What does an 07 code do?

It's the string code incremented to write to the 0x81xxxxxx area;

= CST3 : String Code =

06______ YYYYYYYY : Patch code (ba)
d1d2d3d4 d5d6d7d8...
writes d1d2d3d4 d5d6d7d8... at ba+address.
YYYYYYYY is the number of bytes to write

If I'm not mistaken, you'd use 0x91xxxxxx as the base address (ba);

(in example Mem2 16bit write (ba))
42000000 91000000
02531492 000003E7
E0000000 80008000

ba is aligned to be divisible by 0x2000000, so 91000000 won't work as expected.  It should instead be:

42000000 90000000
03531490 000003E7
E0000000 80008000

Of course, that is assuming that you want a 16-bit write.  For 32-bit it would be:

42000000 90000000
05531490 000003E7
E0000000 80008000

Alternatively, you could use po (this example does a 32-bit write):

4A000000 91531490
14000000 000003E7
E0000000 80008000

Or you could use po like this, it would work since po isn't realigned:

4A000000 91000000
14531490 000003E7
E0000000 80008000

Mind you I've been using an old version of WiiRD so the handler may have changed.

WiiRD doesn't load the code handler into memory, Gecko OS does.  Only the Gecko OS version will make a difference in regards to which codes do or don't work.

What if I want to add an IF code to the MEM2 code,
example:
The Code
42000000 90000000
03531490 000003E7
E0000000 80008000

I want to make it like IF 91531480 = FFFFFFFF then  write 03E7  to 91531490
how do it do that?

[TNTkryzt]

20______ YYYYYYYY : 32bits If equal (ba)
increment the 20 to 21 if reading 91 area;

The Code (ba)
42000000 90000000
21531480 FFFFFFFF
03531490 000003E7
E0000000 80008000

Yeah thanks adding 01000000 to the address solve the problem. Learned something new today  :)
