The company Smallrockets has released a few of their games as abandonware(even giving out license keys to unlock the games, on the website). All you have to do is go to
http://www.smallrockets.com and download the demo file, then the license key(all this after registering with the site). The reason they did this is because they couldn't get the games to run properly on Windows XP. They should, however, run fine on ME. If you have questions about the games that are abandonware, ask them on their message boards. If you have problems with the abandonware games, tech support will not help you. They no longer support the 4 or 5 games that they let you download.
