How to configure Picasso96

• the settings file containing all display mode information which is usually stored in SYS:Devs/Picasso96Settings
• the tool types for the monitor driver which is normally in SYS:Devs/Monitors/<your_card_name>
• the optional environment variables which can be found in ENV:Picasso96

• The settings file containing the screen modes is maintained by Picasso96Mode or PicassoModeTNG. It will not be changed during updates if not explicitly selected.
• The tool types are initialized during the first installation of Picasso96 and will not be changed during updates.
  Available are:
  • SOFTSPRITE: use software sprite emulation in all modes.
  • BIGSPRITE: double the size of the sprite (ECS sprite only)
  • BORDERBLANK: force board to always (Yes) or never (No) display a border, defaults to do the same as the system.
  • DISPLAYCHAIN: if set to "no" the Amiga or other boards will never been shown by the board switch. This is used for multiple monitor configurations.
  • IGNOREMASK: if set to "yes", masked blits are treated like unmasked ones for speed reasons.
  • NOPLANAR2CHUNKYBLITS: use CPU routines instead of on-board blitter for that purpose. Might be faster in certain configurations.
  • NOBLITTER: if set to "yes" the on-board blitter will never be used. Activate this only when absolutely necessary.
  • BOARDTYPE: the type of the board to configure by this monitor driver, e.g. "PicassoIV".
  • SETTINGSFILE: name (and path) of the settings file. Defaults to SYS:Devs/Picasso96Settings.
  
  
• The environment variables are only optional and are modified manually from a CLI window by calling "SetENV Picasso96/<option> <value>".
  If this does not work you probably do not have a directory named Picasso96 in your ENV: directory which needs to be created.
  A GUI alternative is the Picasso96Prefs program.
  You can store those settings by copying them to ENVARC:. This way they will be reactivated each time you reboot your system.
  Valid options are:
  • AmigaVideo: if set to "31kHz", the Amiga will be set to a MULTISCAN-like mode when Picasso96 screens are shown. This is necessary if you want to have a high audio sampling rate because the Amiga audio is coupled with the Display DMA. Only set this if you do not have a 15kHz monitor like the A1084 attached to the Amiga video port.
  • BlackSwitching: if set to "Yes", the display will be set to black when screen switches involve a memory transfer of the new screen to the board. This way it might look better. Use it as you like it.
  • DirectColorMask: if set ("Yes"), masked blits are supported in HiColor and TrueColor, too, but this will slow down operations like shell scrolling. Use only if absolutely necessary.
