User guide

Install MIDlet from JAR file

Copy the JAR file to Memory Stick.

In AMS, select the first item "Install Application".

Input the full path name of the JAR file. For example: ms0:/abc.jar, means to install MIDlet from abc.jar which is copied to root directory of Memory Stick.

Click Right Soft-button and select "2 Go to" from the popup menu, then follow the steps on screen.

Input text

You can't use Qwerty input method on PSP since it's lack of standard keyboard, but there's still other input methods available.

In any text input sence, you can popup the menu by Right Soft-button, and change to another input method.

It is suggested to use "abc" to input alphabetics, just like you've done on your phone, input english characters by 0~9,#,* keypad.

Multi tasking

In an application, press L+R will put current running MIDlet to background, and AMS screen will be shown.

The background running MIDlet is shown in high-lighted, and you can choose another MIDlet to run without stop the previous MIDlet.

To bring a background running MIDlet to foreground, just click the MIDlet item from AMS is ok.

Known issues

  • sceIoRename, which is used in javacall_file_rename(), doesn't work properly somehow.
  • javacall_file_truncate doesn't ported, so some file truncating operation, such as some RMS operations, may not work as expected.



  • Enable browse and select JAR from local file system, don't have to input the full path name of JAR file now.
  • A little optimization of RMS speed.
  • Separate MIDI config and instrument files from binary bundle to decrease the size, and make you not have to download them for every release.
