Hi, as an old school BG player and infinite lover of this game, I had a nostalgic urge to see the old UI in the game. It may be low-res, but I still find it very nice to look at. Texture resolution was never that important to me, neither do I think it defines the quality of graphics. Texture desing, not full HD resolution defines it´s quality.
So I just tried to put old BG textures to EE main menu and here is the result. I think it looks nice, if I have enough patience, I would try to remake more game windows. It is combination of textures from vanilla BG and Tutu GUI for BG1.
Also, I´m an amateur, so don´t expect miracles
There are two versions. One with Tutu wooden trim and one with just pure texture.
