I would install it for you if you weren't living in Germanistan
Seriously though, retroarch is great and can run pretty much every game in their original form, no need to wait for patches. The best part of that retroarch port is that it works in the background which means that you don't really see the difference between the retroarch games and the regular ones. They appear in the same menu with the same interface... and they just work. You can also install multiple cores (PCE, MD, etc...). You should definitely check it out.
