True. But the current speed codes in this thread have the same issue.
I might, then, suggest a different speed code for use with Gateway or including in the NTR plugin:
Code:
[Run Speed Multiplier x1.375]
D3000000 00000000
0039AF74 3F800000
DD000000 00000002
0039AF74 3FB00000
D0000000 00000000
It's different from the currently available ones in this thread in that it's only active while pressing B, so it automatically engages while you are running and — as long as you don't keep pressing B during cutscenes — shouldn't mess with cutscenes.
It can also be disabled, while the current speed codes in this thread can't (or, rather, you need to enable the x1 code instead).
I haven't noticed any issue. If the text is all there before a required animation ends, the game simply waits until the animation is done before allowing you to dismiss that text message.
