Do you already understand the principle of 640x480 mod with CC?
It's easy to explain.

1.Change the setting of monitor sense line to VGA/SVGA.
(short 20&24, open25 on logic board side)
2.Change 640x480(VGA) to 800x600(SVGA)
3.Adjust geometry

That's all.
But I say again.
There may be the "skew" on menu bar after mod.

option

"Some(not all)" LC575 can't display the screen correctly after #1 before #2.
If you can't see the screen correctly, it is hard for you to cange the resolution.
The case where it is not displayed is taken into consideration, and the following two files are prepared.
(You can download them from that site.)

Boefore starting mod, you need do these steps.
Change.hqx (You should extract it on a hard disk.:This is a "shareware".)
SVGA-AUTO.hqx (You should extract "SVGA/VRAM-1024K" and put it in "Startup" folder.)
Changing the resolution will be done automatically, when you boot first after mod.
