I'm glad the Almost Real demo was released through the Futuredisk, it was really really worth the long wait Wink

In conclusion: they are the best MSX demos, but they DO NOT WORK on normal MSX1 computers. I did my own tests with the following computers: SONY HB-75, PHILIPS VG-8020 and TOSHIBA HX-10. "SCREEN 3" part runs fine, but in "SCREEN 2" part, part of the image is missing. Again, it works fine on my NMS-8245 and SVI-738.

Greetz!

Hello,

Yes they do. Not on yours it seems, but fine on the ones I've seen. We never used a SVI-738 for anything - the demos were coded with an SVI-728 with no VDP2 whatsoever involved. Some of the demos (Vesikauhu, Alankomaat & Merituuli at least) used a VDP copying trick that I discovered by myself and maybe SVI-728 was the only model it worked with that hasn't got the VDP2, who knows. Anyway, this trick was hardly of any use in the newer demos: it was mostly there to save my own coding time a bit. The demos should look quite ok without the trick implemented in the hardware and even identical if I could bother to fix this bit.

I feel some of the people in these forums are trying to argue in the lines that we actually were a bit faking all along: our demos weren't coded with or for an MSX1, the musics were ripped from Spectrum, what next? Anyhow, I think they are failing to recognize one crucial point: our demos were really really simple! Here's the basic formula for almost each and every effect:

1. Precalculate some nice slices of tiling animations with a PC.
2. Fill the video memory with the animations, thus creating an illusion of a fullscreen effect.
3. Move the characters for the width of one slice (takes 768 operations, cheap).
4. Update the new slice that emerges from the side of the screen (one slice could be for instance 32*192 pixels, once again a cheap operation).
5. Wait for half the frame you have left over. Smile

And that's all. We did this almost every time, sometimes for the name table and sometimes for the sprites, but always with the VDP1 since there's really little we would've done with anything more sophisticated. The effect would also suite fine any microcomputer whatsoever that has a character table you can alter. I think some people have actually done our effect in the past with different machines, only they never were arrogant enough to fake as massive animations as we did. Smile

Oh man. Feels good to get some feedback from the MSX community.

Making stunning effects is mostly about good ideas. Looking at the demo's of Bandwagon and Lieves!Tuore is an awesome experience. And - just as with Unknown Reality - as soon as you know what tricks were used, you notice the basic ideas were indeed fairly simple and quite often implemented in a much simpler way.

But isn't that what coding on a low-spec. machine like MSX1/MSX2 is all about? You have to be smart to get stunning effects out of it. Respect to all demo-makers out there! Smile

Yeah, Unknown Reality mostly consists of one effect too; updating the V9938 vertical scroll register (R#23) every line Smile

I've said it before but I'll say it again, I really like those demos from BW and LiT. Especially Avaakkus (great effects for a MSX 1, still trying to figure out the "howto" of the vectorball part), Aekrus and Rappio. Screen 3 rules ! Smile

BTW, AATNOS doesn't seem to work on my MSX, it says "not enough memory".

And what's the meaning of those demo names ???

nf - I know you and the rest of the Bandwagonists had reasons to drop MSX development.. but... since MSX exists 20 years now... pretty pretty pretty please??? Smile

Sorry for me being late about it, but Wink

LYRA-II was originally a ZX Spectrum demo by ESI (ethanol soft inc).

clicky

... and here are some more ;) for good measure ;)

Just wondering, is this LYRA-II demo (MSX version) available for download somewhere ?
