I've already commented that because the handhelds use a crystal to set the clock speed, they always vary making multiplayer such fun to code. Has anyone run a timing test to find the slowest one as the master. In that way, the other machines will occasionally drop a frame. Is choosing the fastest or the slowest the best stratergy, or does it simply not matter? Opinions please... With thanks, Sean ;-) PS please be gentle, I'm a super-n00b!!!
