Attached is the start of the patch - if the screen is smaller than 640px wide, the scale factors are increased (though with a limit due to the maximum horizontal scaling being 2x because of the fast render routines previously discussed). I've tested this in the desktop; BASIC and games like Cannon Fodder (rectangular pixels, I think); Lemmings; Stib; Hopper; Chuckie Egg and a few others. > However, it looks like I didn't fix the mouse pointer image code to take > into account the scale factors, so you'll be wanting to change that. This version of the patch doesn't contain that code (given games tend not to use the hardware mouse pointer), however I'll look into it.
