Hi, I tried UAE on my AMD64 machine and it segfaults rather quickly. There are some fairly obvious changes needed in gtkui.c which seems to assume that sizeof(void *) == sizeof(int) The attached patch fixes all such problems I have found so far, and UAE now runs for me. (so far) Regards, Martin. -- Binary/unsupported file stripped by Ecartis -- -- Type: APPLICATION/x-gzip -- File: 64cleanup.patch.gz
