Yes but what I meant was does it work if I have those.
Yes the game works if you have a gfx card and/or sound card.
Many people with gfx and sound cards play Total Chaos every day.
I do not have AGA output on my A1200.
Yes you do. Every A1200 EVER built by Commodore, ESCOM, Amiga Inc., or Joe Blow amd his brother Bob,
all have AGA output. Its a standard feature of all A1200 and A4000 Amigas built 1993-2003.
Look on the back of your A1200 for a connector that says RGB. That is it.
So unless you went psycho with a hacksaw, you've got AGA output.
It should run on OS4 without any modifications,
unless it accesses hardware past the OS APIs.
Wrong. OS4 API is different from OS3.x API.
OS4 API is not compatible with OS3.x API.
