Improvement over https://tasvideos.org/2133M
Uses PCem 17+st-1 with the Early 90s package, with the game placed onto a CD.
Main improvements come from doing "corner boosts" more (old movie did not do them in all possible places) and reducing the score counter (to reduce score countdown time at the end of a level).

Note: At a glance this movie appears slower than the linked publication, even after substracting the longer DOS terminal part. This is because of an inaccuracy in PCem, causing the internal refresh rate to be lower than expected. After taking that into account, this submission is faster than the linked publication.
feos: Claiming for judging.
feos: Indeed the previous movie didn't seem to care about the time score tally takes, and it takes an extra frame for every 20 points.
If we take this movie's gameplay time from the encode (197.95 seconds) and adjust it from 69.3923791043Hz that PCem uses for DOS's 70Hz mode (25.175MHz clock) to 70.0863028953Hz that it's meant to be, we get 195.99 seconds, so 1.242 seconds of gameplay improvement over the old movie (which was 197.232 seconds long in gameplay). Now PCem st1 runs at 100fps at all times, but realtime duration is still more or less representative, aside from requiring a tiny speedup.
Accepting as an improvement.
Note that firmware for PCem v17 for some reason has a different
pb570/gd5430.bin file that doesn't sync with this movie. It requires v16's version of it, which is what our early90s setup also used.
