Release 43 ("Stockholm")

This is the second release of x16-rom by the X16Community team

  • KERNAL
    • BREAKING CHANGE
      • The keyboard protocol between the SMC and the KERNAL has changed. This release requires a firmware update to the System Management Controller on hardware, or on emulator, release R43 or later.
      • This change also affects how the custom keyboard handler vector works (keyhdl). For details, see Chapter 2 of the Programmer's Reference Guide
      • Your Keyboard will not work unless you are running
        • R43 of both x16-rom and x16-emulator (on emulator)
        • R43 of both x16-rom and x16-smc (on hardware)
    • Build
      • Add git signature to ROM build process
      • Update source to use zp addressing mode where appropriate, which suppresses warnings about using absolute mode for zp addresses.
      • Due to cc65's use of KERNAL RAM locations, .asserts were added to try to stablize RAM locations that are hardcoded in cc65's constants file.
    • Hardware support
      • Additional support for display preferences and keymap stored in nvram
      • Support VPB. Hardware with this design sets the hardware ROM bank to 0 immediately before reading a ROM vector. The previous ROM bank will still be in zp $01 upon interrupt handler entry.
      • Bugfix: fix joysticks always being detected
    • Editor/Display
      • New bordered screen modes to support CRTs
      • New behavior for the END key. END will go to the end of the current line. Shift+END will go to the last line on the screen.
      • PS/2 Delete key now deletes the character underneath the cursor.
      • Blinking cursor should be more visible during movement.
      • Support for automatically setting 240p in NTSC and RGB modes for screen modes that are scaled 2x vertically.
      • New skinny PET style PETSCII and ISO charsets.
      • Replace bold ISO charset [akumanatt]
    • BASIC
      • New logo splash logic for smaller screen modes
      • Show git signature in BASIC splash screen under non-releases
      • REBOOT and RESET behaviors swapped.
      • Add "I" (instrument) to playstring macros for FMPLAY, PSGPLAY, and friends.
      • Bugfix: If unable to read color pref from nvram, use the default white on blue.
      • Show DOS status after SAVE and DOS commands.
      • Modify the output of F-keys in the BASIC editor. Removed F9 for keymap cycling.
      • Bugfix: Better support for reading CBM drives' status with the DOS command.
      • Make FRE(n) always return a positive value.
      • New BANNEX (BASIC annex) for overflow code from BASIC.
      • New commands:
        • MENU - load utility
        • REN - renumber BASIC program
        • LINPUT - Read line from keyboard
        • LINPUT# - Read delimited data from file
        • BINPUT# - Read fixed-length data from file
        • HELP - Show short help blurb and hardware versions.
      • New functions:
        • POINTER() - return pointer to variable structure
        • STRPTR() - return pointer to string variable's data
        • RPT$() - return a string made up of a repeated byte
    • MONITOR
      • Bugfix: Better support for reading CBM drives' status with the @ command
      • Bugfix: Clear bank flags at init [stefan-b-jakobsson]
    • API
      • Allow sprite_set_position to retain existing priority/flip values in attribyte byte 6.
    • GRAPH
      • Fully implement fb_fill_pixels [stople]
