 Started in 2013, continued in 2017 and finally restarted from scratch
 in April 2022 and finished within a few days. Demo code is quite OK
 for its day, there were annoying sprite problems though. These were
 caused by uninitialised sprite pointers in the copperlists (sprite pointers
 were only set for sprites that were used, all others remained in random
 state causing ugly glitches). Other than that there were lot of wrong
 DMA settings (almost all parts enabled all DMA by writing $ffff to DMACON)
 and the usual replayer bugs to fix.
