I like to help people with Scummvm. I do it over on the official forum however the official forum turns away people who have clearly obtained the game without paying. Go check with a search for something like bin/cue.
I think this forum has the same attitude. Whatever, that's my approach.
Whilst you may have reasons for obtaining the game by download which are OK for example you purchased the game already but the disc is scratched so much it's unplayable again I'll take the official forums stance. In this case usually some sort of proof is needed like a photo of the game box and scratched disc.
Maybe others might help but it's like all things. Google is your friend.
