Thanks for providing all these great resources. I'm so excited to be able to preserve these games here on RetroFab with your help. I've still got a few games backed up in the queue to finish before I can start tackling the coding on these Sonic games so I appreciate your patience. It may be a good few weeks before I can start working on them. Although I might take some time out to take a stab at SegaSonic since it looks like the gameplay is very similar to Tiger's Snowboarding, in which case it should be relatively easy to put together :) As for additional support, if you're interested I have a new RetroFab related project in early development you might want to get involved with. If you rate RetroFab and leave your email address in the rating comments I can provide more details via email so you can decide if you want to help out.
