Hello PyTFall!
I have recently checked out this project trough github. I had played the released Alpha this summer and wanted to try the newest developement version to spot bugs, test new features and enjoy the game.
I have set up a copy with a few RandomGirl and UniqueGirls pack as explained in the "Want to help? Read this!" thread.
I had a few issues with the RandomGirls. Since the downloads give you the datafile and image folder directly, I put them "as is" in the rchars/ folder. It is by luck that I figured out you needed to put them in a "pack" folder.
You could prevent this issue by adding a .gitignore in the chars/ and rchars/ folders and remove these folders from the topmost .gitignore. More informations
here. This setup would also allow you to track the important characters (Naruto and One Piece girls) while still excluding other packs in the .gitignore.
An other issue I had was with CherryWood's Hinata: there is an image that is not tagged correctly. it is a long string of hexadecimals without separators, starting with "62ff66" if I remember correctly. I haven't made datafiles for Sakura and Tenten yet, there might be misnamed files there as well.
@DarkTI: your Naruto pack was removed from MEGA, can you reupload it?
TL;DR: I started this post to ask for help seting up the game but ended up solving them. I now have a working game to start testing and bug hunting. Is there anything in particular you would want to be tested?
