At TheXTech-based games, you can easily replace the "
graphics/ui/MenuGFX3.png" file with anything other that you want to use as the URL at the bottom of the menu screen. You can use the texture of any width or height, there is no limitation. So, if you develop your own custom game, you may want to put something like even longer
The reason why the "wohlsoft.ru" is here is that TheXTech Project and assets were hosted and developed at the WohlSoft community where TheXTech's home is (together with Moondust Project and SMBX-38A).
P.S. In the past the "supermariobrosx.org" here was, but people suggested using the "wohlsoft.ru" URL here with the same point.
