Dolphin, the GameCube and Wii emulator - Forums

http://skullgirls.com/2011/09/skullgirls-ggpo-and-you/ This explains why rollback is very important to emulating the offline experience, as someone that plays smash on netplay even the option to use such a feature would be very welcome.

I can't believe this didn't gain any traction.

Because you don't know how Dolphin's netplay works or why it desyncs in the first place

=o

Doing rollback with an emulator would require constant savestating (once per frame) and then, to do a rollback, reloading the save, re-emulating all the inputs, and trying to catch back up as quickly as possible. It would at the very least require an extremely fast computer and would probably introduce a lot of stutter because the "catching up" isn't instant like it would be in a non-emulated game.

This didn't get any reaction because it's been discussed to death before. Please wait in line behind the other people who have suggested it .

We attempted to implement this a while ago, it's not feasible for GameCube/Wii yet.
