Palm OS Emulator emulates Motorola 68000-class devices and has intimate knowledge of Palm OS's inner working, allowing for the close monitoring of correct application operation.
Unlike Xcopilot (another descendant of Copilot), Palm OS Emulator will not boot uClinux.
All versions of Palm OS Emulator require a file containing the ROM image to boot.
ROM image files can be obtained from PalmSource (now part of Access Co., Ltd), or downloaded from a real Palm device.
