Demon Attack

This is a little wordy, but here is my take on Demon Attack.

“Marooned on the ice planet Krybor, you watch legions of erie creatures scream overhead. They hover ominously. Attack and destroy them- or be destroyed! Armed with your Laser Cannon, you confront the ultimate challenge: Survive!

maybe i should try and pick one up then.

i have one for the atari 2600, so i thought it would not be worth getting it for the vic

i used to have it for the intelli, and it was very good on that platform

...again... Why don't you just play the cart image on your real vic20?

How about running me through the procedure again?

1) Copy .prg file to floppy

2) Insert memory in block 5

and that's it for me

How do you make sure the .prg loads in block 5, and what would be the SYS command to use to activate the game?

LOAD"file",8,1 and then SYS64802 should in most cases start the game. Lee suggested SYS64812 which I yet haven't tried, but will some day.

Thanks!

I will try a couple of images, and hope for the best.

I played this game a couple of times yesterday. Before that I
think I only have played it once. It has really nice graphics.
Looks like multicolor in hires! They are using the raster beam
to change the background color on every line behind the
monsters. So the whole display is inverted and the background is
foreground and the other way around. This way they could use
hires and many colors at the same time for the monsters. And they
can even use 16 colors on them as the background can be set to 16
different colors. Very smart and probably a bit difficult to do.
Watch the monsters and you will see that all of them always are
above eachother, except for the small ones that gets split up
into two that always are at exactly the same hight. Also look
at the shoots when passing closely to a monster. This is all
because of how they are constantly keeping track of the
background color changes all over the screen.

My highest score yesterday was 10885.

Thanks to people's tips etc... I got to play this game yesterday on my real vic as well!

Feels weird playing a cart. game off a floppy though.

The people (or person) who worked on this game did a wicked job.

I really like how they make it feel like there are more than 3 aliens on the screen at a time and all that. Goes to show how much thought was put into this game.

That was probably the first thing I learned on vic20. How to load a "plug-in" game (from tape)!

This game is only a 4k cart too, takes only about 11 seconds to load with a diskdrive. Probably about as long as it takes to swap cartridge...
