Hi there!
If you want to play Fifa2000 in Widescreen just do as follows:
1.Downoald&Install GALAHs 3dPatch 3D Patch http://fifa.galahs.com.au/
2.Edit 3dsetup.ini found in Fifa2000/3DSetup/! You should find all resolutions lined up at the beginning of the .ini file. Just insert your desired Resolution into the row!
3.Now run 3dsetup.exe and u should be abled to choose the resolution u enterd!
Thise might work with older Fifa titles as well since GALAH released 3d Patches for those too. This 3dsetup.exe programm was widely used by EA at the time (98-~2001). So try it out on some older titels, maybe it works on them too!?
Ps.: Its stretched!
