Little John Palm

Little John PalmOS (or LJP in short) is an open source multi-system emulator for Palm OS 5.0 (or newer) devices. It is currently the most sophisticated emulator available for the Palm platform, as it is remarkably stable, very feature filled, and can emulate a wide variety of various gaming platforms. It is free software licensed under the GPL.

Development

Little John Palm is written largely by Yohann Magnien, but several other individuals also greatly contributed, especially alias Tinnus, Henk "metaview" Jonas, and Jeff "Skeezix" Mitchell.

During the writing of Little John Palm, code was taken from the many other open source emulators for other platforms, including Jeff Mitchell's own GuineaPig emulator, another popular multi-emulator for the Palm OS. In that respect, LJP can be considered more of a porting of existing code onto the Palm platform, as opposed to have been written from scratch. However, this is something of a generalization, for while the emulator is largely influenced by existing emulators, much effort had to be made to port it to the Palm platform. As of 2008, the current version is 1.1.

History

Little John Palm was originally a NES emulator for the GP32 called Little John, written by yoyofr. It was then ported to the Tapwave Zodiac, and renamed LJZ (Little John Zodiac). Later it was again ported to the general Palm OS, and renamed LJP. Tinnus started working at 0.92, making a version 0.92T. After Tinnus and yoyofr releasing 1.0 RC2, and Tinnus releasing 1.0 RC3, Henk "MetaView" Jonas took over and released versions 1.0 RC4-9 and 1.0-1.1.

Future

Tinnus had stopped working on LJP, instead working on LJR/LJX (Little John Revival). metaview has taken over updating LJP, and had released 1.0 RC4-9 and 1.0-1.1.
