Should Dolphin Be Using Rollback for Netplay??

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

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 Smile

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