SPEC256 is very easy to use.

First, download the emulator from the downloads page.

Once in you hard disk, unzip it to a folder. You'll see that the zip will create a folder for each game supported. Now choose a game in the download section. When the download finishes, then unzip it in its folder.

Execute SPEC256.EXE by doubleclicking it. Spectrum start screen will appear.

Press F7 to choose the 256-color game and enjoy.

Only currently supported games display 256 colours. The rest of the games will work as with any other Spectrum emulator (Load it with F5).

See the readme.txt for more details.
