Well, I have two's ks 1.3... One of them came from AmigaForever (O yeah! I bought this time some time ago), and the other came from my A500, that was obtained using the winUae Tools (transrom).
I think... if this last is illegal... why WinUae team distribute this fine tool?
omen_ if you don't tell us (at last, me) nothing about your problem with your disk/image game, we (or I) can't assist you... :-D
