I'm not talking about one-off bargains (I've had them too), I'm talking
about market price.  E.g. tell me where I can get a C64 (modern white
style), and a 1541-II for $80 (say I want 5 of them).  Sydney area too.

I really don't know the fundamentals of games, and I'd like to understand
this for the C64 before attempting to port it to the Amiga.  I have 3
copies of the thing on cartridge!  It is the ONLY two player game worth
playing. Although you get points for killing the other person, you can form
a "death pact", and agree to only kill grooblies.  In some
situations, you can stand back-to-back and blast the buggeries to buggerie.

 PE>> How do most assembler programmers handle bullets on the C64?  Like 70%

 ES>  How do you mean?

Well I don't imagine that all 30 bullets on the screen are individual
sprites, and I'd like to know how they can move otherwise.

 PE>> I'm sure C64 games use more than 8 sprites.  How do they generally do

 ES> Fairly simple. You make a raster interupt between the first 8 &

And how are you going to do sprite-sprite collision if that is the case?

BTW, you've made the comment that Wizard of Wor is a fairly simple game. I
have done a lot of programming, and written a lot of programs (eg I have a
full suite of public domain CRC routines, and am working on a mailprocessor
at the moment), but games have always been a mystery to me.  And seeing as
I don't know how to do them, I imagine that they are far more complex than
the things I write, and would thus require about 200k for Wizard of Wor,
instead of the 16k it is written in.  BFN.
