1.2.3

This is a hotfix to fix an issue with certain games that use Steam CEG, caused by me forgetting (CEG hasn't been relevant in many years) that CEG cares about the Steam install path. Not all CEG games perform the check that was failing, but ones that do would crash. Fixed.

Also included:

• Some work from @ElfariaKensington to improve game launch time. Slight differences, but you may notice them. Thank you, @ElfariaKensington.

• Adds German and French localizations thanks to @akeschmidi

More to come.
