This demo causes me headaches, I can run it both from adf and through WHDLoad but I find theres always some kind of graphic glitch no matter what amount of configs I try for this (including quickstart configs)

Has anyone got this to run almost perfectly or 100% perfect, I would be interested to know, and if so what config did you use.

Grab the file from here : http://www.pouet.net/prod.php?which=1650
Choose the A500 most common quickstart and put the file in DF0 (yes, put the file in the floppy drive DF0 Choose 'All files' in the open dialog). Start the emulation and enjoy the show

With just a few exceptions, all OCS demos work in WinUAE - the most common reasons why something gurus or fails is 1) requires kick 1.2 - or even an A1000 - these demos from 86/87/88 usually hate slowmem expansions, 2) kick 1.3 is ok but still hates slowmem, and 3) too little low chipmem free, adding chipmem won't help. For this last one, remove DF1/2/3 to save ram, might even require setting the CLI to one bitplane. Running them from harddisk will also use low chipmem, if you have no slowmem or fastmem - so yes, running everything from DF0 is recommended.

Warlock's ADF archive have lots of disks already set up with the requirements for the demos, and usually work fine with kick 1.3, no slowmem - so just pop them in DF0 and add slowmem if it fails (or asks for it!)


Using these tips will reduce "demo doesn't run" headaches to the point where it's not a problem anymore.

Actually I didnt even think to use a lower kickstart
I always stick to 1.3 usually

Best version yet, works great, question though what type of file is this, it has no extension like adf's have, ie .adf, very strange.

Er... the demo runs fine with 1.3

Well, at least most OCS demos work with kick 1.3, and I'm sure Coma does. Running an executable demo "in DF0" in WinUAE (as suggested) usually works - unless the demo expects *exclusively* what was regarded as "the normal Amiga" in 1988-1991.

Only a few early games and demos require kick 1.2 (or Amiga 1000, even fewer and earlier). Usually it's assumption made when loading tracks for these ones.


Most coders only had their own machine then, and couldn't test on other setups before releasing.

Usual rules:

-for really old stuff is: "music playing but crap or nothing on screen" or just "crap or nothing onscreen" = remove all fast/slowmem.
-old stuff+Guru or doesn't load tracks, go kick 1.2.
-demo exits to command line without starting: add 512k slowmem.



On Bitworld there is usually a link from each demo to the packdisks it was spread to the world on. The packdisks were usually made to at least allow to turn drives off, and sometimes freed some memory to make sure their release (of the release :P) would run.

None of these rules are perfect, but if one wants to really REALLY see the demo, one has to adapt the rig to what the coder had, at least sometimes...

[TCD]

Yep, agree with you on the approach how to get old OCS stuff running Photon Just wonder if Kittys version is somehow broken if it doesn't work properly.

[Kitty]

I think you may have misunderstood me, The coma demo file you posted works great with Kick 1.3 , I was just curious as to what type of file it is as it has no extention.

It's an Amiga binary ('exe' if you want). WinUAE just runs it when it's in DF0

it's my ringtone and that kickass
