Hey, I was just reading around the site what's different about each patcher that is posted (i.e Abyss does x while Tiara Moonshine does y and z) and I have a hard time trying to understand what Frontend is supposed to do in general. I'm not trying to ask where to download it, just what is it. o:
Patcher = memory edit
Tiara = data edit
Patchers change how the game functions, such as borderless fullscreen mode, altering the default ranged attack to auto-load magnum (or other) instead, embedding CP view into alt view, etc.
Data edits change how the game appears to function. Such as fonts, textures, etc. Mostly for lag reduction. But there are a few extra things you can do such as adding items to the list that dolls will pick up.
Recommended to have tiara + 1 patcher (such as abyss or kanan)
Frontend is... A frontend.
Frontend -
COMPUTING
(of a device or program) directly accessed by the user and allowing access to further devices, programs, or databases.
Short version: It manages all your mods for you. Also downloads them for you and updates your game, and can repair your install if you break it.
