Re: A83: ti-83 slow???



When i ported Fast Tunnel from the 82 to the 83 i used the EXACT same sprite routines, disabled the interrupts for a time, and used almost the same code.  I even have a spiffy routine that copies the graph buffer through ports(not calls), which makes it run much faster than "_grbufcpy_V"

I think it is because of the coding of the sprite routines, which normaly use
the graph_mem and a slow ROM_CALL as opposed to the 82 ppl which access the
display controller directly.
