Title: What?
Hello everyone.

I'm trying to make some codes for SaGa 2 - English alternative patch.
My problem is the multiple offsets needed to reach the value.
I could sucessfully found all the pointers but my problem can you load an address found by an offset in a new offset?

It's like this
62176018 00000000 --> Verifying if it is the Pointer (Within battles seem to change sometimes)
B2176018 00000000 --> Getting this address to my offset.
Now the problem, the value in this offset, for example is [022CE13C] wich is pointing to a new location.
The location pointed (022CE13C) minus 8hex holds the following address [022CDF8C]
When I use this address (022CDF8C) plus 28hex I reach the location where the item durability of the 1st slot is.

Any ideas of how to put it? I just need to use a value in a offset to become the new offset.

Thanks Everyone

Here is how to solve your problem :

62176018 00000000 --> Verifying if it is the Pointer (Within battles seem to change sometimes)
B2176018 00000000 --> Getting this address to my offset (exemple : 0x022CE13C)
DC000000 FFFFFFF8 --> Substracts 8 (adds -8) from the offset (exemple : 0x022CE134)
B0000000 00000000 --> Loads pointer address into offset (exemple : 0x022CDF8C)
00000028 000000FF --> (exemple : writes 0xFF (8 bits) to durability of 1st slot item @0x022CDFB4)

However, I'm not sure that this post deserved a new topic in the Game Hacking Development forum.

Sorry if it wasn't to be posted but the info on ehacklopedia and other foruns didn't help.

When I looked ito this:
Type 0x0B Load offset BXXXXXXX 00000000
Loads the 32-bit value into the 'offset'. Offset = word at [0XXXXXXX + offset].

The [0XXXXXXX + offset] I thought it will be the value on a fixed Location and that the offset will be doubled.
Ex.: If I loaded the address 0x022CE13C into the offset using 0xB0, and use it again for 0x022CDF8C it would sum both addresses leaving me with value 0x0459C0C8.

I'm way used to programming and as when using manual increments I do: Variable = Variable + Increment; If Variable == 5 and Increment == 2, after running this line Variable would be 7. Might be my misunderstanding though.

Sorry again if it wasn't to be posted.

Aside: I've been trying to move this post, but it's not moveable due to something weird that happened during server relocation over the last few days.
