Editing Main.cfg
 

Does anyone here know if I were to change the resolution found in the file Main.cfg on line 28 from 1024x800 to something smaller, would that mess up my game at all?

Just a little system info, i'm running SH3 on a laptop with pentium M 1.73ghz, 1gb of ram, a intel 915 built-in graphics card. I know, I know, it shouldn't be able to run, but it does. Not very good, but it's playable.

It wouldn't make any difference at all. The resolution can't be changed by a config.

However, the is the XP SP2 Res Fix which is an external application and while I know it will increase the res, I have to admit that I've never tried to lower it.

Give it a go - HERE

Good luck.

P.S The resolution when playing in Windowed Mode is fixed and can't be changed at all.
