I dont think it was released in ADF form, but whats the problem copying the executable onto an ADF image?

Those are good A500 demos by that group - including this one:

But I wonder ... how are they getting such crisp audio from the Amiga?  The audio tracks don't have the Paula 8-bit sound at all.

I don't have the executable. All I have is this youtube link. That's why I ask.

That's not running on an A500 though (it requires AGA and a 060 cpu is preferred)

That demo uses the old 14bit-audio trick, and it's actually playing a streaming adpcm-track instead of a traditional mod-file.

If you want more newly produced OCS demos, check these out:

http://www.pouet.net/prod.php?which=3880

I would also like to recommend this highly polished but somewhat unknown demo from 1995:

Ah!  I wondered about the 14-bit audio trick, but I didn't realise it was that crisp.  Also, I thought I heard stereo panning, which I didn't think was possible with the 14-bit audio trick.  Maybe it was mono, though.

So, was the PCM track composed at all on an Amiga?  I'm assuming with a PCM audio track, this demo does not fit on a single floppy!

4x 8bit channels => 2x 14bit channels - that's it I think.

With 14 bits you get 2 channels, so yes, it's in stereo :)

To be honest, I don't know what the track was composed on, I got it from Jazzcat as an mp3-file and converted that to adpcm. And no, the demo most certainly doesn't fit on a single floppy as it requires several megabytes of diskspace.

Oh, okay.  One more question: does this demo run on an unexpanded A500 (i.e. 68000 CPU)?  Because if it only requires several megabytes of diskspace then I assume it's unpacking the audio on the fly (rather than working from uncompressed PCM music - which would take dozens of Megabytes).  I'm just wondering how you accomplished that.

If you're talking about Metropolice, then no, it doesn't run on an unexpanded A500 (as I've already said, it needs AGA and preferrably an 060). Boogie Town on the other hand of course runs on an unexpanded A500 and fits on a floppy :)

Holy ****.  I never even knew this demo existed.  It's amazing.

Post by: nickoteen on December 19, 2012, 07:40:23 PM
Yeah, it IS amazing.
 
Can anyone (with sufficiant knowledge) PLEASE make an 880KB bootable ADF version ? I'd do it myself, but I don't know how.
 
I tried the 471 KB exe today from within WB 2.1 and ... nothing happened.
I got to "TITANICS decruncher decrunches while loading ..." part and ... nothing. For some 20 minutes or so. I tried to run it twice but it was a no go.
 
I only have 1 MB of ram so maybe that's why it wouldn't run (?)

It really need all the available memory it can get, but it works with 1MB.

I quickly made an adf-version, hope it works: http://britelite.infa.fi/boogietown.adf

It works ! The music is different though. It's like it's missing some parts of the tune which are clearly present in youtube video.  Youtube version sounds much ritcher. 1 MB of RAM, you think ?

Are you sure you have both channels connected? :) I'm pretty sure it's not a 1MB issue, because that's the machine it was made for and tested on. Haven't tested on KS2.x though, only 1.3 and 3.1.

Yeah, I managed to connect the audio leads to my 1084 in a totally wrong order. Only one channel was actually working. Yeayee me ! Now it sounds as it should, it sounds great.
