Title: Crownland conversion from Atari
Post by: XeNoMoRPH on 07:35, 02 May 19
I have recently seen these videos on youtube, it seems that someone is converting the game Crownland to CPC , Does anyone know anything about the project or know its author?

That looks really awesome! Sorry I have no information about the project.

That looks like hardware scrolling with the paralax been done with software techniques. If that is the case then it is very impressive.

That looks great indeed!


Not to sound picky, but Crownland is a game for the Atari 8-bit computers, not the C64.  ;D


I’ve played it a lot on Atari and I can say that it’s a great game!

You are right robcfg, Cronwland is a 128k Atari game. I completed it some time ago on my 130XE, but it's not very rich in levels.

Don't know anything about the conversion but it sure looks impressive. It's hard to get a parallax effect like that without a purely software scroll (and that in itself is tricky), so I'm curious how it's being achieved.

I am sorry I don't see the point in creating a 1:1 port of this game to the CPC, since I don't feel it is going to match the original version. I don't see 'smooth scrolling' and 'non-stop ingame music', both features packed on a decent game screen and not just on a small window, as the biggest strenghts of most CPCs games; besides, Crownland does not work on any stock Atari A8, it requires at least a XL/XE system upgraded to 128KB of RAM, so it may be more fair to port it to the Amstrad Plus range.


A plain CPC version could take advantage of more enemies and/or moving platforms on screen (as it doesn't need to rely on a limited number of hardware sprites), so it would be harder (and maybe slower) to progress, or could even introduce puzzles to keep moving on the stage, but it would mean to design a different gameplay -what would be great, but would make it like 'Crownland 2', not just 'Crownland'.


Atari A8 games I would love to see on a CPC, with updated graphics and so? Drelbs, Realm of Impossibility and the first dungeon crawlers with close to text-mode aesthetics. I can't see a Yoomp! port to the CPC, for instance.

It's true .. I've been wrong with another game I had in mind about C64 and I've messed up haha  :picard:

Hi !
I'm the author of this preview. Initially, it was just an attempt at parallax scrolling, but the project progresses.

Good intuition :) 
Hardware scroll is used for front tiles, and compiled tiles are used for background and water. I hope i can show more very soon.

Impressive! The multi-plan scrolling is a real plus, and was certainly a bit tricky to do. If you need help/advice for the music/sound, don't hesitate to ask (check Arkos Tracker on my signature if you never heard of it).

Hi,
The two video preview are astonishing ! :)
For the front tiles, is it byte hardware scrolling at 25 hz ?Won't you need the scrolling to be slower when the character starts to walk ?

Thanks you, it's very nice.

Arkos Tracker is installed on my machine. Just, i'm bad with soundtrackers.

I'm glad this preview pleases.Crownland on Atari 8 bits seems, to have scroll at same speed than the preview, but i could be wrong.

It depends on what you want to do actually. I saw an Atari ST version, I guess you could use the same music? In that case, you can use Madram AYC player (from the YM stream).
If you want something more specific, you can you can still ask for help.

I didn't know this game. Seems to be a mix of Mario / Wonderboy (snails inside !). Graphics are nice, animation is good but the music is CLEARLY too short and not very inspirated (even if for an Atari XL tune, sounds are good). If you plan to do an Amstrad CPC port, you should change this !

It's a little early for me to project on what the music will be. The plan was to convert it from Atari ST version, but again it's too early.
I still have work to transform a parallax scrolling demo into a proper game. And... I'm slow.

I would be sad if the game music is changed.


Maybe improve it, but definitely not changing it. The tunes are short but catchy.
Title: Re: Crownland conversion from Atari
Post by: TotO on 13:00, 04 May 19
It will be not the first time that a 8/16-bit game do not have the same music from a system to an other.
I do not see any issue with that if it can be better and in the same spirit. (Cybernoid, Deliverance, ...)
Title: Re: Crownland conversion from Atari
Post by: robcfg on 15:10, 04 May 19
As usual, it's a matter of taste and it's gurneyh's call.


Just saying that if you're used to the original tune, changing it drastically would feel weird.


But that's my 2 cents  :D

Yes Rhino, it's my first project on CPC. But... I take advantage of the help distributed on forum :)

I hope you manage to get the game finished.
It takes an enormous amount of time and talent.

I think the development is paused for, at least, a long time.

Indeed, the project is on hold.
Crownland is still important to me, so I hope to finish it, even if it was originally just an excuse to start programming on the CPC again.

Coding a scrolling is different from coding a game :)

Can you share a little about the programming method you used for the scrolling? It looks amazing!

Hi,
A small step forward for this project:

Great code!!! And this is something I only say very few times ;-)
The GFX on the CPC can of course be better than on the Atari (in some way). But I assume they're well done palace holders.

Awesome to see a scrolling game. I'm tired of that static kind of games. Go on! This will be really great!

Of course! :)

For the foreground, it's a hard byte scroll using register 3 of the crtc. Very standard technique.
For the clouds, and other background scenery, it's pre-shifted tiles per pixel. A soft scroll in fact. I just take care to display only in the holes left in the foreground.
For the animated water, these are also pre-shifted tiles.
It seems to me that the technical limit is no more than 7 lines to be redisplayed so as not to fall below 50hz.
The target is 25hz in double buffering, so there is still one frame left for sprite display. They are small, and it was fine.

gfx are taken directly from the rom, thanks to the author of the conversion on Atari ST, a version which is also on break. He had kindly provided me with the data from the rom, which he had received from the author of the original game.
A redesign would be necessary.

Indeed, platform games with scrolling are rare nowadays.
We see a lot more games with a static screen.

So Basically you preloaded the next shift for the scrolling correct? Did you hold the info in memory to achieve that speed or was it read just before it was needed?

I don't really understand the question, but yes everything is in memory, the demo only runs with 128kb.
One thing is that the preshifted tiles are compiled. That is, we don't read the data to write it, we just write it.
I hope this answers your question. :)
