Hey!! Okay, so I'm not really sure if anyone is still trying to deal with this issue, but I was today! For me, the issue wasn't at all having to deal with the secdrv, or any of that! Simply,
- Right click on the shortcut, and go to properties.
- In the Shortcut tab, enter xres=640 at the end of the Target command.
- Hit apply and run!
This worked for me. I ran it under this command, changed the screen resolution ingame, deleted the xres part of the shortcut, and not I am running flawlessly!
This was installed via an external disk drive, as my computer doesn't have one. I am running a GeForce 960M.
