Crystal Cavern Disc Eject (PS2)
probably illegal for runs but it exists, there are a few more disc eject oob stuff but they don't really do much. the game has load triggers and hard load lock zones, if you hit a load trigger then eject the disc the game just continues until you hit the load lock zone with your camera that freezes the game and says "loading" until the game loads, normally these zones are just as you can see where the map isn't loaded but by being oob we skip this zone and can inf hover right to the grade that is trapped mid air then get the game to continue loading by putting the disc back in
