Update 2025.12.31: Download version v0.1.9b
(this is a quick snapshot of a work in progress)

What's new:
+ accurate RWXFTV access counters
+ hit count map (a heat map, to locate the hottest activity in memory)
+ cpu boost map (with 2 states to avoid the complexities of the previous 3-state)
+ cpu state map (distinguishes code,data, pointers to code, pointers to data)
+ the .hack file format supports now block comments /*...*/ and address ranges:
    -0..2ffff          # disable boost everywhere (RAM,ROM,MMIO)
    :400..7e7 20       # clear screen
    :400..7e7 4d 4e 20 4e 4d    # fill the screen with a pattern
