How to write a wrapper method for a complex function?

[SaarHV]

Hello !
I recently came across the Box64 project and found it really interesting and impressive.

After spending some time learning about it (by gathering information from the website https://box86.org and reading the source code), I’ve developed a basic understanding of how it works.

Currently, I’m working on adapting some libraries to make them compatible with Box64. Simple functions are fairly easy to handle using wrapperhelper. However, when dealing with complex functions, I’m still uncertain about how to approach the wrapper logic. It seems closely tied to the original function's behavior. Could you provide guidance on writing wrappers for complex functions and share tips on effective debugging?

Thank you in advance for your help!
