Descended from Copilot, '''Palm OS Emulator''' is used for writing, testing, and debugging Palm OS applications. Palm OS Emulator emulates [[Motorola 68000|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]]. By using  [[Skin (computing)|"skin"]] files, Palm OS Emulator could very closely mimic the appearance of many models of Palm handheld.

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. Palm OS Emulator supported Palm models produced by Palm, [[Handera]], [[Handspring (company)|Handspring]], and [[Symbol (company)|Symbol]]. Palm OS handhelds produced by [[Sony]] (the [[Clie]] line) were supported by a separate, Sony-specific [[Fork (software development)|fork]] of Palm OS Emulator.

Both Copilot and Palm OS Emulator are released under the [[GPL]] v2. Versions were developed by Palm, Inc. for Windows, Macintosh, and Unix platforms. The Sony fork was only released for Windows.<ref>{{cite web |last=Desrosiers |first=David A. |title=Sony GPL Violation with the PalmOS Emulator |url=http://docs.gnu-designs.com/sony/ |url-status=dead |archive-date=4 March 2016 |archive-url=https://web.archive.org/web/20160304074251/http://docs.gnu-designs.com/sony/ }}</ref>

Palm OS Emulator supports Palm OS 4.x and earlier.<ref>{{cite web |title=Palm OS Emulator |website=PalmSource |url=http://www.palmos.com/dev/tools/emulator/ |url-status=dead |archive-date=11 January 2007 |archive-url=https://web.archive.org/web/20070111221204/http://www.palmos.com/dev/tools/emulator/ }}</ref> It cannot support Palm OS 5.x and later, as those versions are based on the ARM processor. PalmSource provides simulators for Palm OS 5.x and up, where the Palm OS has been recompiled to run natively under Windows.

Linux, Mac, and Windows versions of the emulator were included on the CD-ROM included with ''Palm Programming: The Developer's Guide'',<ref>{{cite web |title=Palm Programming ReadMe |publisher=O'Reilly Media |url=http://ftp.oreilly.com/pub/examples/9781565925250/CDROM/Palm%20Programming%20ReadMe.txt |format=TXT |access-date=21 September 2017 }}</ref> published by [[O'Reilly Media|O'Reilly]] in 1999.<ref>{{cite book |last1=Rhodes |first1=Neil |last2=McKeehan |first2=Julie |date=1999 |title=Palm Programming: The Developer's Guide |publisher=O'Reilly |isbn=978-1-56592-525-0 |oclc=76012014 |url-access=registration |url=https://archive.org/details/palmprogrammingd00rhod }}</ref>
