Simon Kagstrom has released the latest verson of UAE Amiga, an Atarti emulator for Wii.

Instructions and developer notes:

"Installation

Untar the binary release on your SD card, Which Gives You a structure as follows:

uae /
uae / uaerc
uae / floppies /
uae / Roma /
uae / harddisks /
uae / saves /
apps / uae /
apps / uae / boot.dol
apps / uae / ...

Amiga kickstart image go Into uae / roms /, with the default name from uaerc Being kick.rom. Thereafter put your pictures in uae floppy / floppies / and you are set to go.
[Edit] Where do I get Amiga kickstart roms?

The Easiest way to get a set of Legally Amiga kickstart roms (and games) Is To buy the Amiga Forever CD from Cloanto. To use this with UAE-Wii, Perform the Following Steps on your host computer:

1. Copy everything from the "/ Amiga Files / Shared / adf" directory on your Amiga Forever CD to / uae / roms / on your SD card.

2. Copy / Files/Shared/rom/amiga-os-130.rom Amiga to / uae / roms / kick.rom on your SD card

3. If You Have upgraded from version older than 3 year, remove / uae / uaerc.saved from your SD card

You Can Also dump the kickstart-rom of one of Your Own real Amigas, this Requires a rom-dump program (Can Be found here) and You Will Need to Be Able to transfer files to and from your Amiga. The Easiest Way to Achieve This is a year to use Amiga aussi That Can write PC-DOS disks (Amiga Workbench 2.0 or higher) or by using a terminal program on Both ends and a null-modem cable. Lemon Amiga HAS more help on the subject here, They Also explain how to transfer games.
[Edit] Configuration

UAE IS very configurable, so take Some Time to lookup how the configuration file format works. There are Three configuration files, uaerc, and uaerc.saved uaerc.user. A lot of configuration options are configurable from the menu system, and Wii UAE Will save the current configuration as if uaerc.saved Something has-been changed. The contents of this file override the defaults in Will uaerc, and the contents of uaerc.user (optional) Will override Both Other configuration files.

The menu support allow Selecting Which model to emulate amiga. When switching model, UAE Wii Will try to load a matching kickstart image and thereafter reset the computer. If the kickstart IS not found, it Will keep the current, this goal Remember That Might Give You have not fonctionnement Amiga. The model / kickstart mapping IS AS FOLLOWS:

A1000: uae/roms/amiga-os-120.rom / uae/roms/kick12.rom
A500: uae/roms/amiga-os-130.rom / uae/roms/kick13.rom
A600: uae/roms/amiga-os-205.rom / uae/roms/kick205.rom
A1200: uae/roms/amiga-os-310.rom / uae/roms/kick31.rom
