The wonderful e[mulator] has been updated to v0.82e today by developer e. If you've missed this one before or are a newcomer to the homebrew scene, e[mulator] is a multi-platform emulator supporting Gameboy, PCEngine, WonderSwan, Sega Master System, Sega Game Gear, and NES.

It also currently supports Atari Lynx but e has noted that this feature is still quite buggy; although a fix added since the last version should fix it. It is also supposed to support NeoGeo Pocket, but e has pointed out in his readme that it's still very slow and doesn't have savestate support.

Here is the changelog for this version:

• Bug fix to characters that weren't displaying correctly
  
• WS : SRAM retention, state retention and operation verification being completed
• Lynx: Operation of the Lynx part of this emulator should work correctly.
