I found an online site listing and showing pictures of Commodore VIC-20 cassette tape format games here
http://vic20tapes.org/index.php
I noticed that none of these tapes are listed in the VIC-20 section. I bought a system from ebay for $23 after shipping and it included some games on tape and some on cartridge. I was also able to find a separate tape drive from someone else for $30 so I would be able to play these games on my new VIC-20 system.
Nevermind the details, but I just wanted to point out that these tapes do exist and was wondering why they were not in the database on this site or even on the rival database site http://www.allgame.com
Speaking of which, how accurate are the allgame.com lists when compared to the digitpress list?
