==Trance JIT==
''[[Trance JIT]]'' is a [[MorphOS]] [[Just-in-time compilation|just-in-time]] (JIT) [[compiler]], or code translator, for running 68k applications within the MorphOS environment. It has been part of the MorphOS operating system since MorphOS 1.4.<ref>{{cite web |url=http://www.ann.lu/comments2.cgi?view=1060418084&category=files |title=MorphOS 1.4 available |date=9 August 2003 |access-date=2010-07-28}}</ref>

MorphOS has a fully integrated 68k emulator to run many Amiga applications, which were almost exclusively compiled for the 68k processor, though MorphOS runs on [[PowerPC]]. Trance supplements this function by adding JIT compiling, increasing the speed of the emulation. It does not interfere with the full integration of 68k and PowerPC tasks MorphOS provides.<ref name="WhatsThat"/>

Trance exists in the form of an executable, run during boot, and a shared library. Although it is not technically part of the kernel, and MorphOS can be run without it, Trance is considered a fundamental part of MorphOS and one of its most powerful features.

Compatibility of Trance is considered to be very high and there are few to no 68k instruction sequences or applications which cause it any problems. It is also considered to be very fast, with users noticing few differences between 68k programs and native PowerPC code.<ref>

Trance was developed by Ralph Schmidt and Teemu Suikki, with minor support from other MorphOS team members, Mark Olsen, Sigbjørn Skjæret, and Harry Sintonen.
