RE: Star Castle on Asteroids Deluxe?

I spent about a year writing it (off and on) and it's been about a year
since I've touched it.
Everything was going along just fine, until I started working on the
collision detection routine. When the ships get close to each other, I'm
checking several segments in one ship against several segments in the other
ship and every check has to perform several multiplications (which is one
instruction the 6502 doesn't have). So, (several segments)x(several
segments) = lots of checks, and it slows things way down. This was one
reason I was looking into possibly using a 65816 or a 65802 because they
have 16 bit registers and would handle the multiplication faster. Another
thought was to add an external math co-processor and let it do the number
crunching.
I graduate (finally) in 2 weeks, so I hope to be able to get back to working
on it again.

ps. I've also been writing a tank battle game where the screen is split in
half and each player drives through a scrolling maze (that's all I've got so
far).

Hey, this is great! Quite true to the original. I ran it in MAME and it
was really slow, and ran it under Retrocade and it was full speed. Looks
cool! Are you planning on completing it anytime soon? ;-)
