Title: Sonic the Hedgehog, a question for coders
Post by: ParanoiaDragon on 11/04/2010, 09:56 PM
Was thinking today, (since I've been doing some game planning), could Sonic 1 be done on the Turbo, if ALL the tiles were squared off?  It'd maybe be ugly looking with everything squared off, but, that's not what I'm concerned about, just wondering if the paralax(both horizontal & vertical) could all be pulled off that way?

listen it was on the master system.

it can be done on the turbo.

and yeah the parallax would be doable I think.  You'd have to plan very carefully

Yes PD, xavier always works above .

But as many changes was made on game engine, the project progress slowly ..
Several parts had to be rewriten in asm for improving performances.

First level is completed.

Parallax are included of course  :wink:, and perhaps a copper like effect.

The last demo I played of Xavier's Sonic, did have paralax, but it was different then the Genesis version IIRC, that's one reason why I was asking.  I'd maybe have to go back & find that demo again & play it.

It was different in that it used the SMS Sonic graphics instead of the Genesis Sonic graphics. Yeah, it had parallax but the sprites and tiles were from the SMS. I think it was simply because the SMS version of the game ran at a lower resolution than the Genesis version and was "easier" to port somehow. I could be wrong on this though, because it seems to me that the the Turbo can definitely handle whatever resolution the Genesis version was running at.

I remember being relatively unimpressed with that demo last time I played it (a decent number of years ago, now).

There is a version of the demo (11/9/2008 or later) that looks almost identical to the Genesis version, with some good horizontal parallax.  But getting a smooth-running game with vertical parallax, with the sparkly ocean & trees in the background, moving at a different rate from the entire foreground, is too much to ask from the PCE, IMO.  For two layers of scrolling/warping backgrounds, plus sprites, really a single-background VDP like the PCE's doesn't suffice.

The demo I played was definitely dated before 2008. Where can I find the 2008 version?

Yeah, IIRC it was the SMS version I played, don't recall playing one that looked more like the Genny version.
Title: Re: Sonic the Hedgehog, a question for coders

Was thinking, instead of doing vertical paralax, what if the vertical part was static, like the bg's in the PCE Ninja Gaiden?  Would that be easier/possible??

yeah.  vertical paralolx is the hard part.  if you get rid of it, everythings easier.

Verticals parallaxes are not more complicated than horizontal ..

Mixing both, is the real hardest part IMO ..

thats what I meant.  The horizontal is already a given since its a platformer.  Mixing in shit moving up and down is going to be tricky work both art and code wise.

Kind of off topic, yet on topic too... if anybody plans on doing anything else with this demo, or another Sonic demo entirely, I made this quite a long time ago...

It's basically a custom sprite set for Sonic.  I started out ripping the frames from Sonic CD, but ended up using everything from Sonic, Sonic CD, Sonic 2 and even Sonic 2 beta version.  I also did quite a bit of tweaking and color editing in order to get the ultimate Sonic sprite sheet.  I didn't use Sonic 3 simply because I've never been a fan of how that version of Sonic looked.

Anyway, if someone ever makes another PCE Sonic demo, this might come in handy.  :)

This is the first version, it's very very old (and bugged) ..

xavier had posted a build on September 13, 2008 on the Frozen Utopia forum, but he used rapidshare for it so it disappeared. :(

Remember that this demo is old, at the moment level 1 and 2 are finished,and level 3 is close to being finished ..

Oh wow, I didn't expect it to be that complete. This is some pretty amazing work.  I was thinking more it was going to be something more like watching, not fully playing.    Thanks for putting it up.

So is someone actively working on this?
Title: Re: Sonic the Hedgehog, a question for coders
Post by: ParanoiaDragon on 01/15/2011, 07:38 PM
Ok, I remember playing this now.  I hope he is still working on this.  I'd like to see him make Sonic less "floaty", & probably should make the hitbox larger on enemies & coins, as well as getting the 2nd & 3rd bg's to go slower then the 1st bg, rather then faster.  I can't seem to get it to go to level 2 for some reason?
Title: Re: Sonic the Hedgehog, a question for coders
Post by: touko on 01/16/2011, 05:44 AM
I don't know how is the latest demo, xavier was show us the complete first level ..
I think he will make an announcement when it's ready ..

But it's always on rail for sure, and he's working hard on it.

Shouldn't the sprite be modified? Sonic --> Zonik

Oh, crap. Zonik exists (http://images.wikia.com/sonic/images/e/e4/SonicGamebook_Sonicvs.Zonik.jpg), and he has nothing to do with Zonk or the PCE universe.

[sourgrapes]Zonik was a juvenile, stupid name anyway.[/sourgrapes]

You'll find a hidden spring if you fall into the second sewer.

Oh, wait.

I'm thinking of JJ & Jeff.

Man, so far no one's mentioned my music in the demo, it must really suck! :D  Seriously though, I love the Greenhill Zone track, & it surprises me how nice it actually turned out, especially with it being a few year old, as I like to think my skills have improved somewhat since then.  If anything, it's an ego booster, which is good, as I tend to bash myself often & feel like I'm not capable. ](*,)

There are just 2 jewels to get.  The sign spins when you get to teh end of level1.  I don't think the demo goes any further than that though.

Paranoia, I would have commented on the music but I played it on Hugo so I wasn't able to hear the OGG audio.

I just downloaded this, and tried it in ME.  Everything looks sweet, and the music was just fine Paranoia! :)  Hopefully this will be completed.  I always loved Sonic, and to be able to play it on the Turbo, well thats just awesome.  Has anyone tried this in actual hardware?  I am thinking of doing just that. 

EDIT:  Just tried it in Turbo Engine, and it plays wonderful.

I don't think Sonic 1's parallax is even possible on the Turbo.

It works in theory, that's it!

Did you try the demo? At the very least, horizontally scrolling Sonic-style parallax could probably be replicated very similar looking. The lack of vertical scrolling of the parallax would be a positive to me, since it looks ridiculous in the original Sonic in particular. This demo is a work in progress by a single person and the results are already very impressive.

Level 2 of Ninja Spirit.  This is pretty close to 'faking' 2 independent bg levels.  The far trees in the back vs the trees in the front move both horizontal and vertically in parallax to each other.  Something like that would work fine in Sonic.  Beside I think Sonic for NeoGeo Pocket has no parallax at all even.  :oops:
