bug: stop compact flash emulation from accidentally scanning c:\ sometimes

enh: add support for game database for improved save type detection

enh: hotkey for limit framerate toggle

enh: remove stop and reset toolbar buttons which were accidentally getting used

enh: additional complexification to desmume's behaviour run from a console prompt. whether it's better is uncertain.

enh: add support for cheats databases

enh: improvements to ram search tool

enh: preliminary support for varying stylus pressure

enh: add [Display] Show Console=1 to ini file

enh: more graceful cheat parsing and add some hotkeys

enh: improve FPS throttle feedback and granularity

enh: add lua menu API

enh: hud font switching

enh: add optional file association for .nds to path config dialog

 

Cocoa:

enh: Big update to cocoa frontend. Pretty much entirely new. (rogerman)

NES emulator.

0.046 (4/7/2012)

• VRC7 audio (Lagrange Point) sounds much closer to the real thing
  
• Fixed several UI bugs:
  
  • menu bar is no longer visible in fullscreen on some systems
    
  • no longer possible to load a ROM or open the preferences window in fullscreen as this could sometimes cause hangs
    
  • Full screen now defaults to maintain aspect ratio (doesn't stretch and look terrible on widescreen displays)
    

  [*]Now handles mising JInput library more gracefully

  [*]NTSC filter is somewhat faster (still not really real time) and disables dot crawl in Battletoads as it should.

  [*]Changed audio core so it shouldn't clip with sound filtering on any more

  [*]Found a solution to the packaging problem! Library folder is no longer necessary.

Next version I will be switching to LWJGL for the interface as it should add

a decent speed improvement and the NTSC filter will be MUCH faster if written

as a shader.
