contain ROM3.1 and OS3.x files required by AmiKit. Such a content is in Plus or Premium edition only:http://amikit.amiga.sk/amigaforever.htm
With Amiga Forever Plus or Premium you don't even need to download AmiKit from here. AmiKit can be simply installed and run via Amiga Forever Player directly (switch to Application tab, select AmiKit entry and press the download button. Once the package is downloaded, it gets installed automatically. Now simply doubleclick the AmiKit entry and enjoy!
