It might be that this was supposed to be:

                if((!(VBFlags & CRT1_LCDA)) || ((LCDwidth <= 800) &&
(LCDwidth >= 600))) {

But why would people write a range from high to low?  That's crazy
people who write backwards code...
The numbers 800x600 (1024x768) indicate that LCDheight is meant to be used:
                 if((!(VBFlags & CRT1_LCDA)) || ((LCDwidth >= 800) &&
(LCDheight >= 600))) {

Hi

Nice, this is what is the point of fix this type of minor errors.
Sometimes you can find something more serious :)

New patch on the way!

Kind regards
