Yeah, Ive heard of this one too. First you need to beat the game to get new game+, but make sure you beat it in under 22 hours or the trick won't work. Ok, so start a new game and then get to the scene where you meet Kid. Press and hold triangle and R2 for ten seconds after she starts to talk to you, then press: start, L2, L3 (left joystick button), circle, x, x, circle, then finally select and hold it and then press start. Now put your controller on the ground facing the TV (it works better if it's parallel but it's ok if it's not) then leave it there for about six hours. When time is up stomp on it really hard (or maybe do a little dance, that's what I did). You should be transported to the End of Time. If Kid is with you reset because you messed up. Next go talk to Ozzie who asks you what the third song on Megadeath's second album was. Look it up on Google because I don't remember the answer. If you get it wrong the game freezes and you'll have to thaw it out and try again. But if you get it right you go into a fight with Lynx one-on-one. DON'T FIGHT HIM. Instead use the Chrono Cross and you'll be asked to put in disc 2. Do that and you should be at the start of disc 2 with Schala and Cyrus in your party! (Schala sucks though but it's cool to have her) A side effect of this trick is that all the enemies in the game turn into goombas but that's the price you pay.
