Prerequisites
=============
- A homebrew enabled PlayStation 3 console. As of now that mostly means having a custom firmware installed. Obtaining and installing such a software is out of the scope of this document. Sorry, but you're on your own for that one.
- At least one ScummVM supported game. The list of compatible games can be seen here: https://www.scummvm.org/compatibility/
The page https://wiki.scummvm.org/index.php/Where_to_get_the_games references some places where those games can be bought. Demonstration versions for most of the supported games are downloadable on https://scummvm.org/demos/
- An USB drive.

Installing
==========
From a computer, download the installable package of the PS3 port from ScummVM's main site. It should be a .pkg file. Copy it to an USB drive.
After having plugged the USB drive to you PS3, the installation package should appear in the XMB under the "Games > Install Package" menu. Installing it copies ScummVM and its dependencies to your PS3's hard drive. It also adds the "Games > PlayStation 3 > ScummVM" XMB entry which is to be used to launch ScummVM.

Configuring and playing games
=============================
The user manual describes how to add games to ScummVM and launch them : https://wiki.scummvm.org/index.php/User_Manual

PlayStation 3 Specifics
=======================
Games can be launched either from an USB drive or from the internal hard drive. The internal hard drive has better performance though.
Savegames are wrote in the /hdd0/game/SCUM12000/saves folder.

Joypad button mapping
=====================
- Left stick      => Mouse

Building from source
====================
This port of ScummVM to the PS3 is based on SDL2. It uses the open source SDK PSL1GHT.

The dependencies needed to build it are :

- The toolchain from https://github.com/ps3dev/ps3toolchain
- SDL from https://bitbucket.org/bgK/sdl_psl1ght
- ScummVM from https://github.com/scummvm/scummvm

Once all the dependencies are correctly setup, an installable package can be obtained from source by issuing the following command :

./configure --host=ps3 && make ps3pkg
