Title: 30 Years Megademo released!
Post by: MaV on 09:59, 25 June 16
It's been released, and it looks good!

30 Years Amstrad Megademo by benediction & Dirty Minds & Futurs :: pouët.net (http://www.pouet.net/prod.php?which=67656)

(https://www.youtube.com/watch?v=zhh1xZ6OXp8)

Personally, I like the parts of Shinra, Benediction, Futurs, and Vanity, though that's not set in concrete and might change.

Awesome job! Well done to ALL teams involved..
Better late than never!

Futur's part and Longshot's (did I see correctly?) for me look great. The menu is terrific!!

Another milestone in demoscene IMHO!!!

Must try on real machine though ASAP..

Wow, I got my name featured in a demo! :o Shame that the part was originally written in 2014 and hasn't been updated, and I'm no longer an active member of the CPC scene, but it still gives me a warm fuzzy feeling inside. :)

So far, I've only tested the demo on WinAPE, and for some reason, I can't view Futurs' and Vanity's parts, even when I set the CRTC to type 1. I don't know why the CRTC detection isn't working? I know there are problems with detecting CRTC 2 in WinAPE, but I didn't think CRTC 1 would be a problem. Fortunately my real CPC has a type 1 CRTC so I will try to test it tomorrow. There seemed to be problems with disc side detection on WinAPE, even when I used the double-sided DSK file.

Having watched all the parts on YouTube, I was most impressed with Benediction's 'Quest for Perfection', Futurs' and Vanity's parts. I was amazed to see four old demos running simultaneously in one screen! :D

Oh, seems to be 6128 exclusive. Schande ...

It's 128k, but CPC464 with expansion seems to work (emulated). Nice !

Uuhh! Super awesome! Our best demo makes succeeded! I'm at work and could only watch the GPA part. Just great!!! These totating year-number, and eveytime the effect gets better. Nearly like a time machine! Super!!!


Will watch more during my next break....

Winape should not properly emulate a CRTC1. If you want to properly watch the demo on an emulator, you have only two choices :
- cpcbox
- ace

Ensure to remove the fast disc emulation on winape ; we have not noticed issues on it (however I have modified some piece of code to hide a bug in winape fdc code)

I don't agree with modifying code to make it work on an emulator.

You already stated which emulators you say will run it correctly and others need to fix their emulation to make it work.

I have tested it on Arnold and seen a couple of problems which I will fix.
(CRTC1 not detected correctly, some distortion scrolling down on the main menu. These will be fixed and a new release of Arnold will run it much better :) ).

EDIT: Keep pushing us with great demos :)

A great team work demo with eclectic content! (saldy, the parts assembling are not polished)
As I love pixels, I mainly enjoy the animated splash screen, main menu and Vanity hidden part.
Shinra, Benediction, Futurs and Vanity parts are pretty good. Thank you for playing the game!!!  8)

This massive release deserves more comments, here am I for a few positive dedicated messages, Pouêt is not enough.
Dedicated messages means : see previous comments from others for global message or obvious comments.  :P


I'd like first to congratulate Krusty: despite time and rising issues (we know some of them), he did keep faith and will to achieve the goal.
Might be what is the most impressive to me in the whole story.


Impressive also: did you notice how much good is the part from Eliot? how much he improved since his last release?
Sounds good for his next release(s).


Futur's part is something very special to me. Hey! it's a one-screener as we used to have in the early years, but what a one-screener!
I do take this as a nice hommage to old one-screeners (... and overpass them btw).


Texts from GPA/T&J are also very nice for such a celebration (mega-)demo, well done!


