I will include them in the next update on the render_toolkit, and throw in some basic instructions in the guide thread.
Beware though, as you will still need to buy all the relevant assets to be able to load the save file correctly, and that can get pretty expensive quickly. Especially for Denise, who is a mix of assets from multiple different characters. (on top of buying the location assets). You will also probably get a very long list of errors about missing assets for every single character morph I happened to have installed at the time, even if they weren't used.
The logistics of merging multiple sets of images into the same opponent/outfit are a bit messy too.
Stripe's approach of starting out with his own character is probably a lot more sensible, since he was able to go with a mix of free assets and things that happened to be on sale that week.
