About
The availability and reliability of Gamecube controllers has been a long-standing issue in the Melee community. By now, it is fairly common knowledge that not all controllers are created equally - the disparity in quality of these controllers affects important movement techniques in Melee, most notoriously dashback and shield dropping. Controllers are becoming more expensive, and few players have the luxury of testing a multitude of controllers to find one that is reliable. This creates an arbitrary discrepancy where some players can perform techniques more reliably than others, for the sole reason that their controller is a better pick.
These controller issues are an artifact of Melee design choices that are not favorable for competitive play. This includes a one-frame dashback window and a shield drop window only three units thick - both so precise that minute differences in controller calibration make all the difference.
Universal Controller Fix (UCF) aims to fix these discrepancies, so that any controller is on par with a "good" controller - without going beyond what is possible in vanilla Melee.
This means with UCF, any given controller will be able to perform techniques as reliably as expected from a "good" controller. Those techniques will not become easier to perform than they already are on good controllers. They merely become as consistent as what good controllers already allow players to do.
UCF was developed in response to the community's desire to fix these issues, but their reluctance to put any of the existing proposed mods into practice due to unwillingness to change Melee's game design. We hope that UCF becomes the standardized controller fix solution that TOs find reliable to use in tournaments of any size.

Technical Info
UCF currently incorporates the following changes.
Dashback
The window for dashback has been increased from one frame to two frames. This is done by allowing the first frame of tilt turn to cancel into dashback. There is an extra conditional for Ice Climbers: If the second-frame dashback is activated, the correct controller state is retroactively applied to Nana, so that her behavior is as expected, without causing any new situations.
Giving one additional frame for the dashback window enables any controller to perform dashback consistently. The code has been tested such that the input required to do so feels the same as what an ideal controller is capable of in vanilla Melee.
Shield Drop
If the shield is angled such that shield roll is no longer possible, AND the control stick is being held against the rim, then spotdodge threshold is decreased from -0.7 to -0.8. In other words, holding the control stick to the side and rolling it downwards will lower the spotdodge threshold, preventing it from interfering with shield drop.
The design of this change is to mimic consistent shield drop methods currently possible on ideal controllers. In vanilla Melee, the popular Axe/Sung shield drop method enables players to reliably shield drop by angling the control stick from a sideways position down to the corner (or appropriate notch). The UCF shield drop change allows all controllers to do this without the need for notches or an ideal controller gate. Traditional shield dropping methods that are unreliable or slow in vanilla Melee (eg. angling the control stick straight down) are not changed whatsoever - only the Axe/Sung method is made to be consistent on all controllers.

Dolphin/Gecko Codes
These are the standalone codes for UCF that can be used in Dolphin or injected into other Melee mods.
NOTE: Dolphin has a limit to the number of codes that can be enabled at once. Since UCF is a large code, having too many other codes enabled may cause UCF or other codes not to work properly.

Memory Card Mods
These are .gci files that can be installed as a save file on a memory card, containing UCF and no other mods.
(If you're looking for a more complete mod package, UCF is also included in 20XXTE.)
