Thank you! I changed the name of the HD of the partition on both sides, rebooted and it actually worked. I don't understand how, but I was able to move some games over and decompress them. I even managed to boot into the OS using AGAboost. Everything is moving PAINFULLY slow, but it works. I don't see how it can be possible to play a game on this setup, but it is fun to have MacOS 7.6.1 running inside the Workbench.
I have seen people playing Wolfenstein on a similar setup to mine, but I was just barely able to get Masters of Orion crawling along.
Hmm... Are you sure the "similar" setups were running AGA, and not a video card? That makes a HUGE difference to Mac emulation. Trying to make AGA run even a 16 color Mac is an exercise in trying to run your desktop through a slideshow.
