v1.5 handle SNA snapshots (48k only)
v1.51 handle non-standard border colours

v1.7 combined basic loader for 128k & 48k so usr0 mode is always used even for 48k snapshots to help with compatibility, optimised screen decompression code
v2.0 incorporated new 4 stage loader with best in class compatibility, including full AY register restoration. Removed final load to reduce loading times
even further. Retained in-screen loader but adapted to fit with new BASIC stage to reduce size.
