(This HLP is an excellent reference for learning OllyDbg. Unfortunately, the HLP format is not very convenient to use. When you follow the branch link inside and click for a few clicks, you don't know where to go. No way, this is the limitation of the HLP format itself.
In order to facilitate learning, I set out to convert HLP into the popular CHM format. Due to the limitations of HLP, and Microsoft's CHM tools are very outdated (1999), so the conversion process is not smooth, the Chinese characters decompiled by HLP are all garbled, and there are problems such as index loss...)
