I tried changing the resolution manually before, and any changes I made refused to be saved. :( Actually, I was hoping there was some sort of cheat to use with the "-w" for windowed mode, that bumped the window to a larger size. The game window looks the same at 1280x720 as it did at 800x600, but the graphics inside it looks better, of course. I don't really think that changing the resolution any other way will make any difference to the size of the window. But thanks for helping me out, anyway.
