Datel Wireless Retro Controller (Wii): Amazon.co.uk: PC & Video Games
Just got this for my Archos 101. It doesnt require a wii remote to work, it acts as a remote and classic controller in one.
I use wiimote Wiimote controller - Android app on AppBrain
to sync it to my Archos via Bluetooth.
It allows me to play lots of games on my Archos with a propper controller instead of the on screen buttons.
It works perfectly with Snesoid SNesoid (SNES Emulator) - Android app on AppBrain
and Gameboid emulators GameBoid (GBA Emulator) - Android app on AppBrain
Its awsome, because I can output to tv using the HDMI socket on the Archos and play all my favorite oldschool Snes games from the sofa.
