Exceed have released the worlds first Atari Lynx Emulator for the PSP, heres whats featured etc:
– L button: Game selector list, Circle selects the game
– Triangle: Picture size large/small
– Circle: Turn sound on or off
– Cross = A button
– Square = B button
– R button: Pause
– Select: Option 1 button

The emulator has a nice file selection screen but you will need the Bios for the Atari Lynx, it has sound and one ultra cool option, basically you can change between a normal screen and the game inside the Atari Lynx
