I want to change the activators from Wii-Mote+Nunchuck to Classic Controller Plus, where the activator is R+Left and R+Right
I know that button address for the CCPlus is 8057C66A and the activators are 0202 for R+Left and 8200 for R+Right
So where would I have to change/plug in my values to make this work?

why did you change whats in bold?? you shouldn't have. and make sure your button address is correct.
edit: i noticed your button address ends in a A and his in a 8 make sure your using a 32bit address aswell
Ack! Didn't see that. Let's try it again...
I'm using a 16bit Button address however.
This is the old way to do C2 codes before the code handler did all the branching for you. There is some significance to the address 8177C070, in that apparently it is never used. The ASM is then stored there. The 4A98B900 = b 0xFE98B900 is a hand-calculated back-branch to 4 bytes after the hook address. The last line, 04107994 496746DC, is the initial hook. So 80107994 is the hook address. 496746DC will make the branch at the hook address to 8177C070.

The ASM does a lwz, so yeah it should end in an 8 instead of an A.
Well now... I've changed it to this right now:

However it doesn't seem to register anything. I'll try a different button address then.
You could set an execute BP on 8177C070 while you're holding the button combination down, and then Step a few times to see what happens and to make sure it's loading from the button activator address you want
Hmm... no good.

you could try changing the code over to 16bit

Sadly that didn't work either.
I'm going to let dcx2 help you from here on out, i'm out of ideas besides debugging it myself, but i don't have the game.
My only suggestion would be to set an execute BP on 8177C070 and make sure that's getting executed. I would also watch the button activator in memory viewer with auto-update to make sure it's actually doing things. Press Step Into a few times and stop on the lwz r11,-14840(r11). Then press Show Mem. Press Run, then check auto-update, and make sure you're at your button activator address.
...hmm, I think I see what went wrong. Because the original code wasn't using lis/ori, the address must be handled different. The displacement operand of a memory access is signed! So instead of 8057C66A, you get 8056C66A. (it's subtracting! lwz r11,-14840(r11) ) This is the purpose of the @ha macro, to account for sign extension.
Notice how the original code uses 8058. Try this code instead.

You can also upgrade this to a proper C2 code and save a line.

Nice catch, I bet it will work this time around ;D
...wow. Something whacky-scary happened.
The C2 code wouldn't do it, but using the original version, I hit R+Left and time went backward (waaay too fast).
However pushing R+Right doesn't do anything.
err...what?
Did the C2 code not work?
The C2 one did not react at all (strangely) and the long version one can only make time go backward.
Is this what you guys are doing?
mr r27,r3 #I don't know why this is happening but anyways(maybe it's the address' instruction). Move volatile register r3 to non-volatile r27
lis r11,-32680 #is this the remote control?
lwz r11,-14840(r11) #load the remotes value?
cmpwi r11,8193 #compare remote with button??
bne- 0x0C #branch if not equal to
subi r28,r28,1 #subtract immdediate value by 1 if equal
b 0x10 #branch to ??? this is weird. could it be x14 instead?
cmpwi r11,8194 #compare remote value to this
bne- 0x08 #branch if not equal
addi r28,r28,1 #if equal add immediate value by 1
nop
if so I would like to do this
lis r12, 0x8057 #classic remote address
ori r12, ori 0xC66A (if not r12 then r11) #classic remote address
lwz r12,0(r12) #classic remote address value
cmpw r12,8200 #compare value with R+right
beq- ADD #branch to add
cpmw r12,202 #compare value with R+lef
beq- SUB #branch to sub
b END #if not branch to end
ADD:
addi r28,r28,1
b END
SUB:
subi r28,r28,1
b END
END:
nop # stop time (if the original value is placed here ie: lwz r28, 0(r27), the original value will then continue to count normally. Perhaps mr r27,r3 is necessary and could be placed here instead of the beginning.
I found a way around it, I'll just stick with brute-force poking addresses.
