The CRT hits the LC softswitches (and you can't prevent it from doing
so) so a cc65 program is probably not exactly the best platform for LC
diagnostics.

As long as you don't actually place code in the LC segment the CRT
doesn't rely on a LC being present. The softswitches hit are supposed
to do just nothing.

But if there's however a broken LC present which in example can be
turned on but not be turend off this will cause cc65 programs to fail.

Regards,
Oliver
