What is VTI? Is it an assembler of some kind?

 you dont have to change $60001c if you change to something lower than 
240pixels,
 but you you will probably have problems with grayscale if you don't...
 another bad thing is that VTI does not support this feature, so all 
developement
 with different screen with has to be done oncalc.
