SLK editor

Is there an SLK editor ot there? I mean not just for the units and spells there seems to be other stuff, like Units. I'd like to create custom soundbanks and stuff like that.
Also, is there a hacking guide for the game.dll? Maybe in a good few years time we may get the sourcode to it but it's doubtful.

1) Microsoft Excel, a component of Microsoft Office is the best spreadsheet editor out there. It can also edit SLKs.
You can also try any other spreadsheet editors. StarCalc, which comes with StarOffice can also edit SLKs.
2) There is no specific game.dll hacking guide I know. But good idea:D .

SLK Editor is included in W3M Map Utilities.
it's possible editing slk files without MS EXCEL.

Thank you!

Is there anyway to make new morph spells? I want to make one spell where my hero turns into a big giant monster. I guess I could use the Demon Hunters abilities, I'm replacing all the races in my mod, but I'm going to want other morphs too.
