Last Updates (max 5)

(2019-01-17)
  • fix user carts so more than 100 could be loaded
  • change cartridge memory from static to allocated
  • fix large cartridge types
  • minor AMS tweaks
  • add ability to disable bitmap layers
  • read windows text files without line feeds (like xas99 emits)
  • allow headerless files to open as DF128 or IF128
  • additional debug for some exotic disk tracking methods
  • then later the same day, fix the 9901 timer reset so CS1 works again

  •  
    (2018-10-13)
  • v399.004
  • reset more of CRU on menu-reset
  • add 9901 timer to the debug register pane
  • don't reset the 9901 timer every time you leave timer mode (fix for CamelForth)
  • more disk DSR warnings (hate that disk DSR so much...)
  • allow the disk corruption break option to catch the DSR warnings too
  • update manual for 9901 line

  •  
    (2018-09-08)
  • fiddled with AVI audio, but no improvements. AVIs updated to 60hz otherwise.
  • fix strange speedups - code that read the VDP status register was giving about 50% bonus cycles to the VDP. The more often you read it, the faster you went ;)
  • change waitable timer to a smaller value
  • remove the forced time on CPU_MAXIMUM. Now it actually runs maximum speed. And stays in sync.
  • add some comments to remind myself what the heck I was thinking in the 'full frame' update for overdrive

  •  
    (2018-08-18)
  • Added hotkeys for Paste (control-F1), Debugger (control-Home), and copy screen (Control-F2)
  • added copy screen function (hold SHIFT for BASIC offset)
  • added Tape menu and added STOP and PLAY functions (sorry, not tested)
  • debugger adds view->ASCII Add Screen Offset for BASIC checkbox (not saved)
  • fix display of active GRAM pages when opening dialog
  • 32MB AMS implemented - enabled it for now (we already used to reserve 16MB as it was)
  • re-arranged VDP gettables to be more convenient and less redundant
  • added NOCR or NOLF options to clipboard - if you open it as
  •  
    (2018-02-17)
    -Fix build options to work on Windows XP again
