OpenArena appeared as a project in 2005. It is a free and open source first person shooter game made by the community. It looks similar and have identical game play as Quake III Arena. I even remember that a decade ago I used to play it at after work with my colleagues in the office on GNU/Linux distributions. This tutorial will explain how to get it working on PocketC.H.I.P.
Beware that the performance of this version the game on PocketC.H.I.P. is not good and you might be disappointed.
I guess that the performance of OpenArena on PocketC.H.I.P. could be improved with the proper EGL drivers and by recompiling the game from scratch. I have seen videos of it and another version of Quake 3 working far better on Orange Pi and Odroid boards. Both Orange Pi and C.H.I.P have Allwinner SoC.
PocketC.H.I.P. comes with mainline Linux kernel and there is a driver issue with the hardware acceleration of Mali GPU. In this particular case, probably OpenArena and Quake 3 will work better on image with Linux-sunxi version 3.4 of the kernel and its Mali drivers.
Follow the steps below to install OpenArena on PocketC.H.I.P. and to configure it to the bare minimum by disabling graphics and sounds effects:
Ensure that PocketC.H.I.P. is connected to a WiFi and open a terminal
