Thanks for your work, satsuki, great idea! Though there are some minor issues i can report.
So, when i've been using the installer and the function convert dds to png, it seems to freeze right at the end when it finishes. Tried it a couple of times, left it overnight even, but i see that it did convert all the textures in the output folder, but the preliminary setup screen seems to be stuck, and the installer doesn't go past it no matter what i do.
Another issue is when i use the UI upscale, the font seems to have spacing and transparency issues. Letter are very close to each other, and have a lot of bad edges around, which seems to look like transparency issue to me.
Otherwise, great work, hopefully those issues will be adressed whenever you have the time. Also, a question, were any of the textures were updated when packaged? What i did is test the package, though i had your textures installed before you did this all in one package, so there's no need for me to use it now, i guess, other than the UI, so, did you update any of those textures to look better or something like that since?
