Repository Setup

You can add the repositories to your box in several ways, but they are usually bound to the Ubuntu flavour you are using (i.e. Ubuntu, Kubuntu, Xubuntu or other derivatives).

If you already know what to do, jump to the resource summary below. Otherwise, open a terminal window (commands may be typed directly or pasted into it) and:

Make sure wget is installed:
```
sudo apt-get install wget
```

Add the repository key to the GPG keys trusted by your box:

wget http://sdlmame4ubuntu.org/repoc/957AC3A6.gpg -O- | \
sudo apt-key add -

Add the repository for major releases:

sudo wget http://sdlmame4ubuntu.org/repoc/karmic.major.list -O \
/etc/apt/sources.list.d/sdlmame4ubuntu.major.list

Skip this step to stick with major releases!
If you want to upgrade to intermediate "u" releases, add the appropriate repository too:
```
sudo wget http://sdlmame4ubuntu.org/repoc/karmic.urel.list -O \
/etc/apt/sources.list.d/sdlmame4ubuntu.urel.list
```
Now update the information on your box:
```
sudo apt-get update
```
Finally install the package from the repository:
```
sudo apt-get install sdlmame
```

Well done! From now on, the update manager will take care of upgrading the package for you! :-)
