B ending for SS4 Goku?

Same thing happaned to me , at both gamespot and gamefaqs.com they say all you have to do is get the B ending by letting the enemy destroy 1-3 cities in the last chapter so i assume they mean the last level in the last chapter , and thats exactly what i did but nothing happened , i'd hate to ruin the excitment of getting SSJ4 Goku by downloading someone's saved game , so does anyone have an answer to this problem? i'd really like to play it through

I dont understand .. please explain in better context

for u to get SS4 Goku u have to beat all Z TRIALS in arcade mode

well i thought everyone knew this already but to unlock SS4 Goku u have to do every mission in the game it doesn't matter Wat rank u get on them u just have to do every mission that's how i got him ,and by the way his strength is z and move speed is z strongest character in the game.

i hope u like him from Ryan

im 8 years old and im in the last level but i can't beat it its too hard

Just pass the game once, I got Majin Vegeta and SSJ4 Goku after I beat Kid Buu with Gogeta.

i finished the game, and in the last level i got a C, and i defeated buu with gogeta and still i didn't get ssj4 Goku. can pls anyone help me?
