PSPKVM is a Java 2 Micro Edition (J2ME) CLDC/MIDP Emulator for the Sony PSP.

Changes:

The Danzeff and semichordal boards now implement ‘smart display’ in which they move out of the way of input in large text fields as you type.
Icons have been added to the configuration and network setup screens in an attempt to make this a little easier to use for non-English users, until we can get some translation going for these screens.
Network setup has been overhauled, in an attempt to address occasional issues with lost connections that cannot be reestablished without a VM restart. In case of a lost connection, you should now be able to reconnect from the Wifi manager midlet, without restarting the VM. Please report whether this works for you in the shoutbox at http://pspkvm.org
The Danzeff display has been made slightly more compact as compared with the previous build.
The readme has been updated and is now included with the binary packages.
