  1. Version 1.0.0

    75 downloads

    This is a snapshot and executable file of a Commander X16 Color Palette Editor which was built from C source files and is compatible with Release 37. The up/down and left/right cursor keys are used to move between palette entries which are displayed on a color grid. The currently selected palette entry is surrounded by a box in the color grid and is also displayed at the top of the color grid with the associated index and RGB values displayed to the left and the associated palette data displayed to the right. All values are displayed in decimal. The Commander X16 Color Palette Editor can be used to view the default color palette and to change the RGB values of the entries if desired. The RGB values of the currently selected palette entry can be changed with the r/R, g/G, and b/B keys which increment/decrement the red, green, and blue components respectively. The palette data can be exported to a BASIC program which can be used to load the modified color palette for a user application or before running the Commander X16 Color Palette Editor again. The palette data is also exported in a format more amenable for inclusion into a C program. The palette data exported in the BASIC program format can be reloaded into the Palette Editor via the following steps: (1) start the emulator using the -echo option; (2) paste the BASIC program into the emulator; (3) execute the RUN command; (4) execute the NEW command; (5) load the Palette Editor; and (6) execute the RUN command. The Palette Editor will then pick up the palette data that was loaded into the color palette by the BASIC program. The following two steps are an alternative to step (2) above: (2a) paste the BASIC program into a text file; and (2b) use the emulator -bas option to load the program from the text file when starting the emulator. This alternative approach is recommended if you're having problems with the emulator corrupting lines when pasting the BASIC program directly into the emulator. The palette data is automatically exported when resetting to the default palette and when exiting the palette editor to avoid accidental loss of data. The exported data can be recovered before reloading and restarting the palette editor as described above.
  2. RGB Grid View File This is a snapshot and executable file of a Commander X16 RGB Color Grid application which was built from C source files and is currently compatible with Release 37. The green and blue values are the vertical and horizontal components of the color grid respectively, and the entire color grid is updated when the red value is changed. The green value is selected via the g/G keys or the up/down cursor keys and the blue value is selected via the b/B keys or the right/left cursor keys. The red value is selected via the r/R keys or the +/- keys. The F1 key affects the display mode associated with the red value. In the default display mode the red value of the first entry in the palette is always set to 0 and the screen background and upper-left cell of the color grid are always black. In the alternate display mode the red value is populated in the first entry in the palette which affects the entire screen background as well as the upper-left cell of the color grid. The selected red value affects the color of the screen text in the default display mode as well as the alternate display mode. The alternate mode allows the shades of red to be viewed when the green and blue components are both zero, but the default mode is preferred when viewing all other color combinations. The color currently selected is surrounded by a box in the color grid and is also displayed at the top of the color grid with the associated RGB values displayed to the left and the associated palette entry displayed to the right. All values are displayed in decimal. I developed the Commander X16 RGB Color Grid application as an exercise to learn more about the operation of the VERA video-module and also to help me in choosing color shades for my screen and sprite graphics and easily determining the associated values for the palette.
