The site is all about a browser-based emulator of the IIgs, but when a game is selected to run, the website includes a download link.

Installing the GSOS operating system and figuring out disk images are particularly tricky tasks.

This guide provides some bootable GS OS installation disks, a pre-prepared disk image and a few pointers for IIgs novices.

I hope it helps. If you need some more assistance, I can be reached by e-mail, or on my forum.

The homepage was lost when Geocities shut down, but a mirror is available here.

For what it is worth, I was using gsrom03 when I created the disk image (below) containing an installation of GS OS.

To select the ROM, run the emulator and hit f4 to enter the configuration screen.

After you have selected your ROM image, go the main config screen and select disk configuration and mount the disk image in the s7d1 slot (see figure one, below).

This is the easiest way to get started with the emulator, but it is not entirely recommended GS OS components are installed individually (from the system disks) by the user and my disk image does not contain every component.

If an application says that it requires a certain tool, you will need to copy that tool from the system disks.

Look for AppleIIGSSystem6.0.1 disks one through seven (probably near the top of the list).

However, the only way those files can be turned into a form that is usable by Kegs is from within a real Macintosh.

But dont worry, Ive done that for you myself: download a package containing all seven installation disks (in a usable form) right here.

Jorpho points out that using The Unarchiver for Windows, one can easily extract the install disks in Windows.

Read the whole topic for instructions that reflect the most recent versions of The Unarchiver (the initial instructions given are a bit old).

When the OS asks you what application you want to use, just hit cancel.

Now mount the (formerly) blank disk that you just installed to as sd71 (as youve noticed already, this is where all disks that you are going to boot from are mounted).

You should have a very basic install of the GS OS looking at you (see figure two, below).

Click customize and browse through the options available to you.

Create blank disk images (if needed) using CiderPress 3.0.0.

Just create through FileNewDisk Image.

The disk images should be formatted as ProDOS (the default setting of CiderPress).

A good source of IIgs games in disk image format (ie: mountable in the emulator) is Virtual Apple.
