beat kid buu with goku ssj3 and you'll unlock him

can you type in a cheat to get majin vegeta

There's 2 ways the 1st way is 2 beat kid buu on chapter 7 and get a a,s,z.
The 2nd way is 2 beat chapter 7 but get 2 the bottom path If u get a b,c or less and then
go 2 chapter 2 and on the bottom path there will be 2 stages with Dabura faces and go 2
the last 1 and play it fail the mission and make sure it say clear condition failed then
go 2 the stage under it beat it and u can get ss4 Goku, but u must not beat kid buu so
this can happen. (worked4 me)
