Help/Support Encoding Branch and Link BL sub_x

Zahir · February 26, 2015

Yeah, he pretty much explains what I already know. I just want to know how to encode BL.W sub_X to hex or if there's a program that can do it for me.

BL.W sub_44F08 -> CA F0 43 F5

Where the heck does CA F0 43 F5 come from?

ITS A BRACH ..

Okay, it's a branch. Now what?

Do what I said ..

Just follow his/her guide. I already understand how he got that hex value but too lazy to do it cause my PC is so slow it takes 30 minutes to do a string search in IDA

Wow, 30 minutes? I don't need string search, I can find the new functions in less than a minute. The problem is how to encode sub_B9D800 to hex. Otherwise, I would have whipped out my hack by now.

If you say you know it, please explain how to encode sub_B9D800. Because that's all I need.

This discussion is awkward. You can't encode sub headers as the real functions are not existing. Read tutorials how to hack branches it's really an ease.

@@Javi Tech @ you differ from the topic. Your way to get the HEX doesn't make any sense
