I hate to break it to you, but most of these aren't "unused", they simply don't exist -- they're just things never intended to be read as levels, being read as levels.

Yeah, SMB's levels are encoded in a very unusual manner that tries to use space as efficiently as possible. This means that just about any random string of bytes can form mostly-coherent (though not necessarily beatable) levels. These codes just point the level data at random bytes and get interesting results.

It would be neat to hack the game to make up level data at random...

Other games aren't quite so conservative, so there are many possible values for various elements of level data that just create utter garbage or crash the game. SMB might do odd things like "if object's position is off the screen, subtract n from the position and change it to object type B" to save a byte when using object type B. (I haven't actually looked at the format in detail though.)

The alt attribute should be used to give a short description
of an image; longer descriptions should be given with the
longdesc attribute which takes a URL linked to the description.
These measures are needed for people using non-graphical browsers.

For further advice on how to make your pages accessible
see http://www.w3.org/WAI/GL.
You are recommended to use CSS to specify the font and
properties such as its size and color. This will reduce
the size of HTML files and make them easier to maintain
compared with using <FONT> elements.

You are recommended to use CSS to control line wrapping.
Use "white-space: nowrap" to inhibit wrapping in place
of inserting <NOBR>...</NOBR> into the markup.
