The Longscreen was coded in 1988 by Sunnyboy and it featured graphics
by Nexus 6. This screen scrolls a lot of screens in one vertical
blank while loading the graphics from disk with an interrupt loading
routine. These disk-routines are the origin of the fastest copy-program
for the ST, the Turbo-Booster.
Nexus 6 / X-Troll has just managed to image the original data disk of
the "Longscreen" demo in a version from 1989. Cyclone / X-Troll added
the necessary program disk and reworked the sources a bit. The demo
should run on machines with 512k or more and TOS 1.0 to 1.62. Don't try
with TOS 2.0x since it crashes on a Gemdos call.
Running on real Hardware
I am not sure if the Longscreen will run from a disk which wasn't
produced in the original way. MSA loses some tiny but important details
about the structure of the Longscreen data disc. So I simply can't
guarantee it will work after being written back to a real floppy.
However we are working on a solution for this problem. In the meantime
enjoy the screen with either SainT or STEem.
Running with SainT
The demo runs flawlessly on SainT 1.70b if you use the following
- Drive Speed: Realtime
- Emu. Speed: ST 8 MHz
- Enable Sound: Disk Drive
Insert LongScr1.MSA and wait until the demo demands disk 2, then
enter the disk menu via F12 and insert LongScr2.MSA into drive A: Make
sure you DON'T RESET SainT just press RUN again and follow the
instructions on the screen.
Running with STEem
First we thought the demo wouldn't run properly
with STEem because it's loading way too fast. But as Grazey / P.H.F.
pointed out, STEem has a well hidden setting to activate accurate disk
timings. You need to set the following options. Click onto the little
wrench symbol on top of the STEem window. you should see the following
Go to the category "General" and uncheck the box "Automatic fast
forward on disk access".
We are not yet done. Click onto the little disk icon at the far right
side of the STEem window. You should see the following window:
Click onto the small disc icon with the wrench and activate the
setting "Accurate Disk Access Times (Slow)". The change was successful
when you see the same red snails appear in front of both disk drives,
like in the above screenshot.
Insert disk 1 in drive B and disk 2 into drive A and start STEem.
Doubleclick "LONGSCRN.PRG". You should be able to watch the Longscreen
