Games at different screen resolutions?

[G.o.D]

is it possible, to create games at different screen resolutions?

Not just the camera size, but the whole thing, that it looks identically lets say on 1280x960 and 640x480?

i want to make a game for pc and gp2x, i know about the 640x480 gp2x thing, but 640x480 is way too less for a modern pc game.

if not: @developers, would it be possible to go one step higher, meaning to allow 1280x960 for 'gpx2' games, scaling it down to 640x480 on tv out and 320x240 display as it is now with 640x480?

yeah u can create game at diff resolution

[G.o.D]

what i meant is: if i now start a game, i have to make the graphics at a resolution that does not look too crappy on a modern pc, lets say i make a background graphic covering the whole screen at 1024x768, so if i then want to export this game for gp2x, which has a screen resolution of 320x240, i go to config -> game properties and set the screen resolution to 320x240, but what happens then, is that the graphic is still 1024x768, so just a small part is visible. what i want to, is making the game in a 1024x768 resolution, and later say: export everthing to gp2x at 320x240, scaling all graphics, positions and stuff to 320x240.
