I've been looking around and they all seem to add custom content or change things. Even Smokey's Vanilla+ isn't actually vanilla, changing many backgrounds and character models/textures. I'm just looking for high res vanilla textures, nothing more.
@Ashenbubs is currently working on a very stellar one. I don't know how far its gotten or how accessible it is at the moment though. I'm out of the loop.
Hello I'm the author of the dolphin PSO HD UI pack. Some 3 years ago I ported what I had redrawn for Dolphin over to a BB client, got the pack to a decent state then got frustrated by the tools that were publicly available for modding BB and kinda moved on... I may try and get the tools set up again to get it ported to Ephinea if there's interest.
