I have seen the mod (Powder And Cartridge) but I dont like new sounds and some skins (also really long game loading, about 5 minutes), so I tried to deconstruct the mod. Every time I tried I just broked the game (or bug it).
About the standalone UI mod I have seen link to moddb on some russian forum, but I also get to know from there that it was deleted from the site because some features was considered as cheats....
But I still looking for it in deeps of the internet
