Tried it. Seems to work well. Good job on this, and thanks for making the effort.
Just a couple of caveats:
- The replays don't show what the FPS was when the replay was being made, making it possible for, say, a 40 FPS run to be passed off as legitimate. This isn't a deal breaker since it's fairly easy to tell when someone's cheating anyway, and there are ways to trick the in-game FPS counter in the canon games, but I still thought it was worth pointing out.
- The game seemed to lag a lot more than I remember. This one might just be me, since my computer is utter garbage these days, so I'd really appreciate other players testing this out for confirmation.
