ProfileEditCPU

Profile editor dialog page "CPU"

On this page you can setup how DOSBox should emulate the CPU for the game you want to run.

• Emulation core
  In this box you can choose the emulation core you want to use.

  • Auto: DOSBox will choose the core type automatically.
  • Normal: DOSBox will execute the game instructions on a virtual CPU step by step. All games should run with this core type but this type will bring a big slow down of the emulation.
  • Dynamic: DOSBox will try to execute the game instructions directly on the real CPU. This emulation type is very fast but can have problems with some games. Unless you do not experience any problems with a game you should use this emulation type.
  • Simple: DOSBox will run the game on a virtual CPU core just like "Normal", but the CPU emulation is much more simple (and therefore faster).

• CPU cycles
  In this box you can enter the amount of instructions DOSBox shall try to emulate each millisecond. Setting this value to "Max" will make DOSBox automatically run as many cycles as possible. Setting it to "Auto" will make DOSBox try to automatically detect the needed number of cycles and will switch to "Max" if appropriate.

• Increate CPU cycles
  In this box you can enter the amount of cycles DOSBox will increase the total number of cycles emulated per millisecond when pressing Ctrl+F12 inside DOSBox.

• Decrease CPU cycles
  In this box you can enter the amount of cycles DOSBox will decrease the total number of cycles emulated per millisecond when pressing Ctrl+F11 inside DOSBox.

• **CPU type **()***
  From this dropdown box you can choose the CPU type DOSBox should emulate.

The option marked with (*) is only visible if the corresponding DOSBox CVS features is enabled on the DOSBox CVS features page of the program options dialog. The official DOSBox 0.72 build delivered with DFendX does not support is special setting.
