Mac version of the disposable digital camera mod. PV2Mod is a simple program I wrote to modify files stored on a PV2 camera. It is currently only a Mac command-line program (since OS X, macs have become the choice of many geeks, and I’ve found USB programming for Mac to be very easy). While PV2 can modify any file in the camera’s root directory. Link.
