[nbajamte] Power Up Cheats

[editing101]

Hi guys,

As some new discoveries have been made with the cheats for the original NBA Jam (thank you Pugsy ), I’d like to make a request to enable the ‘power up’ codes from NBA Jam TE on the MAME cheat menu.

As with the original Jam, you have to enter the following button combinations on the ‘match up’ screen in TE to enable the ‘power ups’ :

BIG HEAD: Hold Joystick Up and Hold Turbo and Steal
HUGE HEAD: Hit Shoot 5 Times, then Hold Joystick Up, hold Turbo and Pass
TOURNAMENT MODE: Hold Joystick Right and Hold All 3 buttons
SHOOTING PERCENTAGE: Spin Joystick Clockwise and Rapidly Tap All Three buttons
MAX POWER: Hold Joystick Down and Hold all 3 buttons Down and START
POWER-UP GOALTENDING: Hit Shoot 24 times (difficult!)
BABY-SIZED PLAYERS: Hold Joystick at DOWN/RIGHT Angle and Tap Turbo then Shoot then Pass 3 times.
QUICK HANDS: Hold Joystick down and hit Shoot 5 times and hold on 5th

The TANK GAME is not confirmed for TE - maybe a check can be done to see if it exists in the code?!?

As with the original Jam, the effects of these cheats are always confirmed on the game screen afterwards:


Big Head Mode


Huge Head Mode


Tournament Mode


Shooting Percentage


Max Power


Baby-Sized Players


Quick Hands

Pugsy/Abystus, is there any chance you can adapt your previous cheat format for the original NBA Jam to check the TE version for any power ups that can be enabled on the ‘match up’ screen? Any info you have would be great!

[Pugsy]

Found what I could replicate, no tank game as far as I can see.

I will need save states (MAME 0.187 or 0.188) for the other features as I couldn't replicate the keypresses...

Updated post save states.....

Huge Head is not ideal as the text is wrong but the head isn't. But it'll do...

Code: Select all

Thanks Pugsy ! Have the save states, and trying to attach to a PM, but can't see the option where to attach files?!?

Maybe try these variations on the cheats listed above to get them to work:

HUGE HEAD: Hold UP First, then hit Shoot 5 Times, continue holding Up and then hold Turbo and Pass
SHOOTING PERCENTAGE: Spin Joystick Clockwise (continuously) and Rapidly Tap All Three buttons (at the same time) at least seven times
MAX POWER: Hold Joystick Down and Hold all 3 buttons Down (without START)
BABY-SIZED PLAYERS: Hold Joystick at DOWN/RIGHT Angle and quickly press in this order - Turbo, Shoot, Pass, Turbo, Shoot, Pass, Turbo, Shoot, Pass.

Hope this helps

[Pugsy]

Can you 7z them all up in a single file (much smaller then zip) please, and upload to one of the free filesharing sites like https://mega.nz ?

[editing101]

No worries! Just sent you a PM with the info. Look forward to finding out more!

There's no PM in my inbox though?

Just post the link in this thread...if its a free host it doesn't matter if others grab them.

Thanks for the save states, updated the above post.

Huge Head isn't ideal but it uses a temporary RAM address which gets hosed...so I did it as ROM cheat which swaps any big heads to huge heads.

[editing101]

Great work Pugsy, cheers for that ! Huge Heads with Baby-Sized Players is certainly one of the more interesting Power Up combinations!

Sorry to bother, but is there any chance you can adapt these codes to work with either revisions 1 or 2 ([nbajamt1] or [nbajamt2]) of TE?

The reason I ask is that revisions 1 and 2 are the only versions of TE that contain the hidden MK characters (Reptile, Sub-Zero, Raiden, Scorpion), and it would be great to use these cheats with those characters

Hope I'm not being annoying by bumping, but I too would love to see this. Nice work with this and the Power Up cheats for regular NBA Jam as well. Learning Mode 1 also sounds interesting for either game, if it exists. Many thanks!
