Sadly, I didn’t save most of them and I couldn’t get the .swf files working when I try to open them with an offline flash player, due to a DRM (or something?). (Because whenever I try to open them, something like “This game is playable on Gotmail only.” message appeared.) Then as I said before, the website is not reachable anymore. So, if the games aren’t archived somewhere by someone, there’s no way to play them, except some well-known ones which are on different flash game websites.
Summa cum laude.
