   Yes, I could, but I think Patrick used that routine for a very 
specific reason. I'll have to email him to be sure. If the use of the 
routine isn't neccessary then I could use ROM_CALL(DISP_GRAPH) or 
CR_GRBCopy and save myself around 100 bytes. But I do think the routine 
is essential to the game otherwise I'm sure Patrick would have used it. 
When I tried DISP_GRAPH before the game seemed to run fine, but when the 
ship gets hit an extremely wierd crash occured. I'll email PD and 
investigate further. 
    The real question for the CrASH people is why does this routine work 
in ASH and not CRASH? I could have told myself to write the routine out 
with ROM_CALL(DISP_GRAPH). Another question I have is why did the bug 
not used to occur when I played Orzunoid on CrASH v1.0? I have a feeling 
if someone tried Galaxian on CrASH v1.0 the bug wouldn't happen. 
    Sam
