Request Make every move trigger a light shield before activating

I'm assuming you just want to be able to use the Impossible Cancel with A and B button presses instead of light shield.

Try pasting this into a text file in your Mods Library for Melee Code Manager. I can make it a gecko code if necessary:

MASTERCODE - Impossible Cancel v0.20
Allows other codes to implement the ICNCv020_softCancel function
Gecko codes can call this function from -0x3060(rtoc) (804DC980)

This will add 3 codes to MCM:
http://i.imgur.com/Hal2RWZ.png

- The first code is a Mastercode that includes the impossible cancel, but does not use it.

- The second code is the old impossible cancel code, using the master code.

- The third code is a new code I just wrote that also uses the master code.
It seems to work well enough -- adding the cancel effect to A and B button presses just before the player entities recognize the buttons.

Note to developers: You can call the impossible cancel effect from -0x3060(rtoc) as though it were a standalone function.

addi r3, rtoc, -0x3060
mtctr
mr r3, r30  # r3 = player entity start address
bctrl

This enables it for use in gecko codes. I've made this possible by including the static overwrites used for disabled Mytoc block 275.

ASM for the third code is included at the end of the mod in the form of a disabled code. Only lightly tested, so let me know if there are any problems (and perhaps expect them.)
