A texture pack i created over the months that fixes the ugly stretch that this game applies to it's textures when playing in any aspect ratio other than 4:3 (i couldn't correct some of the textures due to the way the game handles textures, like the battle hud for example).
The pack is still not completely done, will finish when i have the time
