As helpful as it should be... there are parts that are frustrating.
If the installed version isn't the latest up to date version, you have to enter the info in this itty bitty tiny microscopic box before you force the program to recognize it's installed. When I figured that s*** now it thinks there are 2 versions installed. So I copy the directory, put it in a safe spot, then tell it to delete both versions. Well, I try. If gives me a box that I can barely the see the tops of some words and a Delete button. Spoiler: In spite of the warning, it didn't so s***. So I tell it to delete the entry. Again all I get is a box with Delete, and some words I can barely see the tops of. 'This action cannot be undone.' I'm just saying I don't have this program on my HD anymore, right? RIGHT!?
Aparrently not. Aparrently you're telling the Game Manager it does not exist on F95, and I never want to see it ever again, even when I update the game list. Well Thanks, it would have been nice If all of the writing wasn't misaligned so I could actually read what it said.
So, 1 permenantly borked game when all I tried to do was tell GL that I did not have the most recent version installed. Back to the old fashioned way for that game. Luckily it wasn't one of my favorites, and on the back burner.
I imagine once I get past the setup, and the learning curve, it'll be an amazing utility/tool. Some streamlining, better names for some buttons (localize makes me think you're searching for an English patch, not hey GL, the game is here!) 'Locate Game Folder' on the other hand... and fixing the warnings so that the words show up properly in the boxes.
