Things get very slightly further, but it now throws an exception -21 
(method not found):

Evaluating FCode...
call-method : exception -21

seek failed

Can't mount root

byte-load: exception caught!


Here's the debug output with your patch applied:

On first glance, it looks as if cstrlen is returning 0 which is probably 
stopping the method name from being set correctly.
