Best Beyblade
Use Dragon Breaker Gamma Attack Ring, Star Attack Gamma Weight Disk, NEO Right Spin Gear Gamma Spin Mgear, Custom Grip Gamma Base, any Ultimate Launcher, and any Bit Beast.
Dragoon V2 Booster Pack
Win the Tournament once, then talk to DJ in the lobby. Win the Tournament again and go back to DJ to get the Dragoon V2 Booster Pack.
Easy wins
Do not always go for a crash out, as you will end up spending more money fixing your Beyblade than you will earn (or barely come out ahead from the cash standpoint). The best way to defeat your opponent is to force them next to an opening by coming up behind them, or in front of them if you are in opposite spins, then launching your Bit Beast attack.
Extra opening sequence
When the game first loads, allow it to idel at the "New Game/Continue" screen. If you wait for about two and a half minutes, a revamped version of the V-Force opening will appear.
Get Dual Dragoon bit beast
Beat the national championship once and talk to DJ in the lobby, and he'll give you the Dual Dragoon bit chip.