---


All in one, you guys from 30YMD: thanks! be sure I find motivation in some of your work to go back on cpc code.  :-*

Title: Re: 30 Years Megademo released!
Post by: TotO on 15:11, 28 June 16
If I'm not wrong, the solution found to work around the problem was to check two times if the floppy disc was inserted.
So... the issue is not exactly known... But all work fine on a real CPC without this "emulator friendly code". (some peoples said to not do it)
Title: Re: 30 Years Megademo released!
Post by: TFM on 15:24, 28 June 16
Sounds like an issue with head load time. The FDC code in the 30 years CPC deme hopefully will see version 0.1. Because it all would fit on one 3.5" disc without changing discs. Just to provide an idea.  :)

yes, of course.

In the code where I test if we are with the right disc I call two times the following routine, instead of one.
When called one time on winape, the turndisc part is  systematically shown.


FDC_Scan   
ld a,%01001010     
call PUTFDC     
ld a,(FDCHEAD)     
sla a     
sla a     
ld b,a     
ld a,(FDCDRIVE)     
or b     
call PUTFDC     
call GETFDC     
ld (ST0),a     
call GETFDC     
ld (ST1),a     
call GETFDC     
ld (ST2),a     
;Lis information dans A.     
call GETFDC ;Numero Piste     
ld (.track_nb), a     
call GETFDC ;Tete logique     
ld (.side), a     
call GETFDC ;Nom Secteur     
ld (.sector), a     
call GETFDC ;Taille secteur     
ld (.size), a     
ret
.track_nb db 0
.side db 0
.sector db 0
.size db 0

which use the following routines from Arkos FDC routines probably modified by Syx

FDC_STATUS          EQU $FB7E ;
;Get data from FDC
;Ret = A=FDC data
GETFDC     
LD   BC,FDC_STATUS
GETFD2     
IN   A,(C)     
JP   P,GETFD2     
INC  C     
IN   A,(C)     
RET 




PUTFDC   
  EX   AF,AF'   
  LD   BC,FDC_STATUS PUTFD2     
  IN   A,(C)   
  JP   P,PUTFD2   
  EX   AF,AF' 
  INC  C   
  OUT  (C),A
    RET 


This issue may come illogical things in the FDC code before which is not problematic on a real computer, I have never tried to rad any doc on FDC and have not idea of how it works.

I added comments. Do you check ST0/ST1/ST2 in your code or assume all is ok?

Which Winape did you test with? Is it the newest?


EDIT: Code does a read id on side 1. Internal drive will ignore that because it's single sided. So this code works on both single sided and double sided discs allowing you to insert the disc you want.

So if a the 3" version is written to a double sided disk but only one side then the load will fail to find the part.

Not sure why Winape needs two id reads to make it work??
Title: Re: 30 Years Megademo released!
Post by: krusty_benediction on 21:07, 28 June 16
I develop on several (Linux...) machines, not sure the tested winape is always the same (high probability that it is version 2 beta 1) ; I cannot verify now.

I do not check ST0/ST1/ST2 at this moment ; only later after a call to load the sectors of a file (in fact it is Targhan's routine which do that by themselves)

And yes the code is voluntarily the same on 3" and 3"5 drives (thus you need the double sided dsk for emulators and to respect the order of the sides on 3"5 drive).
Title: Re: 30 Years Megademo released!
Post by: TFM on 21:13, 28 June 16
GETFDC and PUTFDC only check bit 7 (highest bit), so this is to check if the FDC is ready for data transfer. But the routines DO NOT check other bit of the main status register. That's bad! They should at least check bit 6 (data direction!). You can easily add that.  :)


Other issue: Do you check for Drive Ready before you read the ID? Well, maybe in WinApe you "switch on the motor" too late and this way the second "Read ID" only works. This is in case the real 3" drive reports "Ready" a bit before WinApe does it. OR: Your real CPC has a floppy with jumped Ready signal. Here: Read Status 3 before issue "Read ID" command, to be sure the Drive is Ready AND wait enough time to be sure the drives with Jumped-Ready Signal will be "Ready" in reality (and not only report so).  :)

Thank you guys for this, I never expected to see it finished :)


There is a lot to love about the quality of this megademo. The intro is really good, the scrolling in the menu amazing, the parts are really polished.
I like mostly the Shinra and Benediction parts but the others are cool too (new sprite record, GPA screen with big greet memories of old/new sceners and game companies).
I think the Futurs and Vanity must look amazing, I only checked the youtube for these parts, since I now have only CRTC 0 CPC and these parts should mostly look great and smooth in the real machine and you miss the magic in youtube or emulator. It's a pitty I only have a CRTC0 CPC and CPC+ here, I used to have 3 CRTC1 CPCs back in Greece.



