It is indeed the applications that are in cause. I tried zsnes which is not
usable in other resolution than the original 256x224, I also ran the amiga
emulator e-uae which does not support upscaling but only resolution changes.

Other emulators such as dgen for the Sega Genesis or gnuboy for the game boy
have a software scaling option working really well. One solution would be to
patch each problematic application to support 1200x900 but it's will not be
possible with closed source software.
I'd also like to try to run games that ran on 1999's PCs such as Quake 3 and
Unreal Tournament, I think the laptop is powerful enough to run these games
at a 400x300 resolution but i doubt it will be smooth at 1200x900.

I have found this message :

x.org mailing list and it might be what i'm talking about, I have to give it
a try.
