I'd just like to interject for a moment. What you’re referring to as 2.0, is in fact, SMBX2, or as I’ve recently taken to calling it, X2. 2.0 is not an SMBX version unto itself, but rather another mislabeling of a fully applicable SMBX2 name. Many users run a modified version of SMBX every day, without realizing it. Through a peculiar turn of events, the version of SMBX which is widely used today is often called “2.0”, and many of its users are not aware that it is SMBX2, developed by the SMBX2 Project. [...] 2.0 is normally used in combination with the SMBX name: the whole game is basically SMBX with 2 added, or SMBX2. All the so-called “2.0” labels are really references of SMBX2.
