Ah, the Atari forums, where it doesn't feel wrong to dig up really old threads...
Now that that's out of the way, I've been trying to get the CD version of Ishar 3 working on the Falcon, but this thread kind of meandered about and it seems the game is out there, I just bought the compilation of all three on GoG, but would rather play it on the Falcon, all I get when I launch it is a black screen, then if I hit the space bar it turns into a yellow/orange screen, then if I hit the space bar again, it gives me the TOS load up screen with START.PRG at the top. Unless of course I launch with the START040.PRG, which of course doesn't work anyhow, since I have an 030, but you'd think instead of the black then yellow/orange wouldn't even happen and it would just kick me back to the desktop.
Only thing I have loaded into memory would be hddriver.
