The OpenGL code now uses 32-bit textures. This is required for 

blending in conjunction with phosphor effect.

For the Chetiry scheme, when loading or saving the 64 byte score
table, we now ignore the first 4 bytes (as specified by the
documentation).  These 4 bytes/addresses are actually a type of hotspot.
