Extracting resources from Heroes 3.

If only you could specify exactly where to look.
Otherwise, there's no need to go digging around. Everything is readily available.
Find the file in the heroes folder: \_hd3_data\Common\cursors.dll
Use any executable editor (like ResourceHacker) to extract the necessary .cur files.

You can easily extract all other graphics and resources using MMArchive.

And in the game itself, the cursors are stored in H3sprite.lod within the animations.
