Good morning, my italian friend, AMIGASYSTEM,
please read first what Steril707 is really trying to do, even it seems to be pretty pointless in my eyes. He want's to run AfA_OS on OS 3.1 and NOT on OS 3.9 BB4 or whatever. I must admit that I was surprised when I saw that AfA_OS really claims to support OS 3.1 in its guide. I won't expect support for any of the more sophisticated features of AfA_OS under OS 3.1.
But why not experimenting with illusions?
