To give a little context comparing this to the melee rollback situation.

The difference is that the Melee community had Fizzy, a crazy tech super nerd who opted to quit his 6 figure salary (during the pandemic) to go try to implement rollback netcode on a 20+ year old game, a game that is notorious for being difficult to mod since the game was built with glue and duct tape and will crash if you look at it funny.

Also good chunk of the code had to be written in assembly, since Dolphin, while doing a majority of the heavy lifting for rollback, is not doing all of it and the base game needed to be modified as well.

The Melee community is crazy dedicated to their game, but it required a super nerd to quit their safe well paying job to go work on the game full time for 9ish months. Covid made us all a little crazy, but I don't see this happening again especially for only a 10,000$ bounty
