I've been working on a game for some time now (Bomberman, MAYBE FutureDisk
will show a demo of it on the Bussum-fair) but I'm having some troubles with
generating random numbers. I'm now using the refresh register which I add to
the previous offset in a look-up table, but it isn't random enough

In stead of adding 'R' to the previous offset, try adding the joystick
inputs. Or rotate

In stead of adding 'R' to the previous offset, try adding the joystick

the best way of creating random numbers :)
A bit of XOR'ing here and there is not a bad idea either.
That sounds like a good idea too. I'll

the most "random", so use those for the result.
Thanks Maarten. And yes, I knew that the middle bits of R

I don't think so, because the time it takes to repeat it is constant so R
will be increased with the same number all the time.
