+// When widescreen is on, the game intentionally crunches the vertical FOV slightly (by 1.12x), for some reason.
+// We can just undo this effect by setting the multiplier to 1.

+// Fix game hang on fade out after cellar in mission 6
+// The game initiates a fade out in a cutscene, then when the fade out is very nearly complete exits the level, which initiates a new fade (in InitFadeEx).
+// The game then takes the fade progress (incredibly close to 128.0f) and subtracts that from the goal value, 128.0f. This value is then
+// divided by the rate (0.25) and you end up with a pretty small value.
+// However, the game also then, for its fade update code, multiplies it by the deltatime before adding it to the progress float.
+// At 60fps this increment value becomes too insignificant to affect the fade progress value each frame, so the game effectively hangs.
+// We can fix this by clamping the minimum bound of this increment value so that it doesn't become insignificant.
+patch=0,EE,20151828,extended,080812F4 // j sceCdChgSys
+
+// sceCdChgSys has no references (and actually just prints an error that it's unimplemented), so we overwrite it for a code cave to do the bound check.
