• Thanks Leonard !
  You can now try a 3D STNICCC 2000 like STF demo but WITH digi-sound ! :)

• Hi britelite !
  
  The problem is not the emulator.
  In fact your code does not set the image refresh rate (50/60Hz).
  So if you start your machine in NTSC/60 Hz as Steem does, you will get this small bug.
  You can check that on a real ST as well.
  This also means that you have plenty of CPU time left and that all screen can run at 60 Hz except that twister. Probably in some cases, when you are updating the frame buffer, your screen base address switch that is probably located at the VBL has already occured and so you are clearing at the wrong address ...
  There is also a minor graphic bug on the first girl screen pic: 2 small blue lines at the top.
  But don't worry these are details.
  
  Again, congratulations.

• Nice effects !
  A pity we get an sudden end.
  Also there is a little bug with the greetings twister: some data that should be erased is not when moving up ...

• Just forgot to add that that i still have time on the STE code path so you could have 2x176 dots instead of 2x144 dots but there is no physical pixel space without overlapping both stereo scopes or having more than 1 dot sometimes for some of the horizontal pixels and that would not look nice.
  I guess sometime you have to leave some unused CPU time ... :)

• demo Atari ST The overscan demos by Paulo Simoes [web]
• Actually, my first ever demo on the ST is from 08/02/1989 and is a small multipart demo called The Spectrum 512 Scrollshow.
  That program is refered by Manikin in Maggie 02 disk while reviewing the Overscan Demos release.
  I have never produced a disk image of it as it uses a very special disk format as the original Overscan Demos did and it also uses a costum way to remove the top border and so i am not sure it even works with current emulators.
  Who knows, if one day i have time i will do the code updates required to handle 11 512 bytes sectors on the first side instead of 5 times 1024 bytes + one time 512 bytes that is a much safer format.

• Hi !
  
  This is only a small tech screen to show the possibilities of Hextracker.
  Not much free area for graphics but some specific STF / STE graphics could have been included for the scope part.
  Now, you can costumize the colors by hacking the .TOS program file:
  - at offset $0E70 you can change the Scope beam color;
  - at offsets $105A/5E/62/66/6A/6E/72/76/7A/7E/82/86, you can change the 12 individual V.U. colors;
  
  Color format is $0RGB with R, G and B from 0 to 7 for STF and 0 to F for STE.
  
  Enjoy,
  Paulo.

• This is just for those who still do not know about this demo and MOD player allowing Protracker MOD replay at 50KHz for most of the MODs on a simple Atari STF with 1MB.
  The player can be found by not booting the disk.
  Enjoy it.

• Rulez for the time it was done: this product was released by me in 1990:
  the 14/05/1990 to be exact as it appears in the scroller. If you don't belive me, check the edition 2 of Maggie. An STE left border updated version was released the 25/07/2004.
  In 1990, there was not much like this.
  Use real HW, last SainT or last STEem.
