You mean buy anything in the shop?
I know a method but it takes a long, long, long time and I haven't tried it for a long time. Probably patched.
1. Take out MHS.
2. Attach to Engine.exe.
3. Click on something that you can buy then search 1.
4. Click on something you can't buy then search 0.
5. Repeat 3-4 until you get like 1 address.
6. Lock it onto one.
