Hy.
It only support:
640x480
800x600
1024x768
1280x960
1280x1024
You can change the resolution going to the C:/Users/(name)/AppData/Roaming/Electronic Arts folder (In Window 7 at least).
There open the "config.ini" and put your desired resolution in the "xres & yres" line. Like this:
IMPORTANT: After that, you have to right click in the config.ini and check the "read only" option. Otherwise, the resolution is not taken.
Cheers.