Where there any other releases at ReSeT?

3 discs are used in order to be able to launch the demo on 3inches disc without having to create two versions of the demos.
Maybe it was a wrong choice if nobody use anymore the original drives (I do not myself)

It's always a good idea to go for 3", I mean it's 30" of CPC years.  :)  However, why not making a version for 3.5" (5.25" is the same anyway) in addition? It shouldn't be much effort imho.  :)  If I can help with FDC stuff let me know.  :)

I am not sure I am ready to spend more time on this project now, I need to do and think of other things.
ATM I have 0 bytes free (so almost impossible to fix future bugs that can be found), but if I remove the turndiscs I should have enough space for the extracode.

@TFM (http://www.cpcwiki.eu/forum/index.php?action=profile;u=179) I can suggest:
- to wait (and pray ?) that I am ready to do that
- to share you the code in order to let you modify what can be done (as everything is fully automated in a Docker container, maybe it is also necessary to write the tools able to manage discs with a different formatting that the AMSDOS one)

I've just discovered how to write  links with anchors in youtube videos at specific position.
So I have added them tothe 30 years megademo video in order to select quickly which part to watch. Here is the link https://www.youtube.com/watch?v=zhh1xZ6OXp8 (https://www.youtube.com/watch?v=zhh1xZ6OXp8).

Note that it is also possible on a real CPC to load only one specific part:
RUN"30YMD" 'BENEDICTION
RUN"30YMD" 'CREDITS
RUN"30YMD" 'DIRTY MINDS
RUN"30YMD" 'FUTURS
RUN"30YMD" 'GPA
RUN"30YMD" 'PULPO
RUN"30YMD" 'SHINRA

I like that they are announcing the awards at Revision on...


(If you don't get the joke, you're not really a demoscener... and you're not really missing a great joke! ^_^)

I have a VOB file; I can share it with you if you are able to create a better video; I'm not expert, I do not know how to do it differently.

BTW what is the interest in doing an HD video of a SD video ?

for the internet visibility... despite CPC not quite being even 480p, if you don't have at least a real 720p50hz or 1080p50hz you can't see the proper clean pixels on the Youtube Video and animation frames are not well adjusted.


But yeah I quite catch your argument or "just pulls it on a real machine"...  ;)


Still better to have demos properly displayed on youtube in clean HD than loosy 240p or alike full of blurry compression artefacts (exagerating, the 480p version is not that bad of course).

got to remember CPC being somewhat on the 272 or even 280 vertical size, it doesn't match well with a 480 vertical size (not clean magnification)

Also online watchers may have many different sort of screens to display so best quality from the beginning ensure best watch pleasure for the masses.
And many Demo-fans are not especially Amstrad CPC specialists and may not be wanting to fire proper emulator or have real hardware.

and in proper HD sizes you can see the proper pixelings as well and see if mode0 or mode1 or 2 ... and clean screens when video is put on pause.



exemple :

the "proper" Overflow's version in 1080p50 available :

some reposts in "low res" (and emulator displayed lol) :

another exemple : oh sweet 240p I meet you again...

if original video is in "lowrez" there is compression, so there are artefacts on the screen...


360p:

1080p50 :

of course it is not like as it should be watched : on a real CRT screen, but it doesn't give a good watching experience to have those compression artefacts, blurryness or even bad sound quality or bad re-scaling on modern HD/4K monitors.

just saying.
