Screen is flickering a lot - no, not because faster CPU, but some strange color value changes in code, in cycle. + there is V-sync for making it running not faster on faster machines.
Too bad, because seems as good and addictive.

GEMS

by Martin Brownlow

Introduction


GEMS is an unauthorised conversion of
Diamonds, a game for the atari 8-bit,
which was written by Simon Hunt.

The aim of the game is to clear each
screen of all the gems it contains,
while avoiding the bad guys.  When you
collect a cluster of gems, the number of
gems is added to the HOLD value at the
top of the screen, and also to your
score.  If you go to the top of the
screen holding some gems then the screen
will flash and you will get double
points for those gems.

There are 3 bad guys per screen; BRIAN
the BLOB and THE DEMON are always
present, and the remaining is one of
PHILP the FILLER, THE FIREFLIES, THE
EYES or SIMON the SNAKE.  You must
complete each screen 4 times, once with
each bad guy, to progress to the next.
