08 Codetype Tutorial Wii

I want to write the value 42C80000 to each of these addresses, but the 04 codetype would take up too many lines. I want to shorten the amount of lines, so I can put more codes into my GCT. So, I'm going to use the 08 codetype to shorten it.

8115E620
8115E624
8115E628
8115E62C
8115E630
8115E634
8115E638
8115E63C
8115E640

Since, the addresses are > 81000000, we'll have to increase the codetype by 1. So, instead of using 08, we'll have to use 09 instead.

08______ XXXXXXXX
TNNNZZZZ VVVVVVVV

______ + ba = Initial Address
X = Initial value for the RAM write
T = Value Size (0 = byte, 1 = halfword, 2 = word)
N = Amount of additional addresses to write to (the first is assumed)
Z = Address Increment; in bytes (How many To skip By)
V = Value Increment (How much to add to the value after each additional RAM write)

To use po instead of ba, change the codetype from 08 to 18.
For values of ______ >= 0x01000000, add one to the codetype.

We change 08 to 09.

09______ XXXXXXXX
TNNNZZZZ VVVVVVVV

We take the first address and add it onto the line. Remove 81 because it will be replaced by the codetype.

0915E620 XXXXXXXX
TNNNZZZZ VVVVVVVV

We want to write 42C80000, which is 50 in Float. This number is displayed in Hex, but represents a Float integer. Replace XXXXXXXX with the Float value.

0915E620 42C80000
TNNNZZZZ VVVVVVVV

The value size of what we want to write to each address is a Word. Replace T with 2. XX = Byte XXXX = Half Word XXXXXXXX = Word

0915E620 42C80000
2NNNZZZZ VVVVVVVV

There are 8 addresses not including the first one as it is already assumed. Replace NNN with 008.

0915E620 42C80000
2008ZZZZ VVVVVVVV

The addresses only increase by 4, so replace ZZZZ with 0004.

0915E620 42C80000
20080004 VVVVVVVV

We don't want to write anything other than 42C80000 to each address, so we'll tell it to write nothing. Replace VVVVVVVV with 00000000.

0915E620 42C80000
20080004 00000000
