Alternate endings:
A new option will appear after completing the game for the first time. Use this option and load a saved game to restart with items obtained in the previous game. Complete this special game to view an alternate ending sequence.

To see dialogue from Chrono himself, choose the new game plus feature after completing the game for the first time. Defeat Lavos after Schala opens the seal on the door leading to the throne room. Before you go through the door, return and defeat Lavos to see Chrono scold Marle and Lucca for admiring men instead of showing a slide show.

There are about twenty different endings in the game.

To see an alternate ending which features Frog marrying Queen Leene, complete the game. After just saving the Queen go to Lavos by any way you can. If you defeat Lavos a sequence with Leene marrying Glenn, and Marle being a toad princess will appear.

Hint: Password to save Lara's legs:
When in Lucca's past, a note says that to stop the machine Lara gets trapped on, you must enter her name. Due to the button differences between the PlayStation controller and the SNES controller, spelling her name is not possible. The password is now L1, Circle, R1, Circle.

Hint: New Game+:
To get New Game+, you must complete the game by defeating Lavos through the Black Omen. After the game ends, reset to get the Game+ option to appear. When you choose "New Game+", you will be asked which save file you want to start with. Choose one of the three files and the game will start from the beginning. You will start the game at the same level, and with all of your spells and items that you had before. This option lets you play through to get each of the ten different endings. In a New Game+, a teleport (the Lavos Gate) directly to Lavos will appear in the right telepod of Lucca's invention at Leene Square. Depending upon when you enter this gate and defeat Lavos, you will get different endings

Glitch: Mistranslation:
After Crono dies and the Old Man tells you to go to 2300 A.D., go to Keeper's Dome. If you have not obtained the clone of Crono already, the Nu there will tell you to go to Norstein Bekkler, only, he will say "Nolstein Bekkler". The "L" and "R" mistranslation comes from the fact that, in Japan, these letters would be pronounced the same way. Many translation errors occur with these few letters.
