Don't know if it is just me but I find the scrolling or probably the game speed to be very jittery on my ks2 machine. It slows down when firing for example. But when not a lot is happening it speeds up quite a lot.
Compared this to the youtube footage from ks1 machines from 2 years ago and their scrolling seems slower but stable. Tried 50hz and 60hz, didn't make much of a difference in stability. Slowing down the next to 14mhz remedies the issue somewhat, but probably makes the game run too slow overall and it seems to reset to 28mhz on every new game start, so is not a fun workaround
am i missing something or is the game just no longer working that well with ks2 machines or newer core versions or something?
