Second, backup your mvp2005.exe file under C:\Program Files\EA SPORTS\MVP Baseball 2005 and make a copy.
Third, load mvp2005.exe into the hex editor.

Find (ctrl + F) ' 20 03 00 00 58 02 '
Overwrite it with ' 80 07 00 00 B0 04 '
Now, there is one more ' 20 03 00 00 58 02 ', find it (ctrl + F) and
Overwrite it with ' 80 07 00 00 B0 04 ' Again.
Fifth, Save it (mvp2005.exe) and Run it!
When you go to the game menu, you will find '1920 x 1200' instead of '800 x 600'.
For 1680 x 1050, put ' 90 06 00 00 1A 04 '
