The main changes in O2EM Launcher 0.4 are the following:

    - Implemented support to the the new options added to O2EM v0.90
(filter, euro mode, screenshots)

    - Disabled the useless console window

    - Changed the screenshot size to the new size used by O2EM v0.90
(320x240)

    - Now if the game is not present in gamelist.ini, O2EM Launcher
will search for an screen shot file based on its crc. If you press F8
in the emulator, the front end will use the new screen shot created by
O2EM.

    - Now it lets you use any bios file (warning if unknown)

    - Improved the CRC tool

    - Created new graphics for the interface

    - Other minor fixes
