How do I change it? I recall something about editing a program shortcut. Also, would this work with large mode?
ZQuest's windowed resolution
In ZQuest, you can change the size manually in ag.cfg. However, this is not the same as the resolution. I think you can choose from 2 pre-sets denoted by a "0" or a "1" in ag.cfg.
I think the ZC Launcher lets you set the "resolution" for windowed mode. I'm not so sure about large mode though. I think it is what it is.
However, you can try changing the "scale = 1,0" or "fullscreen = 0,1" in ag.cfg. I dunno for sure though, ZQuest does not seem to have directly changeable resolution parameters.
Small mode - scale = 1(320x240), 2(640x480), 3(800x600). ..I think that's right.
Large mode...I don't think you can scale this.
Also fullscreen = 0(dependant on other settings), 1(fullscreen), 2(windowed).
