... here is an atari st emulator for Wii based on hatari...

 

Some notes

 

1. You will need USB keyboard to use this emulator
2. Mouse is emulated using Wiimote (A for click), you can also use USB Mouse
3. Press F12 to access the menu (probably i should assign one of the Wiimote key for this),
4. Options can be saved to disk
5. Press home, or alt-q to quit
6. Floppy images can be placed in \hatari\fd
7. EmuTOS image have been included. With EmuTOS ROM, the green screen flickers a lot. It doesn’t happen with some real Atari ROMs that I tested.
8. Sound works (usually), just enable it through the options
