Been working on a cpc version of atic atac - classic game, never understood why there wasn't a nice cpc version (probably a bit early in the cpc's life?)


There are a few sites out there which list the data structure formats, etc, from the spectrum code - and they've been really useful.



I love mode 0, so it has to be that - but apologies for my attempt at graphics, I'm clearly not an artist - my philosophy has been get something vaguely recognisable and move on. The other issue is that I can't dynamically rotate the background items like Ultimate did back in the day (as mode 0 pixels have the chunky aspect ratio), so they have to be drawn twice.


Interestingly (to me at least) the room outlines are drawn as lines, and I found a nice algorithm on here for that here:
http://www.cpcwiki.eu/forum/programming/fast-line-draw-in-assembly-(breseham-algorithm)


Couple of questions I've been thinking about though:

       
  • Is this likely to be served with some kind of take down notice? I don't want to go too far if so.
  • Depending on the answer to 1, would anybody be interested in doing some nicer graphics for this (as I'm using the speccy data structures and map, there are certain restrictions to consider size wise).

This is looking really good!
Is it an asm project?

There's been a few C64 and Atari-8bit ports of Ultimate games in the last few years and I've not heard of any takedown requests - the only recent homebrew I've seen subject to DMCL takedowns is hte C64 version of Super Mario Bros..

Forgot to add the link to the code:

The C64 saw this year an excellent version: https://csdb.dk/release/?id=188753

I don't think you'll have any issues; keep going!
Released The Return of Traxtor, Golden Tail, Magica, The Dawn of Kernel, Kitsune`s Curse, Brick Rick and Hyperdrive for the CPC.

If you like my games and want to show some appreciation, you can always buy me a coffee.

@40Crisis wrote a program to convert Jetpac to the CPC in 2014, but he didn't include any of the actual Spectrum code for copyright reasons. Despite that, there are copies of this version out there that do contain the original code, and none of them have been taken down.

That's a really cute project! I loved those old Speccy games. Mind you, my first computer was a ZX Spectrum with 16k. Tranz Am would also make a great conversion to the CPC. Maybe when I am retired ..

Hey matey, Steven Day of the Atic Atac C64 conversion has sent some artwork over to help :)


QuoteA) Rare will not issue a takedown unless he tries to sell it. retro freebies are classed as "fan art" to them and B) pass these on to him and see if they fit his template.

Ah thanks Neil79, that's fab.


It looks like these are a bit higher res than I can use, but I'm hoping I can use them as a basis for a mode-0 version.

TotO

The MODE 0 doors graphics have the same resolution as your, except they are more colourful.
Sadly, it was posted as JPG, so the graphics was destroyed by the image compression...
Here an example that how it fit... It will be amazing if he can do graphics for you! :)

Ah ok - in that case if we can get them as png's then we might be in business  :)

That Alien 8 screen... WOW.
It would look absolutely amazing with the CPC palette.

Great! :)

Yes, it will be really nice to have your atic atac port with colourful graphics.
The game will be metamorphosed to an authentic MODE 0 hit!
(probably you will have to fix the palette to match next)

A few screens with some of Ste's graphics in, they're great.




shaymanjohn

More excellent work from Ste.

It's really great ! This is not the same game anymore.
