You need to patch the exe with a hex editor to disable layout randomization. Change offset 0x186 from 0x22 to 0x23.
Here are native addresses for b944 (social club version): http://camx.me/gtav/...sses-b944_2.txt
Why post the addresses when the base is dynamic?
A bit late to responding to this, but I finally figured out what Cam meant. Basically, you want to turn on the "Relocation stripped" flag for the Characteristics of the PE. Steam version offset is 0x17E as of 944.
Thank you so much for this tip. I can finally create my own dumps!
