Adding to a value then setting it back to default?

[Lunar]

Ok so im trying to edit one of ukuneko's codes so Link grows, shrinks and sets his height back to the default. Im not 100% sure on how to do this (infact im not even 10% sure :S). I know how to set the value back to the default, but i have no idea on how to increase the value on that address.

Here's the code V V V, and i wanna add/subtract the values

Link Size Modifier [ukuneko]
48000000 804862BC
DE000000 80008180
12000018 0000XXXX \\ Here
1200001C 0000XXXX \\ Here
12000020 0000XXXX \\ And Here
E0000000 80008000

Help would be greatly appreciated.

Thanks

Increasing and decreasing is possible via Gecko Registers:

What you can do:

48000000 804862BC  //Load ptr
DE000000 80008180  //Check ptr
92210000 00000018 //load po+18 into gR 0
28XXXXXX 0000____ //grow button activator
86B10000 3F828F5C //gr0 = gr0 * 1.02
28XXXXXY 0000____ //shrink button (XXXXXY = XXXXXX+1)
86B10000 3F7AFAFB // gr0 = gr0 * 0.9803.... = gr0 / 1.02
28XXXXXY 0000____ //normal size button
80000000 3F800000 //gr0 = 3F800000 = 1.0
E2000001 00000000 //endif
94210020 00000018 //store gr0 to po+18, po+1C, po+20
E2000000 80008000 //terminator

96B10000 3F828F5C //gr0 = gr0 * 1.02
96B10000 3F7AFAFB // gr0 = gr0 * 0.9803.... = gr0 / 1.02

Shouldn't these be 86B1 instead of 96B1?

very probable, I didn't test the code..
