It seemed interesting, so I took a bit of everybody's work and here is my attempt with a novice. ➡
Also, my take on asking for a release. It's basically won't happen, for several reasons : Rendering issue:
While the sprites can be used in 3D space (it's simply using UV coordinates, so it's basically free), the UI doesn't support scaling whatsoever; your characters will stay giant in status and skill windows, it's not negotiable. Performances:
My novice has height time more pixels than the original sprite and 4 times more colors. I'm sure I could write a tool to reduce the color numbers, but it wouldn't change the fact that crossing through Prontera (or whatever is your capital city) with this kind of sprites would make the vram requirement explode, possibly beyond the 32 bit limitation of the client. And I'm not even talking about the palette system breaking.
Reality check:
Would you even see it? This is a 1080p screenshot of RO, with my upscaled novice right beside a real in game novice.
Can you honestly see the difference? Probably not a first glance.
So, beside higher resolution (1440p and 4k, basically) or in a more zoomed in scenario, this doesn't really bring much to the table. It's just a nice exercise to learn a bit about AI upscaling, I spent the whole day learning, and I'm quite satisfied with the result for a total noob.
