You will have to run the x360ce.exe program in each folder to produce the ini and dll files that are custom to each game. You can not just copy the ini and dll files from one folder to another. There are numerous game specific settings that x360ce knows about and it customizes when run from within the game's folder. Please read through their
Forum if you are having trouble with a specific game. X360ce does not work with every game. There are several tutorials on how to use x360ce listed at the top of the main forum page.
If the game needs the left and right triggers to operate
as analog values (like a driving game), make sure the quadstick is
running in x360ce mode, by loading a game file that has the x360ce mode
turned on in a Preferences sheet, like in
X360CE Configuration, prior to running x360ce.exe or the game itself.
Do not change the mapping between PS3 buttons and XBox buttons in the x360ce.exe program. Instead, if you want to have a different sip/puff/lip input activate a controller button, make a quadstick configuration file and remap the input there. Remapping in the x360ce program may pollute the x360ce database for other users.
