Manual:
Another set of pathetic Aga monitor drivers, for the purpose of less flickering,
made on an A1200 with a Microvitec 1438.
Some modes may not work with 7 or 8bit screen depths, but any way it's useless
to select high depths with high scan rates. Although it may be that some lower
resolutions of a mode allow higher depths.
Since the drivers were tweaked for just one screenmode and resolution per main
type, the low res resolutions I did not test completely. Some or all may work.
The new modes and resolutions are:
DBLNTSC : 640×480 interlaced 120Hz/32KHz 307.200 pixels
DBLPAL : 704×528 interlaced 104Hz/30KHz 371.712 pixels
Euro72 : 640×480 not laced 63Hz/32KHz 307.200 pixels
Super72 : 800×600 interlaced 84Hz/27KHz 480.000 pixels
Multiscan : 512×384 not laced 90Hz/38KHz 196.608 pixels
---------------
*Installation:*
-Install Newmode or Modepro: Some Modes combined with some program need to be
corrected or enforced via mode promotion.
I.e., some programs may require a permanent promotion entry, in order to get it
right, some programs may need a single promotion procedure, some programs
may work via their standard screenmode settings. Overall, those few promotion
entries that may be required, they won't hurt.
-Make backups of your old drivers and everything else you want to protect.
-Copy the driver files to sys:devs/monitors.
-Make sure "VGAonly" is in there already.
-remove any directory in the "monitors" directory.
-Install a "standard miprefs call" into your user-startup. See miprefs readme for
that. Miprefs then will read all tooltypes from any driver at booting, and set
them, thus overriding the program "overscan".
-"Overscan" is a weenie, and does not understand. Don't fiddle with it, leave
the old overscan settings untouched. Miprefs will do the job now.
If you feel like, pray that I or you did not forget something. But honestly,
praying never worked and never will, and also I don't see much of a risk at
trying these drivers. Now either reboot, or just click all drivers first and
then the miprefs icon. Make sure the mode promotion will catch any new screen.
Now...Booom, Fssszzz-AAAAaaaagghh.... ;)

Tip: With stale AGA always use "Fblit", "Ftext" and "Blazewcp".
"Fscreen" is also worth a try.
