The load screen for TMO is a black/white photograph of one of the submarines with the late war conning tower, and the phrase TRIGGER MARU OVERHAULED across it. If you don't see this screen, it's not properly installed. My guess is you did what I did once. I manually created a folder in the MODS directory named for the mod, then unzipped the mod into this folder. If I did this with TMO, what I'd have is a structure that went like this:
Code:
MODS -> Trigger Maru Overhauled -> Trigger Maru Overhauled -> Data ->....
If you enable this, instead of moving the files to where they are supposed to go, JGSME creates a separate TMO folder in the main directory, so nothing works. Check the file structure on the mods.
