At CEOtaku, a number of people approached me and asked if I would add an option to the PC version to increase the input lag by 1 frame so they could practice for PS4 tournaments on PC.
Well, I done did it.
If you use the launch option
[spoiler](which, you may remember, existed before)[/spoiler]
it will now add the option
EXTRA Frame Delay (0 to 10)
to the Settings menu in-game, below GGPO Frame Delay.
This will let you choose from 0 to 10 extra frames of input lag at all times, and you can even change it from the pause menu. (That's 3-13 frames of total input lag, because the base amount is 3f.)
Online GGPO delay will be modified by this setting as well - if you choose 1f of EXTRA delay and 1f of GGPO delay, the actual GGPO delay will be set to zero so you still experience 1f of total lag. If you choose less GGPO delay than your local lag, GGPO delay will be set to zero.
Making it work the other way around was impossible, sadly...
