Well for me personally I have mods installed on my copy of the game, which means starting up the game for the first time in a day is going to take a couple minutes anyway while it loads everything up, so I never even thought to try something like this. It might be possible but I think the most it would save is like 10 seconds at best. How often do you restart the game that the default loading of the game is bothering you? I'm just trying to picture the advantage. Do you have any mods installed on yours? You know it can't speed up the load time if you have mods installed right?
I can say from experience when the CPU has unlimited paybacks and those paybacks include auto reversal and resiliency, both instantly re-charging when receiving ANY damage, matches tend to go a lot longer and be considerably more challenging. Lots of changes in momentum and false finishes, big comebacks, back and forth action. I can probably figure out even more various tweaks to make matches more competitive in a fun way, yeah.
