written with?
# How to build
`Airport` has moved from a `Makefile`-based build system towards `cmake` for
convenience, easier deployment and generation of `compile_commands.json`,
useful for improved text completion on some IDEs. `cmake >= 3.13` is required.
Before building, environment variable `PSXSDK_PATH` must be set to the path
where `psxsdk` has been installed (e.g.: `/usr/local/psxsdk`).
Airport is written using an open-source SDK called PSXSDK together with the GNU toolchain. PSXSDK can be freely [here](http://unhaut.x10host.com/psxsdk/ "PSXSDK official link"). However, a fork was created specifically from the 20150729 version with new experimental features and posted into [Github](https://github.com/XaviDCR92/psxsdk-20150729 "PSXSDK-20150729 fork").
`Airport` can then be built using the typical process in CMake projects:
```sh
mkdir build && cd build/
cmake .. -DCMAKE_EXPORT_COMPILE_COMMANDS=1
cmake --build .
```
Once built, two files namely `airport.bin` and `airport.cue` inside the build
directory (e.g.: `build`) can be used to play the game on an emulator or burn
it into a CD-R to play it into a modchipped console.
On the other hand, the map editor must be built using the Qt framework. Qt
Creator automates the process and thus is the recommended way to go.
