hi, i make my own game called IMMORTAL.
Coz i dont have graphics for this game yet, i little improved my own engine
and ported game named Valhalla & Lord of Infinity to run on.

My prob is that i use improved files from this game. This first episode of whole Valhalla saga is free for
download for windoze platform on Vulcan Software WWWs.
Vulcan not responding on my emails.
What do you think about this ?
May i upload my gameengine with modified files or not ?

thanks.

Check the EULA for the game you modified the files. Or, just tell people where to download the original files and create a patch to turn them into your versions. That way, you are not distributing stuff thats copyright.

this game is what i talking about

first episode is free for download, when i install it under wine and check directory i cannot find any licence

If you can't find a license then I'd assume that the game can only be distributed non-modified, so your best bet to avoid C&D's would be to release a patch to convert the unmodified game into your modified one. Shouldn't be too difficult - all you need with most programs is a "original" dir and "modified" dir, and it does everything for you.

ok, making converting script.
