First of all, that's EC, not KR

The tileset is clearly not the KR one. (Use my UO:Reader to verify

)
I do have some KR screenshot somewhere in my HDD.
The UI, as you well know, can be changed (and you did a great work).
What did not changed (since 2007) are the rendering capabilities of the client(meaning both shading and engine), the map i made could not be handled (crash + memory leak + crash + leak + unability to load map blocks on time).
Please notice this was not map depended, it was made obvious by my map only because the statics density was higher than the classic maps).
Btw i just ran into those screens and felt a little sad for all the work that has been done and it's gone wasted!
All the KR tileset -> gone, or at least not usable atm.
The EC is always used as secondary client on all official posts AND it did not see any major update until 4.0.35, which is basically a UI update. ( i just found out ^^ )
