Add RetroPie SCUMMVM support

[DieKatzchen]

Retropie, similarly to Recalbox, requires an empty file. However, the extension is *.svm, it is in the root SCUMMVM folder, and the system automatically generates it with the correct filename (which surely makes things easier).

[DieKatzchen]

So I just saw that I can add the *.svm extension to the scanned files, but I didn't know that you're supposed to have the long name of the game inside the file for it to hash. Once I figured that out it worked fine, but there should be a note somewhere.

Sorry long time I haven't worked on the scummvm part... And there is a note...somewhere...on recalbox forum ^^

(I really need to make some documentation on the WIKI :S sorry)

Sorry to necro this 6+ month old thread but I think it would be better if UXS just parsed the scummvm.ini file (\retropie\configs\scummvm\scummvm.ini) which contains all the information about installed games.

It shouldn't be difficult to parse this ini file and grab all the game names and paths from there. It has the benefit that the descriptions are the same for everyone (ScummVM always uses the same description for each game variant) so matching by name alone should be no problem!

Hashing ScummVM games does not work well, in my experience. There are far too many different variants of each game (compressed/uncompressed/stripped of extra files, etc.). If you use the values from the .ini file you can forget hashing entirely. ScummVM knows what the files are already.

My scummvm.ini file is below so you can see what I mean.
