Help/Support Modding using ida

[Cassidy Love 0]

I have

Ida

Hex editor

Online arm to hex converter. 

 

The game I'm trying to mod has jumbled up function names so only way to do it is via strings. 

 

I found the function where I need to do changes using xref, but issue is the xref also lists DCQ for same string. Does this affect the modding in any way? 

 

I'm actually trying to learn from a mod I picked up for same game just different version, it works mine doesn't, only difference I can see is dcq

 

also, how to find out which W or R register holds what value

like if i want to put a huge number in register w0, how do i know if i should use w23 or w29 etc? 

 

from what i understand registers are just variables and u can put any value u like in them, right?

they dont hold an intrinsic value do they

You can get details on it : 

 This is a good post to learn it. (I am also learning though and using this post for common details on it.)

r7 holds a value of about 803 million, but yea w23 should be a large value

for R registers i usually do MOV R0,#65535 or u can even do MOV R0,#5000 and MUL R0,R0,R0
