An open source VB6 gaming engine which uses DirectX 8 and flat file storage. This engine was incredibly popular back in the early 2000's and spawned a whole community of game developers, including PlayerWorlds which had it's own game section on OnRPG.
Mirage Source 5 has updated the entire code and improved the networking system. This particular version includes seamless scrolling maps.
