Emulators?

[Garremp]

Seeing that over 200 people read this post i assume there is some interest in this topic.

I want the Pi to be an all-in-one Solution as HTPC (XBMC for Videos on my TV via HDMI, audio player on my stereo via MPD on the 3,5 mm jack), fileserver via samba on my external usb harddrive, as well as a simple gaming console (Gameboy, GBC, GBA, NES, Amiga). I "managed" to get the first few to run except the gaming part ("managed to get to run" is a bit much to say because most is already included in XBIAN and the rest is very simple to install).

The one feature i want to achieve is the gaming console and i really can not imagine that would take such a big part of CPU power (MPD runs below 1% in idle and up to 8-10% on full use. XBMC runs at 20-29% in idle and 60-70% playing a 720p movie. listening to music via MPD at the same time a movie runs is possible but absurd (even using using the stereo speakers within XBMC is possible).

So far i downloaded the package and compiled it (takes some time, a lot if you are getting many different emulators) but there i am stuck. if i run emulatorstation via SSH i get a display error.

I am an absolute Linux beginner and i can't even tell if XBIAN is running an X11 server, OpenELEC does not but there are many things you can not do on OpenELEC.
