Heya Guys,

Thanks a bundle for the memory info! It feels almost luxurious to
have all that memory all for my game... :) Imagine I was working with
the bytes inbetween in interupt addresses if they weren't used by a
system variable (just in case). You can imagine I was left with about
16 bytes of usable memory... Not easy...

Anyways, I've got part of the game running now... I've got my
scrolling 'sky' and 'floor' (don't think too much of it) and finally
my ship that moves around freely in this world... Now, question time
again... I am currently working in the 600MHz mode for extra speed.
I've read though, that this uses more battery power than the subclock
mode. The question is, how much?!?

As of now the game is still hella-fast, but then I've got no enemy
routines and no (and thats the real bitch) sprite collision
detection. Then another this is, if I want to add SFX or Music, as
far as I know I won't be able to change clock-speed without the sound
routine making strange-glass-breaking noises.

So anyways, the question... Is it okay to make a game that runs in
600MHz in the entire game, or would this use up way too much battery
power? Apart from that, is there anyone that thinks all the above can
be done (including sound) in subclock mode?

Your feedback would be appreciated...
