So I went through some sprite codes and evenly duplicated current graphics to use for buildings that haven't been made yet. I tried to use a similar type of building for the ones I was replacing so they don't look out of place. While doing this I was also looking through all the current content available, even stuff that doesn't make the nightly build. I managed to find a couple more uncoded graphics that were too unique to reuse existing ones, so I coded them and added them in.
I did this purely for personal use to improve the visual quality until 32bpp is finished. It is meant to be a collection of everything I could find and duck taped together to make a 32bpp version that looks as finished as is currently possible. There are still some that I couldn't replace but its mostly not very noticable. I also added a larger GUI grf and increased font sizes with new font.
Now I'm not sure if this is something anyone else would be interested in, but I would be happy to upload it if there is a demand and it is ok for me to do so. I don't know who created most of the stuff I have used or even if it was intended to be released yet, so I'm unsure if it would be appropriate for me to release it.

Edit: screenshots of some of the stuff I coded.
Bank

Park

Second park and statue

Tennis court

Still need some minor adjustments. I found the 8bpp stadiums stand out too much so I replaced both with the tennis court. As far as I can see there are no 8bpp graphics left in my towns for temperate 1950-2000(approx).
