Main differences:

BREAKING CHANGE: The zero page and $0200+ layout has changed completely and is now incompatible with the C64.

Emulator:

  • PS/2 mouse
  • support for text mode with tiles other than 8x8 [Serentty]
  • fix: programmatic echo mode control [Mikael O. Bonnier]

ROM:

  • new layout for zero page and KERNAL/BASIC variables:
    • $00-$7F available to the user
    • ($02-$52 are used if using BASIC graphics commands)
    • $80-$A3 used by KERNAL and DOS
    • $A4-$A8 reserved for KERNAL/DOS/BASIC
    • $A9-$FF used by BASIC
  • new BASIC statements:
    • SCREEN <mode> (0: 40x30, 2: 80x60, 128: graphics)
    • PSET <x>, <y>, <color>
    • LINE <x1>, <y1>, <x2>, <y2>, <color>
    • FRAME <x1>, <y1>, <x2>, <y2>, <color>
    • RECT <x1>, <y1>, <x2>, <y2>, <color>
    • CHAR <x>, <y>, <color>, <string>
    • MOUSE <n> (0: off, 1: on)
  • new BASIC functions:
    • MX (mouse X coordinate)
    • MY (mouse Y coordinate)
    • MB (mouse button; 1: left, 2: right, 4: third)
  • new KERNAL calls:
    • MOUSE: configure mouse
    • SCRMOD: set screen mode
  • new PS/2 mouse driver
  • charsets are uploaded to VERA on demand
  • GEOS font rendering uses less slant for faux italics characters
