I am currently working on a game for the MenuetOS. It's a rich 'Snake' clone.
I am trying to make a timer, but getting the system time (0x00SSMMHH function) is returned at a great interval - it is updated at a seconds time, and the delay function is not suitable since it prevents the user from input during the delay. Do you have a suggestion?

And ,also, is the only way of drawing single pixel transparent images through custom proc that uses setPixel for every opaque pixel?

There's function 26-9. Read the docs for more information.

Thanks, I did not suspect it could be in 26-9, I did read the docs carefully, though.

Maybe you need to try 23rd function.
