Activate Bullet Bill at Anytime [Vega]

This code will allow you to press your desired button(s) on your controller to activate the Bullet Bill whenever you want. There is offline version and online version of the code. The online version is untested, can somebody test please? =p.
  • Q (PAL only) 5 for GCN; 4 for Non-GCN
  • S (Offline version of code only) = Slot (0 for yourself)
  • XXXX = Controller Address
  • ZZZZ = Button to Activate (use Wavebird ZZZZ values if using GCN!!)

Link to thread of XXXX and ZZZZ values - https://mkwii.com/showthread.php?tid=44

FINAL NOTE: Regarding the offline version, if you want everybody to all be in a Bill at once, replace "2C1B000S" with "48000008", this gets rid of the Player Slot check.

Regarding offline NTSC-J and NTSC-K versions: aren't the "lis" instructions regarding controller adresses wrong? (3D808033 on NTSC-J and 3D808035 on NTSC-K just stands there)


I will try the codes today I think.

Oops. Thank you! Silly error on my part.

There's actually an instruction the lookup table I forgot to port. Got that fixed, I can test later today.

EDIT: Tested and all ports working. Apologies for not catching that when i was writing up the source for this code initially.
