  • MonitorGui 1.12 set "pointer in screen" status; use new icon; changed some "config" menu item positions.
  • TrapDispatcher 1.05 do not set pointer position if mouse not in screen..

v.1.14

Bug fixes.

• SMSQmulator
  • MonitorGui 1.11 correctly set status of read only warning item on startup; handle Shift tab, shift del, alt del, shift alt del.

v.1.13

  • QxlWinDriver 1.03 possibly warn if drive is read only.
  • Warnings 1.01 adjusted to suit - new warning item disk is read only.
  • MonitorGui 1.10 better mouse handling when in double sized mode ; new warning item (drive is read only) ; set screen object coordinates when window moved /resized ; ignore mouse moved event when mouse position in wdw is changed from within SMSQE via sptr.

  • NfaFileheader 1.03 correct length of filename used in getSMSQEFilename (stopped makeDirectory from working).

  • CLR sets the Z flag correctly

v.1.10

• SMSQmulator
  • SMSQmulator 1.06 fixed getBootDir for windows where the filename doesn't always contain java.io.File.separators but "/" instead. If an ini file is present on the boot device, always use that, even for saving the ini file.
  • MonitorGui 1.09 in memsize choice box current memsize is the default value.
  • QxlWinDrive 1.00 unuse : set some objects to null, allows for GC.

  • Monitor 1.03 caps lock status is written directly into system variables (!).

v.1.05

• M68000K
  • Replaced some instructions with my own (MOVE,MOVEM,JSR,MOVEQ,CMP,MOVEA,TST). The speed increase is minimal.
• SMSQE
  • smsq_java_driver_scrap_asm : implements the JVAMBAR keyword.

v.1.04

Pure bugfix release.

Repaint is called by the interrupt thread. Clut initialized at component creation, general cleanup.Faster moveblock & fillblock routines. Attempt at general speedup by writing to the bufferedImage.raster.databuffer directly
  • MonitorGui 1.03 mention the QL colour mode xsize requirement and warn that machine will be reset when screen size is changed. 1.04 screen size (but not resolution) changes when the window is resized. Possibility to double the window size (not resolution) introduced.
  • XfaFile 01.02 dirs are handled differently : read the entire dir in a go; also, check for pending input handled correctly even for dirs. Creates files with QemuFileheaders by default. Default fileheader = QemuHeader, not SFA header
  • TrapDispatcher 1.03 implement trap#5, d0=18 (read rtc directly from java).
  • QL50HzInterrupt 1.01 no longer set time each time this is called. It calls screen.repaint every secont time it executes
