I can never seem to dload any games from this site,rapidshare always says the links are invalid for some reason.

Invalid links happen, when they are older and deleted by rapidshare because of copyright conflicts. I even have found Shark's HA3 on this site

I had'nt any problem to download this one

Me also, The DL uses Depositfiles, not Rapidshare.

That one is on a lot of flash game sites. It can be played online here:
