Short: Picasso96 system for Amiga graphics boards Author: Tobias Abt Uploader: Tobias Abt Type: gfx/board Version: 1.35 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. AnyWare, i.e. not commercial or ShareWare. No distribution restrictions. Short history: Changes in 1.35: - Implemented private semaphore mechanism which renders permanent priority patching obsolete - planar modes no longer share the display id with chunky modes, they get their own ids now - Retina BLT Z3: more blitting functions, friend bitmaps are now on board if possible, BltTemplate() acceleration (Text() should be much faster now), eliminated problems with wrong mouse sprite colors and interlaced modes - Merlin: implemented blitter acceleration for BltPattern() cases with monochrome patterns (8/15/16/32bit) - WritePixel() sped up to some degree - Software pointer sprite problems fixed within WritePixelArray8(), WritePixelLine8() and WriteChunkyPixels(), which showed up with ADoom. - OpenScreen() with depth=0 now behaves like CGfx, so patches for PhotoGenics are no longer needed - Cirrus GD5434 and GD5446 based boards: fine horizontal timing adjustments fixed Changes in 1.34a: - fixed bugs in PicassoIV.card - NCR77C32BLT.chip: - sprite colors corrected in 15bit - now pixel aligned panning only - default settings files now contain 32bit modes, too (needed for TrueColor on CyberVision* cards) Changes in 1.34: - optimized WritePixelArray() and the like (significant speed-up) - BltPattern() with color patterns fixed (TurboPrint6-GrafikPublisher bug) - BltMaskBitMapRastPort() is fast and flicker-less now - ScrollVPort() sprite position problems corrected (Myst) - CVision3D driver partially supports BltTemplate() acceleration (Text() should be much faster now), maybe some ZorroII problems are resolved now, too (unfortunately untested) Changes in 1.33: - fixed handling of panning that was broken when introducing the ScrollVPort() patch (Visage center option works again now) - PicassoIV: corrected flickerfixer setup, PIP fixes (menus are always visible now, max. zoom factor is now 8) - Blitting from Y4U2V2 bitmaps to Hi- and TrueColor bitmaps implemented. Changes in 1.32: - emulation libraries and Picasso96API.library now prefer faster cards for BestModeID type functions if more than one is installed - ScrollVPort() implemented and tested (thanks to James Ceraldi). This should fix problems with CyberAnim, too. - mask blits using same source and destination format (both bitmaps located in graphics card mem) are done with blitter if available - PicassoIV: new pixel clock for PabloIV PAL support added - WaitBOVP() and WaitTOF() added again after minor fixes, these were left out accidentally in the 1.31 release - drivers for the CirrusGD542X boards have been fixed. These were unfortunately partially defective in the 1.31 release. Changes in 1.31: - CyberVision64: 2MB memory detection corrected. - CyberVision64/3D: switching logic of scan doubler module fixed and tested. - Merlin: fixed bug in IRQ handler causing enforcer hits in some cases. - PicassoII: hardware IRQ only with PII+ fix. - Retina BLT Z3: - init code fixed (card locked up sometimes). - allowed resolutions corrected. - inversion and fill operations use the blitter now (in many cases). - fixed some details and added more zero pointer checks in WaitTOF() and WaitBOVP(). - DIPF_IS_DBUFFER set on all P96 modes to reflect implemented double buffering. - System2ScreenBlits tooltype added to explicitly allow expansion blits through host cpu accesses. This may speed up Text(), BltTemplate() and p2c blits but should not be used on systems where bus timeouts occure too early (FastGary option and some ZorroII implementations). If you experience ragged text output and lockups on Cirrus based cards you should not use this option. - fastlayers.library: fixed a bug with BACKDROP windows. - Picasso96Mode: "memory freed twice" alert and settings merging fixed. - added french translation to the installer script (thanks to Cédric Quillevere). Changes in 1.30: - Retina BLT Z3: - hardware VBlank interrupt supported. - corrected and checked all possible clocks. - hardware sprite works in HiColor now. - border problem reduced to one line at the top of the display in chunky modes. - memory check for 4MB detection (hopefully) corrected. - corrected a bug when blitting from ARGB to RGBA bitmaps (thanks to Stefan Sommerfeld for reporting this bug). - implemented WaitTOF() and corrected WaitBOVP(), both functions use the hardware interrupt now when available. - PicassoIV interrupt handling corrected to allow correct 16bit 44kHz playback with the Concierto sound module during VBlank activity. - new install script introducing update and uninstallation features. - Pixel64 and UAE drivers included in distribution and installation. - corrected double buffer handling of non-visible screens which used to consume all free CPU time. Changes in 1.29: - added Retina BLT Z3: - first alpha release! - hardware sprite in Hi/TrueColor not available yet - only scrolling is currently accelerated - DPMS should already work - chunky screens have one line of border at the top and at the bottom, this seems to be a bug of the NCR - most pixel clocks untested, do not wonder if the display is not stable in certain modes - no support for external monitor switches yet - only tested with 1MB, memory check routine might fail for 4MB boards. - added CyberVision64/3D: - first alpha release! - BltTemplate()/Text() and Planar2Chunky are not accelerated yet - DPMS should already work - ZorroII completely untested and might not work at all!!! - monitor switch could not be tested/implemented yet - on a ZorroIII Amiga it runs fairly well right now... - success and bug reports for the new drivers are welcome... - Merlin: implemented Planar2Chunky blits and hopefully fixed a bug due to a missing WaitBlitter()... - Picasso96Mode: removed obsolete family stuff and enforcer hits - semaphore added to avoid crashes if multiple instances of Picasso96Mode, PMTNG or PabloPrefs try to open the global edit screen simultaneously. - PicassoIV: improved horizontal panning - PiccoloSD64: blit routines slightly optimized Changes in 1.28: - major speed increase: optimized Text(). - fixed KickStart 3.0 only bug which could cause system crashes. - removed potential enforcer hit during swapping of planar screens. - hardware acceleration for monochrome pattern blits (Cirrus only right now). - graphics memory caching mode changed with 040 and 060 CPUs (a big thank you to Didier Levet!). This can lead to significant speed ups. If you want to disable this feature you can set the environment variable ENV:Picasso96/DoNotSetMMU to "Yes". - OS 3.x compatible double buffering implemented. On boards without hardware interrupt support this is not perfect yet. Changes in 1.27: - PicassoIV: PIP reacts better on hardware restrictions. - PicassoIV: max. allowed horizontal resolution adapted. Now screens with up to 2000 pixels are creatable in Chunky and HiColor. - fixed a bug within the memory management, which was introduced in 1.26 and caused a lot of trouble (e.g. with NoMemory screens).
