Call POW Function Anytime [Vega]

May not work 100% on Wii Console. Works fine on Dolphin.

This code will allow you (at any time during the live race) to press your activator to initiate a POW. You can set what 'graphic mode' the POW Block will be during the time it is on the screen, and you can set the time it takes for the POW to spin you out if you decided to not dodge it.

Works online and offline, if used online, others will see you spinout as long as the S value is filled in correctly and you are in proper position to get spunout. If used in TT's, you will freeze.

S = Slot (tells the game which player slot threw the POW)
0 = Telling the game you threw the POW, slot numbers 1 thru B are for the CPUs.

M = Graphic Mode
1 = POW fully expanded
2 = POW slightly squished
3 = POW squished all the way

Any other values for M will make the POW graphic not appear at all.

The TTTT values is the time it takes for the POW to spin you out once the graphic appears.

Example TTTT values:
009F = Default
002F = Instant POW
FFFF, 0000 = No POW appears

XXXX is for the controller address and ZZZZ is your button activtor. When pressing the activator, do not press/hold any other buttons.

Final NOTE: This code makes use of memory addresses 0x81430000 thru 0x81430003. Make sure no other codes in your GCT/Cheat-Manager are using those addresses!

Hello Vega. I'm attempting to use this code for pow dodge practice. I'm practicing in VS race offline. I can activate pows all I want, but they don't affect me in first. It just functions like normal.
I am PAL. It's set to Nunchuk, d-pad down, M = 1, TTTT = default pow, S = 0

I use Riivolution with GXDraw Hook. VI Hook did not work either.
Gecko OS with default hook gives the same result.

This is the code i've used ingame:

7D606038 7C005800

B8610008 7D6803A6
38210080 4E800020
Try setting the S value to something other than 0.

Btw, I've only done testing of this code on Dolphin, so it may not be reliable on the Console. 1superchip created a newer version of this, but I don't think he has posted it on the site yet.
I set it to 1, now it works against myself in top 3 spots, it seems. Thanks! ^^
also had a funny moment where i got pushed while activating the pow, and the pow block got stuck in the air in the location where i got pushed, lmaoo.
