while playing as goku or gohan use the kamehameha and then quickly press select then exit
and you will have invisible kamehameha's

you have to go to new namek and ask the nemekien then he will give it to u

First,you must unlock hercule, then go to the snowy highlands, and start beating up the
monsters.But first freeze them wityh the peace sign and when they start to glow white
freeze them again! I got to level 45 in 30 minuets!

let gohan have the kamehameha tecqnuicqe and while the energy realising press select
button and press b button and thats it your kamehameha tec nuicqe will be invisible

when u are ss and you are low on energy hold down a and when yourun out of energy you'll
go out of ss and after thats happend let go of a and you will be flashing until u hold
down a again or exit the area

if you are a different charecter than just run near the gators so they will follow you
once you gathered all of them stay in 1 spot to defeat them.

TALK TO ANY DOG CONSTANTLY AND IT WILL FINALLY SAY "WOULD YOU RUB MY TUMMY"

While playing as Trunks and Vegeta.Don't transform into super saiyan insted use vegeta's
energy punch and trunks sword blast.It will damage a lot.

go to gokus level 40 barrier and keep hitting the dinosour

FIRST IN NORTHERN MOUNTAINS,WHERE THE DINOS ARE LEVEL UP TO 40 ,THEN FLY UP TO TROPICAL
ISLANDS
THEN ON THE 3 RD ISLAND WHERE A GROUP OF ALLIGATORS RECIDE.TRY HITTING THEM   MANY A
TIMES

IF  U FIND ANYTHING NEW PLZ EMAIL ME

After you finish cellgames go to northern mountain and train with the dainasours and get
all your characters to level 40.after that go to east distrit 439 and go to the place
where youfirst batled general tao,green eggbots will be wating for you train really
hard,dont giveup and you would be level 50 in no time.trust me itworks.

get piccolo to lv 36 and it should be easy to beat him
(when the island breaks and u have to fight him the second time there is a little crack at
the top right corner  when you run out of ep just hide in the corner and wait till you
have enough ep then shoot ki balls  it might take a wile but it is easy to beat him

When fighting cell as Vegeta, try to stay SS. 
U can use close combat attacks but not so much. (Cell can steal your health with his tail)
If you need to use big bang attack, try to get as far away as possible to charge it up. 
Don't use the energy punch, cell just hits u before it lands.

When fighting cell as Trunks, find a safe spot and turn back to normal mode. (Trust me,
you won't last long asended SS long.
walk over to cell and hit him with a burning atk. It'll stun him so u can pound him with
punches and kicks, if he fights back, hit him again with the burning atk. 

Before Goku fights Cell bust the barrier walk to the spot before the cutsence, then go SS
and walk to the sence

go to northern mountains, and go to vegetas 50 level barrier. but kill all the monsters on
the way there. go back to the world map post (dont leave) killing all the monsters. then
repeat a couple of times to get easy experience (faster then killing the dinosuars) only
when your level 48-50
