A while ago, I started playing with the delights of ASM on the Vectrex. Quite fun and a nice little diversion.

Because I doubt I will go any further with the two 'playthings', I decided to upload them and share.

(if anyone wants the source - just shout)

Ok, the first one I did was a little ship moving thing.

Use L/R to rotate the ship and press button 1 and 2 for fire and thrust... Yep, thats it.. lol.

(also, I never did work out a nice way to slow the ship down as a percentage of each speed vector)

The vectrex .bin file is under the picture.

Then, the 2nd one was actually getting more like a game.

It's a 2d Tempest. The code already handles many aliens, all detection, the line thingies, and such. Though, in the demo, I only present 2 aliens.. lol

L/R to move and button 1 to shoot.

Just to also say, in the source there are some nice routines. For one, the vector score code is handy and used in both demo's. Also, this has a nice adder as well that auto adds to the byte stored score. Anyway.... on with the show.
