Incrementing/Decrementing codes

[Emu]

This tutorial was by me..

Now we will use a money code for any game you wish.

this is what we (as in I) would do:

load the upper controller address into t0
then you would load the lower half of the controller into t0 and back to (t0)
we then load our button and 0 into t1 and set your button value to Increase
we then load our button and 0 into t2 and set your button value to Decrease
now we load our upper code address into t3 
we branch our controller t0 and our button t1 to the next branch address
nop is our line delay
now load the 2nd half of you code address into t4 and back to (t3)
we then load our button and 0 into t5 and set your increment rate
now we add t6 t4 and t5 - this says add t4 and t5 and store result into t6
now we store the 2nd half of our code into t6 and back to (t3)
we now branch our controller t0 and our button t2 to the end line which is jr ra
nop is our line delay
now load the 2nd half of you code address into t4 and back to (t3)
we then load our button and 0 into t5 and set your increment rate
now we subtract t6 t4 and t5 - this says add t4 and t5 and store result into t6
now we store the 2nd half of our code into t6 and back to (t3)
jr ra - ends our routine

Use thes commands:

lui
addiu
sw
add or addu
sub or subu
lw
bne
jr ra
j - for your hook

Don't forget the Negative rule and your hook.
