OpenGGS A new version was launched (0,100) and in collaboration with the author of OpenGGS we offer you the updated version for the Dreamcast.
The main novelty of this version is able to use the original graphics of Giana Sisters of the C64 version. We thank Manfred Trenz (original creator of the graphics for the C64) to give permission to use the original sprites.
Other features remain from the previous port (option composed music. Mod and saved in the VMU). The previous saves are compatible with this version.
