I think you mean de-crypted image (and S-DD1). The shots you see there were pretty time consuming to extract through the S-DD1 and there are many images in the game and finding them all is a very formidible challenge in itself for S-DD1 games because they are scattered all over the ROM. So without some other breakthrough it's not going to happen anytime soon.

That said, the chances are much better today than they were yesterday that will see a breakthrough that will allow emulation. I say that because we (Dark Force and I) have recently developed a method to allow us to run some test patterns through the decompression circuit of the S-DD1. My gut feeling has always been if we reached the stage where we could do that we'd be able to solve the compression algorithm. My time constraints are the main thing delaying this project right now.
