Changelog:

  • BUILD
    • Building BASLOAD and X16EDIT now outputs trace headers to facilitate instruction traces in the emulator for those banks. [stefan-b-jakobsson]
  • KERNAL
    • Fix a few issues applying the PS/2 typematic (speed/delay) preference after a boot. [stefan-b-jakobsson]
    • Num Lock can now be turned off.
    • Added extapi command kbd_leds to fetch or set the keyboard LED state
    • Added extapi command scnsiz to override the KERNAL's text resolution
    • ioinit now disables all stock interrupt sources (VERA, VIAs, and YM2151)
    • 65C816 default native NMI handler now chains to the 65C02 one
    • Fixed a bug which caused backspace and quote mode glitches in the BASIC editor when the background color was set to 8 or above.
    • Removed some unused code for softclock and C64 RS-232 [Fulgen301]
  • DOS
    • Added a channel 15 "T" command to return the current position within an open file and the total file size. See the example.
  • FAT32
    • Reworked code to remove indexed reads and writes on the I/O page which reach into banked RAM, which might have side effects on the 65C816.
  • KEYMAP
    • Characters that exist in the layout for ISO-8859-16 that are not in -15 can now be typed [adiee5]
  • BASIC
    • New commands OVAL (filled) and RING (unfilled) which can draw ellipses and circles quickly.
    • Fix POKE to I/O space by using a non-indexed addressing mode. This avoids the extra phantom reads which can have side effects. [Fulgen301]
    • Fixed regression in VPOKE where if PEEK() or POINTER() was inside its arguments. a write could happen to the wrong VRAM address
  • MATH
    • Changed code in fdiv that depended on zeropage wraparound behavior so that it would also work in 65C816 native mode
  • GRAPH
    • GRAPH_draw_oval implementation added
    • Fixed FB_set_8_pixels and FB_set_8_pixels_opaque which did not properly handle VRAM addresses > $0FFFF
  • CHARSET
    • Added katakana character set [adiee5]
  • UTILITIES
    • Stefan B. Jakobsson's X16-Edit has been updated.
    • Stefan B. Jakobsson's BASLOAD has been updated.
