Stock 1200 is tested, since I dont have a blizzard I didnt know how to test it but.. however what kind of problems do you get with this accellerator? Does the demo at least start?
The demo starts just fine, but graphics get garbled when the black & white picture should appear. My guess from the looks is that the external memory causes the problem and graphics end up to fast memory instead of chip memory.
mmmh.... the image is stored statically here

as you can see I put the CHIP modifier in front of the variable to force the image to be stored in chip ram, so it's correct, probably the problem is elsewhere even because it works on a600 with 2mb of pcmcia fast ram - isokadded on the 2021-09-15 12:55:37

Nice demo! Works fine in a stock A1200, but noticed that it dislikes Blizzard 1230 accelerator.

Good mood and celebratory! And technically rather interesting, as it runs on a hardware screen and yet loads from AmigaDOS. Also it doesn't seem to be written in plain Asm, but is smooth nevertheless. Would like to thumb it up for motivational reasons, but cannot, as it doesn't seem to be running on a plain A500. Watched it from an A600.
It's mixed ASM and C but mostly bebbo's GCC (with Ace framwork).
This demo, even if it's inteded for A600 should work on any Classic Amiga anyway, the only problem I got with very old Amigas is that ACE owns the blitter very early and in Kickstarts < 2.0 there is this strange behaviour to use the blitter do get data from floppy disk.
This a problem on the ACE framework, so it's not related to my demo.
If you just copy the whole floppy disk on an hard disk directory it should work even on your A500 (but of course you must have an HD).
Another option would be to use a ks 2.x on your A500.
I think on my 500+ works fine (dont remember).
Hope it helps - isokadded on the 2021-09-10 07:21:00

Even if there is only one main scene, it is interesting.
It needs 1 meg of chip. Probably it can be change to 512kb of chip
Anyway thanks to have published the source and thumb up of course :-)
The whole project started because I wanted to test performances for opengl on a vampire card + rtg, the goal was to calculate all the points real time.
The next challenge was to do to do the same thing on stock amigas but soon I realized there is no way to calculate all points at decent framerate so i started using the simples flowers and cut down the points to 360 for each frame.
Even with this limitations my stock amigas was not able to calculate each of the 360 pont so I started precalculating.
Precalculating means to put in an array all 360 points, each point is expressed in cartesian coordinates. In my first release I used 2 bytes for X and Y positions , so it is 4 bytes for each point and the final result must be multiplied for 360 because the flowers are rotating 1 degree at time (from 0 to 359).
At the end I used deltas, describing a point in relation to the previous one and I compressed the result using an algorithm compression called Huffman.
In my source code you'll find a huffman decompression routine that uses a portion of time every frame to decompress a chunk of data.
With this method I managed to stay under the meg of chip otherwise I would need some fast ram.
Probably you demoscene gurus knows better tricks to compress data, that was my solution, hope to get better in future releases. - isokadded on the 2020-08-02 16:05:24

errr what, no group nor credits on this one?
need come back for thumb once those get fixed --> biggie for now.
no group because there is actually no group, the demo is 100% coded by a single person (me) and I didnt belong to any group (and I've never) , even if I would really like to find a group willing to accept me.
