rderooy thanks for the reply.
It's very hard to know those pirate-releases, those with red case are the rarest. I think these were made by computer-shops itselves, so It's very difficult to know where they come from... We have to ask to the owner.
The others.... I have many of them, and since tape magnetic material is very cheap, it's very hard to make a dump... So I have decided to avoid and not to buy them anymore.
Maybe for these it would more simple to find editor even if it's not written but, as I can see, they were distributed in all Italian territory... and so, also in this case I have to ask.
About Armati releases: the person who made them lived in Milan or nearby (Varese?, Brescia?, etc.) and maybe I can find out how contact him.
That msxit.org site is mine, and I forgot to update it, so I own all the missing tapes with a titled listed - I could start scanning covers, and some of them have a manual, too.
Certainly if you want to scan covers and manuals, that would be appreciated. Personally, I would focus primarily on the non-pirate releases for scanning covers and manuals, especially software where we don't have a lot of information.
Also, I noticed your website is missing a two or so Sony Italia releases;
https://www.generation-msx.nl/company/sony-italia/835/published/
Sony's SDE-002 and SDE-010 arrived to me just yesterday, so the collection is complete.
I think that one of the pirated-tapes is from a Sony tape ("lezioni... esercizi..." etc.).
