Changes are as follows

• Auto checking for incorrect PSP registry version at startup. User is kicked if a 1.50 registry is present in a 2.71 SE firmware installation, or vice versa. A prompt is given to restore registry settings in the XMB menu.
• Implementation of custom coded '6AM Sample Player'. Sound effects are resampled louder and clearer. Sound sample files are built into the program EBOOT.
• Mikmod audio library is now used soley to play demo music.
• Startup file checking sequence is faster since there are less external files to validate.
