Reversed it time ago, i think GMO was S5.
If its not properly working u may need update a ITEM_BLOCK = $54 Lenght :wink:
here u can download item.bmd file ( the one i used when reversed this func ).
Finnaly atached source of a project to thread @Atachaments
PS. structure of Item record u can leach from Items.txt!
PSS. Delphi < 2009 users change TArray to Array of ...
can convect into C++ ?
I'm not familiar with C++ syntax. I could convert C++ to Delphi only :(
Added:
Anyway the code itself is very simply, i see no problem to convert it to C++
