okay i guess, but i don't bother writing it, as it only works on ST and not on STe
Hard to appreciate if one's unfamiliar with the ST's limitations. But this demo is playing a Protracker module at 20 kHz in fullscreen, with four big VU's, 416 dots oscillo and some text chars in one vbl. It's a big feat. technically.

Paulo Simoes knows his job with ST hardcore tricks

Hi !

I do not know if it works on STE, because i don't have one, but it works on STeem 3.2 that is an STE emulator as well as on a STF.

Anyway, this screen was built in October 2004 as a challenge that i did to myself to do a fullscreen version of my MOD replay mixer.
On top of that, the program would have to use the biggest scope possible on ST low res (416 pixels wide in fullscreen).
This means that the replay frequency would have to be 416*50 = 20800 Hz.
To be able to do that you need to have 4 updates to the sound chip every 3 lines.
As every VBL you have 313 lines, if you have 4 updates every 3 lines, you get 313*4/3 = 417.333 .
In fact, you have a sound chip update every 384 cycles.
If you mix that with the precise needs to maintain the fullscreen, with 6 sync switches every 512 cycles, may be you will understand the coding mess this represents.

I included this to Sommarhack 2011 just for fun as this screen would have no chance to go anywhere.
There are no appealing effects to keep the viewer interest after 20 seconds, no great graphics, no big design to have a nice multipart changing demo.

Sorry, this is again only a tech screen with some good quality sound for STF and a piece of crazy coding.

This has always been the way i enjoyed the ST: try do build things that would seem impossible at first.


Bye,
Paulo.

impressive technical achievement. it sounds crystal clear and still has time for 416 dots and 4 giant VU's. All this in fullscreen !
Congrats, Paulo !

It *almost* works on my STe, nice clear sound, just a slightly jittery screen affecting the visuals. This would have kicked backsides back in the olden days.

Exactly what Zerkman said!
