Hi, so I found out that Apple is not using a 64 bit loader in BootX which I found from the Tiger install media. In order to keep it short I'll refer what I found in this message http://enhancedrisc.de/#20181015 . So now I'll look at producing 32 bit output to the cross-compiler and if it doesn't work, I'll probably build this from the macppc arch subtree. Regards, -peter
