Converting the unnamed function sub_4016E0 into a real restored function name

[mrmaller1905]

Are there ways to convert the unnamed function sub_4016E0 into a real restored function name? I'm reverse engineering a game named London Racer: World Challenge using IDA.

 

Thanks in advance.

If there's no accompanying debug info I fear: no.

(Most games use dlls - you may find function names in there.)

Is there a way to restore the original C++ code?

Without the debug info mentioned you're usually faster when rewriting from scratch.

There's many tutorials online, here for IDA.

 

I'd suggest to compile a small 'Hello World' program with a counting loop for example - then try to get the say 5 source code lines again from the exe.

This will show the problem(s), imho.
