Alrighty, I fixed some extra bugs and added one more small improvement:

• Added a person to the credits who got left out of them for the whole eight years.
  WE'RE REALLY SORRY! >.<
• Doubled the size of the sprite decompression atlas, which fixes sprite-flickering issues when you have, for example, two Big Band assists, Lenny, and a full Inferno Brigade onscreen at once. [spoiler]I couldn't have done this during the PS3 days, but those days are loooooong gone. :^)[/spoiler]
• Update - Fixed Peacock's SoID shadows that I broke.
• Update - Made the longer PS4-style super shadow trails the default on PC. If you don't want 'em, use launch option
  -disableextrasupershadows
  to go back to the old boring version. :^P
• Fixed the negative-damage training mode display bug after loading a savestate during a combo.
• The IPS display now gets saved along with your savestate in training mode, why not.
• Raised the thresholds for green/yellow/red ping times, as well as the updating the recommended-delay-for-ping numbers now that the netcode has been improved. :^)
• Update - the camera thing below was kinda annoying in practice, so I both improved it and made it opt-in. Use launch option
  -enablerollbackcamera
  to enable it.
  Improved the camera after rollbacks! Most likely you won't notice, but it does help some. Since this is a 2D fighting game, basically the only thing that we can nicely interpolate to hide jitter is the camera. This does not affect the position of the in-game walls, so it will not cause desyncs, it's only fixing where the screen draws. Here's a video with intentionally cruddy internet and a better explanation:

• It needs a new EXE to run, that should happen later today. Sorry!
• Note to our fellow devs:
  [spoiler]OpenGL Quads have been taken care of. Rejoice![/spoiler]
  

If this build has no further problems, it will become the Real Game in a couple of days.

I will look into what is required to update PS4 and Switch after that, but no promises.
