This is a computer program, works perfectly on windows xp, enables u run MIDP 2.0 and MIDP 1.0 with CLDC 1.0 java apps and games that run on ur phones to run on your computer... http://kwyshell.myweb.hinet.net/Download/MidpX/MidpX.exe that is the link to download the 1.5mb setup file for the appllication, don't open the application itself, but the MIDP java file e.g Real Football 2005.jar will open with MIDP X when it is installed on ur system...
