Yes, thanks a lot for your help (and Thomas too). I will wait for Darius to see if he can make it, but it has been 10 years since he used emulation ...
But don't worry, this afternoon I've copied or converted all of the icons so them all will be shown in AmiStart (v65) in my distro when using AfAOS
It's true that I've got also another set of icons, "Mattahan's icons set", but I won't be converting all of them, so it would be a pity if AmiStart can't fix the problems with AfA and the 3.5 icons.
