There are a few sites out there with the specs on AGI (The Sierra game
interpreter system) and even a few development environments. Sadly, the
development environments are all for PCs. However, if you generate AGI
game files for a version of AGI which you have an existing game for, you
can hack the  interpreter around a bit so that it's playable.
ie, if you have, say, King's Quest IV, which I think was the final version
of the AGI interpreter for IIgs, and you have some files which are at the
same AGI version (or at least close to it) you can switch out the files
from another game or ones that you have written yourself, so that you can
play it. I have done this so that I was able to play The Black Cauldron
and King's Quest IV on my mac, which never had mac counterparts, also to
play the older king's quests in color instead of B&W, etc. I don't see why
this wouldn't work on the IIgs as well, since the AGI data files are
universal, it is the interpreter which matters. However, I do not know how
well it would handle some of the GS-specific things, like extra sounds.
That might need to be specially written in as a contingency. (Like KQ 4
had tons of noises and sound that none of the other versions had, and
nothing out there had more than 4 voices at the time anyway compared to
the IIgs' 32...well, unless the Atari ST did, I guess. Or maybe the amiga?
Even the Mac SoundManager driver is scanty in it's support of sound in
early AGI games)
