Short: Picasso96 system for Amiga graphics boards
Author: Tobias Abt <tabt@studbox.uni-stuttgart.de>
Uploader: Tobias Abt <tabt@studbox.uni-stuttgart.de>
Version: 1.11
Type: gfx/board
This archive contains all you need to get Picasso96 up and running on your
Amiga. Picasso96 offers support for many different Amiga graphics boards,
has builtin HiColor and TrueColor support for intuition screens and many
more...
Requirements:
- Kickstart and Workbench 3.1 (V40),
- Motorola MC68020 processor or better,
- CyberVision 64, Domino, Merlin, oMniBus, Picasso II, Picasso II+,
Picasso IV, Piccolo, Piccolo SD64 or Spectrum.
AnyWare, i.e. not commercial or ShareWare. No distribution restrictions.
Short history:
Changes in 1.11:
- fixed severe bug in SetRast(),
- undocumented BltMaskBitMapRastPort() feature implemented, JEyes now
works as expected on chunky screens,
- added first version of fastlayers.library which improves window
handling performance,
- added color expansion for ZorroII PicassoIV's, speeds up e.g. Text()
significantly,
- fixed wide fills with Cirrus GD542x in TrueColor,
- CyberGraphX emulation: DoCDrawMethodTagList() message fixed to work
as expected and not as documented in CyberGraphX autodocs...
Changes in 1.10:
- fixed bug causing scrambled displays when a chunky screen with less
than 256 colors was removed from the card,
- removed bugs that prevented e.g. CyberGrab to function with HiColor
screens, there are still some problems left,
- fixed software mouse sprite trashing on Picasso96API screens,
- hardware clocks and other restrictions checked better now,
- included workaround for stupid programs who think they'll get a planar
one plane BitMap if they pass in a chunky bitmap as friend_bitmap to
AllocBitMap(). Even more, they set the BMF_DISPLAYABLE, too. Those
programmers obviously did never read the autodocs. Sometimes I could
really get mad... This includes programs like WordWorth, TrapFaxView
and others. This workaround prevents those bugs but it is still not
the way we would like it... In other words, I strongly discourage such
incorrect use of system functions...
1.9:
- skipped due to error uploading a version 1.9 which was actually 1.8
to Aminet...
Changes in 1.8:
- transparent blits improved:
- WWW browsers render images correctly,
- NewIcons work better,
- transparent chunky2chunky blit speed increased,
- ObtainBestPen patched to overcome problem with ECS Amigas,
- add new monitor tooltypes:
- "NoPlanar2ChunkyBlits=Yes" uses CPU conversion routine, might be
faster on high-powered Amigas,
- "NoBlitter=Yes" will disable the blitter entirely, only useful for
debugging purposes.
- DisplayInfo values for RedBits etc. now correct for each mode,
- potential division by zero problem in CyberGraphX emulation fixed,
- ShapeShifter driver works better, memoryless screen bug fixed,
- fixed screen open bug causing scrambled display on other screens on
the Cirrus 542x based boards,
- handling of hardware sprite on interlace screens improved for Cirrus
boards, Cirrus chips seem to have a problem with hardware sprites on
doublescan modes, though.
- Merlin blit bug removed,
- SD64 improved, but still alpha.
Changes in 1.7:
- Nasty bug in memory allocation fixed, big screens open again...
- PicassoII interlace mouse pointer,
- scroll down using mask should work as expected on the Merlin, now,
- Merlin sprite position bugs fixed,
- some CyberVision driver bugs fixed,
- Installer script enhanced, gives more warnings at startup,
- defective 3.0 support removed,
- PicassoIV template blits finally correct...
- small hack tool for PicassoIV FlickerFixer display refresh rates
Changes in 1.6:
- Merlin finds modes again (stupid cut'n'paste bug...),
- Merlin panning fixed,
- planar modes work again,
- mouse sprite in planar modes shows up again,
- screen bitmaps enter board immediately when allocated, this results in
faster opening screens,
- internal handling of bitmaps simplified, which will lead to even more
flexibility,
- workaround for Workbench "Show by Name" problem in Hi- and TrueColor,
not entirely perfect, though,
- soft sprite smearing on Village and Picasso96API screens fixed,
- changed minimal accepted KickStart version to 3.0. If it works for you,
please tell me!
Changes in 1.5:
- BltMaskBitMapRastPort() in Hi- and TrueColor works now,
- mouse sprite should be correct now,
- CyberVision 64 driver should work a bit better,
- Spectrum memory size recognition should work,
- Cirrus 542x sprite offset problem in HiColor should be fixed,
- Picasso96API enhanced,
- support for vilintuisup.library enhanced,
- maybe even more... :-)
