http://www.adventuregamestudio.co.uk/site/games/downloadcheck/. This only shows games where the download has been reported as broken though. Automatically checking all the links the way I did the images would take far too long.
The broken download links list contains only reports from users/members as far as I know. In each entry the link '
If the download link or mirror link doesn't work, please report it.' --> then confirm broken link.
I'd suggest let's fix as many as we can for now and then discuss how that might be avoided in the future. (e.g. Some kind of automated e-mail posting system once screenshot links and download links are reported as broken and confirmed(!) to be broken or something similar. Storing them locally etc. and so on and so forth)
On a kind of related note, I got 5-6 wrongly reported broken download links - the download sites just took a while to load the file and/or you had to click a button or enter captcha and such.
edit: Though I do agree with you Leon. In order to make this effort seem lesser like "Sisyphus playing ball with the rock"

, it'd be very, very usefull if someone would be able to update the AGSarchives storage database alongside. Especially, for the 'long lost' games section - some games people were able to recover (now & before), but files on outside servers will continue to expire, those games will disappear again and we can start all over again. (Please, don't get me wrong Peder, I know you're updating the database and I know nothing about the 'background logistics', it just seems like a Herculean task (OK, OK, enough with that Greek stuff already!!

).
