These settings control the type of Motorola 680x0 CPU which will be emulated.



CPU Type

24 bit addressing is used mainly by the 68EC020 CPU such as the A1200.

More compatible is only available when the CPU type is a 68000. Some games and demos require this setting for proper compatibility.

JIT can be enabled to access the Advanced JIT settings if the 68030 or better is selected (See below).

68040 MMU enables the Memory Management Unit of the 68040 for operating systems like Linux on the Amiga. It is not compatible with JIT.

Unimplemented CPU emu emulates the full 68060 CPU (in case you forget to load Setpatch and 68040.library and 68060.library).



More Compatible is available if a FPU is selected. Some applications require this for proper compatibility.

Unimplemented FPU emu emulates the full 68881 FPU (in case you forget to load Setpatch and 68040.library and 68060.library).


Cycle-Exact CPU Emulation Speed


PPC CPU Settings

The Blizzard PPC has a 68040/060 and PowerPC 603e at 160, 200 or 240MHz with upto 256 MB RAM. The Cyberstorm PPC has a 68040/060 and a PowerPC 604e at 150, 180 or 200 Mhz with upto 128MB RAM. A seperate qemu-uae.dll file in plugins folder is required for PPC emulation using QEmu.

Sets level of idle mode for the 680x0 processor.

CPU Emulation Speed

CPU Idle You can adjust the idle status of the CPU with this slider. This feature can be useful on notebooks to keep the CPU cooler. See the Hints For Power Users page.


JIT Settings

Due to the importance of the JIT engine and its complexity, it has its own page where you will find a description of its possibilities.
