Recommend Some Demos

Recommended Posts

I recently built my SIO2PC USB cable, and am reliably loading software from PC now. With that done, I'd like to run some demos. I'm running an Atari 400 upgraded to 48k RAM. Any suggestions for something cool that will run on this configuration?

NTSC or PAL?

I enjoy all the Silly Pack Demo's.

NUMEN

 

Edit: Oops, 400 with 48kB. That won't work.

yea I didnt find a lot of demos that would run on my 48k NTSC 400, there were a handful of text scroller's and graphics routines but not full blown demos

 

Plenty of games work with it, I actually liked the machine quite well... but I ended up selling it and getting a PAL 65XE to doctor up (which I am still sloooooooowly doing)

I'll probably get an XL or XE eventually, but I went with the 400 first among the Atari 8-bit line out of nostalgia. Simple demos are fine, I just like seeing what I can make the hardware do.

I grabbed the disk pack off archive.org and just saw what would and would not run, it was fun cause somethings would start then crash in a blaze of glory on the next effect

Is there an NTSC version of NUMEN anyway?

I have tried to find an NTSC version of NUMEN, but no luck. However, NUMEN will work on an NTSC Atari if the NTSC GTIA is replaced with a PAL GTIA.

 

This version of NUMEN works on my iPhone. :)

Thanks everyone. This should be a fun collection of demos to try out. I also came across the 1K matrix demo. While it's a single effect, it's a pretty neat one for having crammed it all into 1k.

So, it's only a software check of $D014? Or, is there more to it?

 

Why couldn't this be easily patched out in software if it will run on an NTSC ANTIC? Would the GTIA really matter? I don't see why. Maybe some slight differences, but so what? Let it at least TRY to run.

Pal has more cpu cycles in VBlank period compared to

NTSC (50 Frames per Second > 60 Frames per Second) so ppl like me Max out code wise to do as much as possible in that given time. Ergo cutting off 1/10 of cpu cycles cuts in code....

most non 50 fps effects could be working around as they rely on CPU power and not actually VBL time. So double or triple buffering. Thats why some fx of Numen work... some I doubt. (E.g. the vectors in the end)

After watching many new demos with 3D effects, gouraud shading effects, morphing effects, fractal effects and whatnot, its is always nice to view some old (very old) demos that simply show what your Atari can do (programmed directly on the A8, not with an emulator or a PC cross-compiler, etc.). Simple fx, like showing 256 colours or 16 greyscales, simple animation fx, simple light/neon-light fx, etc. One of these old demos I like is "Discape" by Anthony Ramos, a multi-part demo programmed in Atari Basic with some ML subroutines on an Atari 800 between 1984 and 1985... http://a8.fandal.cz/detail.php?files_id=3518

 

What I find absolutely boring are demos that show several ripped pictures (e.g. from A8 games), play some ripped sounds/music (from an A8 game) and have a scroller (blablabla) anywhere on the screen. Alas, many german A8 demos did this in the 80s (and even in the 90s)...

Well... its a natural progression... we had those "simple" 80s style, then those 90s with Chunky 4x4 mode9 style, 00s started those "theme" like demos and now we are more into Amiga world...

 

What made me really "wow" again when connecting and testing my demos on a 1084s and those 50 FPS effects kick out. nothing can compare 50 FPS fx on a CRT... forget TFT... that's why esp. C64 guys still stick to 50 FPS effects as much as possible.

 

I tried that with the latest VBXE demo... the Chaos Zoomer was optimised to run in 50 FPS, the Plasma in the end and the Amiga Balls...
