Which version of SH4 do you have? What folder do you have the game installed in? If you have v1.4 of the game, TMO 2.5 is not compatible. You shouldn't need the "Aspect Ratio 16 to 9" in the newer versions of the game at all. If you have an LCD monitor, it has a "native" resolution, which Windows will show as "recommended". That is what you want to set Windows to. Once in the game (without that "Aspect Ratio 16 to 9" mod activated) and at the main menu, choose Options, then Graphic Settings, and in the drop-down box for the game's resolution, you should find a setting that will match the Windows "recommended" setting. That's what you want. Apply, then Back and Back and exit the game. Re-start the game, and you should have a full-screen SH4 without having to do any add-in mods for, ala SH3...
