Hi,

Is there an easy way to get a fast stable timer?
Right now I time everything in my games on the
1/2 second timer. I do all computing at high
speed and drop it to slow speed for busy-wait loops
to save a little power. I tried using HALT, but the
1/2 second response is too slow.

On other systems (Lynx, NGPC), I do busy wait
off the vertical refresh clock, but I don't see
access to that on a VMU.

A timer with say 1/10th second resolution would
also allow my game speedup progression to be more
gentle. It is rather abrupt going from 1 second delay
to 1/2 second between waves.

Harry

Wow! You have a wealth of useful information on your website. I have changed my code... it used to toggle between 600K for computing and 32K for wait loops....
