It’s been a while since I’ve done this, but today I’d like to show you how to make the free and open-source version of the game “Raptor: Call of the Shadows” work on Windows XP and Windows XP Pro x64 Edition. Thanks fly out to Srandista, who let me know about this on the #guests channel of my [IRC chat server]. This is a funny one, given that the original game was developed for DOS in the early 90s. While the games’ developer Scott Host gave the source code to another developer going by the nick name [skynettx] to be released under the free GPLv2 license, this version is based on a reverse-engineered version of the source code produced by nukeykt.
