Hi, there are two things I don't know how to do. The first one is how to use l+r before learning kamehameha (sometimes I manage to use the final attack vs bear or yamcha but don't understand how) that would be extremely helpful especially vs oolong which is annoying to fight and the other thing is, how do I do that trick on pilaf castle where I jump and then I use l+s? I find it very hard to do that, i don't know if you understand what I mean

Very late reply, but... the combo with L + R, you hold R and then when close to enemy, you press L. The wall jump trick is tricky but it's easier to hold R the entire time. Wall jump by pressing away then press L facing the wall and quickly wall jump again and repeat.

Oh god, never saw that one before too
