Do you do anything that a file name tells you to?


Anyway, I recommend SLADE3 if you want to open the pk3 to look through the files.
I didn't make the Sonia sprites and stuff, some girl made them in 2009. You can read up on who that was in the pk3, but the person fell off the face of the earth anyway.


You can dump the replays in the replay folder of your game and turn on the ghosts in Time Attack or what it's called to race them. Should take you a couple hours to beat unless you're a god or I forgot to spin dash somewhere.
