But can you tell me what LDRB is and what it does? And btw. can you tell me, why do i need gdb or lldb to hack a game, when you can hack everything with ida and HxD?

I'll help ya. First of all GDB is broken for watchpoints but great for breakpoints. LLDB is best for watchpoints.

You use LLDB to hack sub_xx (X being a variable) and you need a Windows or Mac. I use Mac cause it's easy. There are Windows tuts too.

LDR and STR I'm confused on right now...

Add and Sub is simple (adding and subtracting same with SUBS AND ADDS).

Hxd is hex which you need.

---> mod the MOV or LDRB to BX LR (in hex converter = 70 47 for 2 byte and 4 byte I'm not sure). Most likely it should be the MOV. Otherwise it would be LDRB. I'm confused on LDR AND STR. MOV is sort of making sense but try it out. You never know when it will work or not. Need more help I'm right here

Use LLDB for iGameGuardian addresses to set watchpoints on addresses that change. For example, if you hacking coins in a sub_x game, then you search the coins on game guardian and keep decreasing or increasing the value of coins in game and then keep searching for the coins until you reach an address with 2-3 addresses. It's pretty confusing and It took forever for me to learn.

Believe it or not I'm only 14 and I started this when I was 13. So I'm still learning.

Or you could hack with strings on Ida but sometimes strings are useless so don't rely on them for everything. Any other questions.
