Is Zwerkules still updating this basic patch hak?
I fix bugs if you find any, but there won't be any more tileset overrides. TNO is covered by project Q, it has improvements and additions. The only tileset I might add roofs to if I get some time is the castle inerior.
The city tileset is so bad that no textures no matter how good they are will help, IMO. The best override for the city tileset was made by Six and the one who has entirely too many numbers in his name for me to remember it '> (s030363l, looked it up).
Even though it is the best I would only use it as an override for making old modules more appealing, because as I said before a simple reskin won't help much, the original tileset is just too ugly.
