L2Server H5 decompilation process not total, only to facilitate the creation of extensions.

 

  • Define all C-Style / Unicode string in .rdata section: OK
  • Rename all functions according to the guard system: Next step 2641/10653
  • Create the entire structure of structures as specified in the .data section.
  • Create all VTables.
  • Create as many Enums as possible.
  • Set types to all functions.
  • Find the sizes of each structure and insert each one its size as _BYTE [xxxx];
  • Start manual decompilation in pseudocode.
  • Organize variables within each structure.
  • Finish manual decompilation of functions.

 

I defined almost all the C-Style / Unicode string variables in the .rdata section, I also made some preparations to later create all the structures.

 

This will not be achieved overnight, but little by little I will be adding updates.

Anyone who wants to collaborate will be welcome.

So H5 files are finally public? (exe files can be reconstructed from IDA DB)

Yes, finally! How I wish this had happened 8 years ago, but hey, for those of us who love this game, It's never too late...
