Is it possible to overwrite old files and point to a new one?

[OneAndOnlySolo]

I am currently have an old version of a game (version1) and want to overwrite it with the new version of the game (version 2)? Is it possible to delete the old file/overwrite it and point to a new one? How would I go about doing this if this is possible.

Just right click and edit the game in LB In the launching tab change the rom path to the new one.
