Space Raid (2600)

Recommended Posts

Hi everybody.

 

For years I've wondered why one of my favorite games got a so bad adaptation to Atari 2600, but it was because of limitations or because of lazy programmers?

 

So I wanted to do a full-fledged game as allowed by my programming abilities and as far as I could push the hardware.

 

I've decided to stay inside the 4K-limit and also I intend to not "abuse" of flicker.

 

So here it is a preview version I've programmed since last week, bug-ridden, some features lacking (like tune up difficulty) and still no collision with enemies or bullets :), the only way to lose a life currently is by fuel running out. Otherwise than that it is very close to my idea :D

 

Enjoy it!

 

Feel free to comment about it. Another thing, I only have tested with Z26 and I don't have tested it in real hardware, so surely it can fail miserably.

Please DO flicker for the barriers screens. They do not look like screens.

In all my imagining how to do this, I never thought of something this good!

Notice how someone rants about "the 2600 can not do isometric well" and then Zaxxon and Q*Bert get made?

What are the barriers screens? Thanks for your kind words.

 

Nice start!

 

 

 

Thanks!

 

Shadows to judge the height would be very helpful.

 

True! I forgot completely the shadows for the tracking missile and the big robot.

 

That's an excellent start - keep up the good work!

 

Very much appreciated! I hope to finish most of it this week.

 

Very, very cool! Love the 3D perspective. Great arcade sounds. Has an awesome early 1980s feel to it.

 

I passed Yesterday several hours testing sounds combinations until my ears were satisfied, I'm glad you liked the result!

 

Actually I have around 512 bytes free, after collision implementation I hope to optimize it and I've a small list of enhancements I want to do :)

 

BTW if someone could test in real hardware that could save me some time ;)

For some reason I cannot take screen captures with Z26 and my current Spanish keyboard, if someone can put here some nice screenshots I would appreciate it :)

Barriers / screens

This thing.

 

 

I see! I've done something about that :)

 

Well guys, here is another version I've crafted this afternoon :D, now player explodes when touches enemies or bullets.

 

Also I've polished various minor details and solved a handful of bugs. There is now difficulty level selection (using switch for player 1, easy and hard, in hard the enemies shoot more often) and reset button support. 8)

 

This is closer to a final version, I've less than 100 bytes free.

 

I'll appreciate greatly if someone can test in real hardware. I'll do myself this test but I need to build some hardware and dismount a cartridge, and this takes some time :)

Looks and plays nice :)

Maybe you could trigger HMOVE every line and then get rid of the enemy's plane ghosts and the twiggling dots?

Takes some getting used to match the plane's height but I guess that's the point of the game :)

Well done, Nanochess!

 

Is it possible to make the black levels more galaxy like?

 

Planets and asteroids (like you did with the graphics in the blue fortress levels) instead of the white dotted lines.

 

Perhaps a different title?

Zonnax or something like that.

Actually I meant shadows in the initial scenario. This reminds me too much at my trouble (I hated that scenario ;)) with the original "Zaxxon". Even though there was a height indicator.

 

Also, when switching to the surface, the objects and the lines do not move in sync. This looks like either the objects or the lines are floating on the surface.

 

Keep up the good work! :thumbsup:

This has great potential as played on Stella. I agree with everyone's comments regarding 'shadows' in the space section. Personally, I'd prefer the space section to be scrapped as is and just make it another surface. You could keep it black and make out like your flying over the surface of the Deathstar a la Star Wars!

My suggestion is make 2 heights, up (for hit airplanes) and down to destroy things in the floor. So you don't need to worry about intermediate heights, if you press up, you know you're in the airplane area.

Thanks! I'm very tight in the kernel area, I'll check what I can do.

I'm glad you like it! Currently I'm very constrained but I've been thinking in a kind of scrolling space background.

 

I think I'll keep Space Raid, after all the other title using it is a Taiwan cooper.

Ah! finally I understood you. There is no much that I can do... I'll think about it.

I think the current state is more fun than having only 2 heights.

Definitely. I am sure there will be a better solution for the problem.

Also Rainbow Vision and Suntek used this title:

http://www.atarimania.com/game-atari-2600-vcs-space-raid_12818.html

 

Both official releases.

 

Keep up the good work!

 

This could very well become the Zaxxon we all wanted for the VCS.

How about Space Raid X? Something that resembles to Zaxxon. Or 3D.

 

I would not leave the name as it is now. Else many people will miss the game, just because they will confuse it with an existing one.
