To do this cheat you need to have beaten the game.

(This does NOT affect your game in a bad way)

Go to West city. Switch to Vegeta. Turn into a Super Saiyan. Swich to ANYBODY BUT Goku. Go into Capsule Corp. Go straight until you get to to glass doors. Read what the text box says and click yes. Wait until the tornement starts. Look at Vegeta and he is in SSJ transformation.

Happy Glitching

When you go to get the great saiyaman outfit in the beggining of the game right before you hand bulma the capsule go super saiyan and talk to her you will see that when you stop talking the floor on the bottom of you turns a weird colour

To always get the fusion right with Gotenks or Gogeta press up, b, left, down, a when it's your turn and you will always get the fusion right.

Press a,b,l,r,select,and start at the same time.

In kami's look out go into the room next to the hyperbolic time chamber go SSJ, SSJ3 and the fusions SSJ and stuff work to then go to the window your player will fly out and enjoy your highly pixelated SSJ flying about.
