Ostrich emulation help
 

hey ,
I have an old ostrich 1 that i am trying to use.. i would say its 95 percent set up... it connects,lets me download the bin to emulator, download file from emulator.. but when I "verify emulation RAM against the bin file" it fails.... what am i missing here? is it a certain buffer address i need?
its a $6E mask for a 165 ECM..
thanks
