Revisited: now a pure 8086 version (previous ones require 186 for push
value; rol reg,num; and pusha/popa)
255 bytes: still 1 long jmp and 4 lots of push pop cx, so maybe a few bytes
still to squeeze out. Oh, scoring is now unrestricted. No sounds or
speedup, just std play with csr keys (and Esc)
-> d 100 l100
