Normally you have to enter the following button combinations on the ‘match up’ screen to enable the ‘power ups’ :
BIG HEAD: Hold joystick up and hold Turbo and Steal
POWERUP DEFENSE: Tap Steal or Block eight times
POWERUP INTERCEPT: Tap Turbo twice, then hold down on the joystick and all three buttons
POWERUP OFFENSE: Tap Steal or Block 21 times (a very difficult cheat to get working normally - would be much easier under the mame cheat menu)
COMPUTER ASSISTANCE DISABLED: Tap turbo ten times (only works in three or four player games)
SHOOTING PERCENTAGE DISPLAY: spin joystick clockwise and
rapidly tap all three buttons at once until tip-off.
TANK GAME: Players 1 and 2 hold down all three buttons and hold down joystick at "Tonight's match up". (Already found by Abystus !)
The effects of these cheats are always confirmed on the game screen afterwards (see below):
Big Head Mode
Computer Assistance Off
Power Up Defense
Power Up Intercept
Shot Percentage Activated
To make finding these codes a bit easier, Abystus has already found the awesome tank game cheat in this thread:
By using the following address:
Code: Select all
<cheat desc="Play Hidden 3D Tank Game">
<comment>Enable before match-up screen is shown.</comment>
Since the tank game cheat is activated on the ‘match up’ screen, we can assume (?!) that the rest of the ‘match up’ cheats are at a similar address location on the rom?!
I have save states for five of the codes (Big Head, Defense, Intercept, Shoot %, CPU assist) if anyone needs them.
Thanks in advance !
