Made an old-skool demo! - Page 9

Vortex · 14 November 2009, 09:16

Allow me to answer that question (I'm sure pmc won't mind)...

pmc finished his first part, and is conjuring up another one I think...

I've finished the Boot loader + loader part for the most part. Just have to add some small stuff. Also thinking about my main part...

Yes you've guessed it right.

This is not a Scoopex demo, it's a fucking megademo...

In percentage terms maybe 30%, maybe, at a total guess - not really sure - maybe less, maybe more.

In all seriousness it'll take some time before it's finished yet is the best way to put it. Sit tight though, we'll get there.

Awesome! I have patience looking forward to it :-) its cool we have the priveledge of new oldskool demos being created in 2009/10, im so excited :-D

Kitty · 16 November 2009, 01:09

Ok DemonHellraiser, I got Adobe CS4 , Adobe After Effects and the plugin Zaxwerks 3D Invigorator Pro

Only problem I got is I have never used after effects and the plugin is for after effects isn't it.
I had a look at after effects and it seems it some kind of 3d animation creator and not a design package like photoshop, am I right?
I was hoping I could use the plugin within photoshop but this seems not to be the case.
Any help on this would be great as this seems to be way over my photoshop skills

Maybe a new thread in off topic might be a good idea, so not to hijack this thread more than I have already

Sorry about the lateness with the track pmc, still having some problems with my miggy but I uploaded a few of my old tracks that I did on the Amiga back in the day, they are all mp3 format unfortunately but there are around 75 tunes of Amiga goodness or badness .. the tunes aren`t really that good but for those interested in some other Amiga tunes not heard before. www.amigamusic.info ;D Enjoy!

No worries man - to be honest I didn't think there was a delay - there's no rush, take your time. Any tunes you can make for us will be very much appreciated. In fact, if you're up for it we're looking for as many tunes as possible for the demo parts. I posted an ad on here asking for ProTracker dudes to get tracking but so far there's not been much interest. Zetro replied, gawd bless 'im

, so with you and him we've got two musicians.

Au contraire.

I thought there was some good stuff in there - much better than I could do no matter how hard I tried. Looking forward to your first track for the megademo!

Cheers matey! Yeah I am definitely up for writing as many tunes as possible, thanks for the comments too, it is a first time that I have put all the old Amiga tunes together in one place, used to be double the amount but unfortunately I don`t have the original data anymore.

Will keep you updated!

For pmc, 16 color iff in the zone

pmc · 19 November 2009, 08:03

@ Kitty - LOL!

Nice one - now I know what logo will be used as the title screen of any future Retro Megademo II!

DH · 20 November 2009, 19:35

Now this babe was a little harder to do.

I had to use Adobe Illustrator for the text so I could flip the last 'R' around 180 degrees. I know you'll all say, you can do that with Zaxwerks, but and it's a big but, the lighting goes in reverse with the last letter, so for that the lighting on the 'RT' is lower front but the flipped 'R' is lower back

Anyway, I eventually found out how to correctly save each letter in .ai, loaded each one in and spaced them correctly, added the colour and finally the lighting effect, which is now correct

32 colour

pmc · 20 November 2009, 20:36

Skillful graphical manipulations DH.

Sorry to stray off-topic from the talk of the new demo, but I've just been testing out cross-assembly on the PC using vasm, and I must admit, it's pretty amazing. I have no doubt that this is how I will be assembling programs from now on. It's so quick, and I'm able to use editor's I'm comfortable with (Notepad++).

Anyway, as a test I tried assembling "WeAreRetro" using the following command line:

Code:

	vasm68k -m68000 -Fhunkexe -o weareretro -nosym weareretro.txt

It gave me an Amiga executable in less than a second (love it!), so I immediately tried it in WinUAE using a standard A500 Quickstart setting. Unfortunately it almost immediately guru's after the demo starts. Setting the CPU to 68020 however works fine.

Looking at the source, I saw the assembler option "opt p=68020" being used. I changed it to "opt p=68000" and tried to recompile, but was greeted with the error:

Code:

	error 1 in line 526 of "weareretro.txt": illegal operand types

Line 526 is:

Code:

	.get_vbr_code:	movec	vbr,d0

According to a post by Codetapper ( http://eab.abime.net/showpost.php?p=360105 ), that's a 68020+ instruction. He suggested a replacement in his post, so I did just that. I changed line 526 to read:

Code:

	.get_vbr_code:	dc.l $4e7a0801

Assembled and it works. I just thought I'd bring it up

I wish the -m68000 parameter would have thrown a warning so I could have seen the problem immediately. Not even the -devpac parameter helped in that respect. Oh well, can't win them all.

pmc · 24 November 2009, 12:55

@ Jason. Cheers for checking out the code guy.

The behaviour you're seeing while assembling is as it should be and the reasons for it are correct and the 68000 workaround (poking the movec opcode to memory) was too.

I'm surprised that the -devpac assembly option didn't work - maybe that's correct behaviour (I've never used VASM...) but if PHX (the author of VASM) is reading this thread he'll have the definitive answer as to whether this is right or not.

I agree..the one without the larger "T" is my favorite too!

Ok, the error message could be better. In fact it should be something like "instruction not supported on selected cpu".

Unbelievable. This is the same 68020 movec instruction as before, just in hex-code. And this works?

That's the expected behaviour, because the OPT p=68020 directive in the source text takes priority.

AFAIK Devpac has no command line option to select the CPU, so the vasm-behaviour from above applies.

Why shouldn't it work? It's never executed on 68000 machines, code checks the CPU. I'm pretty sure it wasn't the cause of the crash when the code was assembled in 68020 mode.

Well, you never actually get there when running 68000. If you remove the processor check or just jump to that part of the code on 68000 I'm pretty sure Amiga goes KABOOM!.
