I had started a project some years ago but lack of experience and know how resulted in a buch of files of a beginner that tried but ended up nowhere.

It consists basically of a Table file (+1000 characters), excel spreadshet with some research, offsets, class and names traslated, some graphics changed, offical websites saved and etc, but no tools or codes of any kind.

What to do,simply exclude like it never existed or there's someplace to put those things?
 

May I include a scan of the manual?

I would say ignore the previous (yes I see the :p. :p ).  Use the abandoned projects and why not include scans of the manual?

The few projects I'm dead on serious about, I've bought.  I do with to translate those manuals and boxes as well whenever I can actually finish said projects.  Why?  Because I think it would be nice for people that haven't played the game to get the background information, the controls, etc in those manuals.  That's me though.  I'd just like to see them for completed projects...makes it feels more complete.

Aaaaah.  Good point. 

Don't do it.
