Why does my Handspring Visor ROM not work in the PalmOS Emulator?

The PalmOS Emulator's ROM transfer program is designed to work with devices made by Palm, Inc. This transfer tool may not work correctly with PalmOS-based devices made by other manufacturers, since they may store and manipulate the ROM differently in their devices than the ROM transfer program expects.

For instance, Handspring's Visor uses a non-flashable ROM, while Palm's own devices use a flashable ROM.

You should use a ROM from a Palm, Inc. device and/or download a ROM from Palm's developer Web site. Details on how to do this are available in this related FAQ item.
