Phantasmagoria

OK  so i went hunting for some older games.  Ones i remember either playing or watching Others play.  I found this sight gog.com which not only has Phantasmagoria, It has the Sequel, and the Myst series.   :)  So...I’ve been amerced in the game of Phantasmagoria for a few days off and on.  I'm also hunting a VERY elusive game called Obsidian  http://www.amazon.com/Obsidian-Pc/dp/B00069EZ42  I played it in 2000 ish.  I'm skeptical about purchasing the game on disk however since my PC may not be able to run such and older game.  :(  It currently isn't wanting to run a game called Shivers.  

lastly i keep looking for the ROMS and Emulators to play Pokemon, Legend of Zelda 1 & 2.  I've found a website or two that run them off their pages, but i'd rather be able to download them.
