Actually, the scalers do *not* affect the GUI, so that point is  
moot :-). If we run in 320x200 with ASR and 2x scaler, then the GUI is  
drawn at 640x480. But if you run at 320x200 without ASR and with 1x  
scaler, it is, well, 320x200. And if you do it like me and run with  
ASR and 1x, you get 320x240, which is 20% more vertical space, and  
thus makes for a lot more space in both launcher and browser.

The PS2 should be able to run the GUI in 640x480 (rendered at that  
res), actually. If it doesn't, I'd like to know why -- if it is speed,  
then we *definitely* need to look into making the GUI code fast enough.
