Short: Picasso96 system for Amiga graphics boards Author: Tobias Abt and Alexander Kneer Uploader: Tobias Abt Type: gfx/board Version: 1.40 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 3.0 (V39), - Motorola MC68020 processor or better, - CyberVision64, CyberVision64/3D, Domino, Merlin, oMniBus, PicassoII, PicassoII+, PicassoIV, Piccolo, Piccolo SD64, Pixel64, Retina BLT Z3, Spectrum or uaegfx (for UAE, the UNIX/unusable/usable Amiga Emulator). NEW! Picasso96 is ShareWare. Requested fee US$20 or DM30, free to use for PicassoIV and Pixel64 users (the manufacturers of those cards already paid for these licences) and the really few ones that already have sent us a donation. No distribution restrictions as long as the the archive is complete and none of the files within is changed. BBS notes may be added. Short history: Changes in 1.40: - fixed bug in rtg.library which could cause Enforcer hits during boot - fixed bug in rtg.library and PicassoIV.chip which caused crashes if a PicassoIV with 7.4 ROM was used without p4specials.library - fixed bug that caused screens sometimes to be black - new tags for mode id query functions for video output support - install script changed for ease of installation: - detects PicassoII's in segmented mode and issues a warning - new AttachSettings tool for basic settings file maintenance making things easier for first time Picasso96 users - Picasso96 is now ShareWare for users who don't own PicassoIV or Pixel64 boards and the installer script gives a hint about that - CVision3D: driver now working in ZorroII based Amigas as well - new environment variable "Picasso96/ShowModes": - "all": show all possible modes (including multiple modes of the same depth that are only different in their RGB format) - "essential": (default) the same behaviour as before, show only modes that are really different from each other - user supplied mask of RGB formats: decimal, hex($) or binary(%) value, see includes section about color formats; example: $e=%1110=14 allows only 24 bit true color and chunky modes Changes in 1.39: - implemented CPU function for planar BltPattern() with rp->AreaPtrn (still no support for bltmask and rp->AreaPtrn together) - fixed bug that caused enforcer hits with planar bitmaps in fast memory - remove some stupid mask considerations for Hi/TrueColor bitmaps (which caused problems on such screens using less than 256 colors) - Picasso96Mode has some extra features now: - corrected algorithm to look for unused DisplayIDs when cloning settings - new menue entry "Setting/Batch change IDs" which is used to renumber all of the DisplayIDs for the current settings - menu entry "Mode/Print mode" now prints mode lines for NetBSD 1.3, too Changes in 1.38: - fixed a dangerous bug in the clipping code (hi-words of some data registers were trashed) - implemented blitter emulation routines for planar bitmaps in fast memory except for: BltPattern() with rp->AreaPtrn as well as Flood() and Area#?() calls with rp->TmpRas->RasPtr pointing to fast memory; QBlit functionality is also missing for all bitmaps in fast memory - corrected BltBitMap() behavior to be same on all boards when blitting from bitmaps with less planes than the destination bitmaps has - new monitor tooltype "GrantDirectAccess": use this if you have problems with programs that use direct display memory access without using locking mechanisms like ShapeShifter on ZorroII Amigas with PicassoIV or with any Amiga using a CyberVision64 board; this tooltype when set to "yes" prevents bitmaps with different byte swapping requirements to be on the board simultaneously if they cannot be accessed at the same time without reconfiguring the board; when using PIP applications on ZorroII PicassoIV this tool type should be set to "no" (default) to allow all combinations of screen and PIP color formats - fixed a small bug that was possibly causing wrong colors with CLUT screens - PicassoIV: PIP handling (bandwidth calculations) improved, PIP windows on TrueColor screens are back, now switched off when window is occluded - Merlin: fixed a bug in blitter accelerated BltPattern causing enforcer hits in some cases - Merlin: planar to chunky blits wait for blitter ready flag between planes - Retina BLT Z3: minimum memory clock is now 55 MHz - CyberVision64: sprite colors are now set correctly when the mode changes Changes in 1.37: - removed SwapBitsRastPortClipRect bug (aka FastLayers/PictureManager bug) - removed bug causing crashes with PMTNG while editing the test screen - cybergraphics.library emulation now v41 compatible - included an emulation of the cgxvideo.library using the video overlay of the PicassoIV (not tested well, no CV64/3D overlay support yet, will not work with Isis because of tests for emulation) - added new board tool type "MemoryClock" which sets the memory clock (in MHz) of the board within the allowed ranges (you can check with CheckBoards to see the effectively used clock value). Boards that support variable memory clocks and the supported ranges (exceeding values will be clipped): - CyberVision64: 54-65 - CyberVision3D: 55-65 - Retina BLT Z3: 60-85 Note: Cirrus based boards already run at maximum speed and therefore do not support this tool type, Tseng based boards do not support variable memory clocks - PicassoII: added support for Pablo (all modes with 15 kHz and 50/60 Hz switch on the video encoder) and possibly fixed a bug with wrong colors - Retina BLT Z3: fixed a bug causing some blitter trash on 68030 based Amigas - extended PIP-API: - CLUT PIPs on Hi/TrueColor screens can have their own color table - PIP does no longer have to use the complete window interior
