OP also supports 1600x1200 res... in EZ-ini, if your monitor will support 1600x1200 you can set it there... or just open SFC.ini file with notepad and edit
lowres=6
the above list is wrong... lowres=5 is 1280x1024
using the in game screen red editor, or the utility that came with game, that limits you to a max of 1280x1024, but the game does support 1600x1200 and that is the setting I use on my 15" monitor on my laptop.. crystal clear view, especially with a 100hz refresh rate.
