Hehehe!

I'm not really a game player, so my type of emulators run other operating systems like the Macintosh OS, DOS\Windows, Amiga, Linux, etc.

Arnim's site has most of those emulators, and a lot more, including some directions on installing them: http://pupnik.de/software.html

The other emulators that are not directly linked to can be installed via Maemo's Application Manager. I would just add all the repositories on the gronmayer site, then look through all the installable applications for the emulators like gngeo and xmame: http://gronmayer.com/it/index.php?lang=en&system=maemo4

If you have difficulting installing a particular emulator, you can ask for assistance here.
