PCSX2 v1.4 Re-Recording v4.2 is released. PCSX2 is an open source PlayStation 2 (PS2) emulator for the Microsoft Windows and Linux operating systems. With the most recent versions, many PS2 games are playable (although speed limitations have made play-to-completion tests for many games impractical), and several games are claimed to have full functionality. PCSX2 Re-Recording is a special version of PCSX2 with many new features such as input rerecording, cheat support, RAM search, RAM watch, customizable hotkeys, etc.

PCSX2 v1.4 Re-Recording v4.2 Changelog:
This version adds the gui library to Lua.
See the wiki for available functions.
This function also adds (and reorganizes) menus to the main frame. It also slightly modifies GSdx to save a snapshot to a specified file (no automatic name, in this case).
