well, the higher is better... i play at 1920x1080... so i know, but the person above, is asking for lower resolution, not higher '-'

Sorry but 1024x600 is not supported by Iris natively.
You can however do a hack to make your screen support 1024x768 by enabling scaling.
Search google for "display1_downscalingsupported" and you will find plenty of pages explaining how to do it.

It is, but playing at full resolution is always nicer :P

1024x768 not enough to play it? '-'

Yush , the truth has been spoken. I play iris with 1336x768 Fullscreen ... double boxing can be really annoying xD maybe if you go with maximum resolution you could play the game.

And well ... idk if that x600 causes glitches of some kind o-o
