Ha ha - I found that site in the first place because my wife saw me playing GoldRunner on KDE and freaked out. "Oh my gosh - is that LEMMINGS!?" That, of course, made me freak out. "You know about LEMMINGS!?" So I just HAD to play Lemmings that day.
Wow! I really like the attention to detail. You can change the desktop wallpaper with the genuine Windows 3.1 tile images, you can create and save files (which download to your actual computer), wildcards work in the file selection dialog...
Of course not everything works, but this is a lot of fun.
xyzzy <shfit>+<return> doesn't work in minesweeper, which was the first thing I 'tested'. I also tried xyzzy <return> <shift>+<return> because that's how I remembered it. (http://en.wikipedia.org/wiki/Xyzzy)
The user string for the browser is whatever browser you happen to be using at the time. In Firefox 3.5.7 I get 93/100 on acid 3 from the internet browser in the app.
It's odd that the address bar in the browser reverts to 127.0.0.1 no matter where you are. Does that happen to anyone else?
Getting the current URL of an embedded frame showing a page on an external ___domain is (or at least should be) impossible due to restrictions on cross-site scripting. This is the same reason why when you view a page that's trapped in a Diggbar-style frame, if you click a link inside the framed site and later close the "bar", you get redirected back to the initial site. Try it: http://digg.com/u3L7UJ
Timer stops when you mark all mines with a flag not when you uncover all safe squares. Also, left+right mouse function is missing (reveal all squares next to current one if mines have been marked).
When you right-click to mark where the mines are, the browser's popup menu comes up and you have to click again to get rid of the menu, thus eating up valuable minesweeping time. Can that be suppressed?
It's mostly Javascript and good ol' html/css. You can browse the source of the site with your web browser and check out all the JS goodness. There has to be a server to host the site, but I don't think it plays any other major role.
Also, this reminds me about how I used to carry around MiniVMac (a Macintosh emulator) running OS 7 on a thumb drive to keep random notes and drawings. It would be kind of cool if you could sign up an account on this site for that purpose.
