The TAP and TZX in the entry for Super Sinc 4 (Anno 2) (1985) are actually the tapes for Super Sinc 4 (1984). (You can tell by comparing the contents of the tapes with the contents listed on the cassette inlay images.)
Which means the tapes for 'Super Sinc 4 (Anno 2)' might be MIA. If I come across them living under some other title, I'll report back.
The latest ZXDB database update will be applied today at 1530 BST. The site goes down for around 30 minutes whilst this happens.
