I'm trying to tweak a program that uses the SHGR screen to display a test
image on a GS (otherwise doesn't require a GS).
My old attempts to tweak the SHGR screen have been unreliable as I was
using some assumptions about bankswitching that may or may not be true to
access SHGR mode without switching to 65816 mode. I don't know anything
about 65816, honestly, though I have the ability to assemble 65816 code.
BTW, is it possible that the SHGR image on the existing crack of MECC
"Computer Inspector" is messed up? (This is the program in question.)
