OMG! This is awesome! Yes, I used the captures, I tried to search on the internet, but I didn't find anything. With the original graphics, it would be much better. I'll have a look asap. Thank you!

http://st25sprites.neocities.org has all the details for the graphics I extracted (including things like depth maps for the bridge if you wanted someone to be able to walk around!). There are a few things I know that I'm too lazy to upload at this time (color palette data perhaps most interesting to you) but I can if you'd find it helpful. Each subsection contains a zip file of the extracted data, so you can download every sprite used etc.
