Here you can find Amiga-emulators.
But don't forget, first you need a Kickstart-image in order to get them to run.
You won't find any Kickstart-images on this side.
But with every emulator-download you get a description how to create one.

This is Win UAE V.0.84 R4. Needs at least Windows 95 and a fast computer for good results (P200+).
 

 This is the Dos port of UAE. It is faster than the Windows version.
 

The best emulator for Amiga games. It is very fast and compatible.
