Erm, I coded it and I lurk here. ;) The colour screen is just a basic double-buffered vertical scroller, but doing both colour ram banks as well. (thankfully that's much less hassle than on c64) The one pixel scrolling is achieved by carefully NOP'ing and DEC'ing $9001 over a small loop, which sets ...

Just a quick one from me, unfortunately not hardware tested this time. PAL only.

A while back I got the Vic to do different char colours on every 2nd vertical line in this demo: http://www.pouet.net/prod.php?which=24332 The fx in the screenshot shows it, each bar has it's own char colours. Unfortunately doing it this way only 4 lines of a character are displayable and it's repea...

Nice job!

Anyone interested in the source for the original? I've uploaded it here:

oops, that should be '64 byte boundries' ^^^^^

Hi, Here's some quick code to do the perspective raster effect. It's also the basis of a 'trailblazer' if you add some road gfx and alternate the multicolours. This is for PAL machines, though I imagine you only need to change the 'nops' in the display routine to get it working on NTSC. sei loop ;; ...

Hi, Yes you're right, Astro Nell used the petscii rom for it's room blocks. Each 8x8 block was defined in 3 bytes: byte1: char rom position low byte. byte2: top 4 bits = colour low 4 bits = x start position * 2 (so you can place only on 2 block boundries) byte3: top 4 bits = block type + char rom po...

Hi,

I just released a demo for unexpanded machines with a couple of screens in. You can download it here:

A little about myself, I used to be a member of Cosine where I wrote the "Astro Nell" game and a few other demos.

thanks, 4mat/atebit
