Star Castle Brainstorming

Posted by cd-w, 20 January 2012 · 283 views

Here is another minor update to Star Castle:
The rings can now move at variable speeds - I have slowed them down a bit in this version.
The ring segment now disappear immediately when they are hit.
The rings will regenerate when the outer ring is removed.
The gun will fire projectiles at you when the inner ring is...

Star Castle Collision Detection

Posted by cd-w, 18 January 2012 · 284 views

After much head-scratching and code optimisation, I finally have collision detection working! In this version you can shoot the ring segments. For now they only take one hit, but this can easily be changed.



I think I now have all of the pieces necessary to make the game. However, I now need to put it...

Star Castle Mines

Posted by cd-w, 16 January 2012 · 180 views

Here is another small update to my Star Castle demo on the 2600:
  • The mines now follow you around the screen. They will reset to the centre if they go off screen.
  • You can shoot the mines, and collisions between the ship and mines are detected (the screen will flash).
  • Ship rotation is now much slower.
There are still a few...

Star Castle Improvements

Posted by cd-w, 10 January 2012 · 204 views

I have made a little more progress on my 2600 Star Castle demo:
  • Ship rotation is slower.
  • Ring colours now match the arcade version.
  • Player bounces off the rings.
  • Centre gun tracks the player position.
The main issue now is collision detection between the bullets and the rings. I haven't yet worked out an efficient...

Star Castle Ship Movement

Posted by cd-w, 07 January 2012 · 319 views

I have made a little more progress on my Star Castle demo. You can now move the ship around the screen and fire bullets, although there is no collision detection yet. The controls are:
  • Joystick Left/Right - Rotate
  • Joystick Up - Thrust
  • Fire - Fire Bullets
I have been trying to match the ship movement with the arcade...

Star Castle Colour Kernel

Posted by cd-w, 28 December 2011 · 360 views

I figured out how to make my Star Castle kernel display in colour. I think this looks much better than the monochrome version posted in my previous blog entry.



The technique was inspired by supercats kernel, but as before I...

Star Castle Kernel

Posted by cd-w, 18 December 2011 · 382 views

The recent threads on Star Castle for the Atari 2600 have been rather annoying, so I decided to see how difficult it would be to write my own version.

It turns out not to be too difficult - I was able to write a basic kernel with rotating shields in a single weekend. I just went for a simple implementation using extra RAM (FA bank-switching)...

Posted by cd-w, 09 April 2011 · 224 views

As many of you will now know, I have been working on a new Atari 2600 homebrew title called Chetiry. This blog entry should hopefully clear us some of the confusion surrounding the project!

Chetiry is a...

The 2600 scene is still alive and well, and there are quite a few of exciting projects currently in development. I have probably forgotten some, but the ones that I am looking forward to the most are:

Hardware:

More Harmony

Posted by cd-w, 05 February 2010 · 92 views

I've been doing a bit more work on the Harmony project recently (together with batari and Thomas Jentzsch).
