I want the game to fill the screen

Switch to fullscreen mode by pressing ⌘F. You can press it again to return to a window.

My game runs too fast or too slow

You can speed up and slow down the emulation by pressing ⌘⇡ and ⌘⇣. You will see a speed indicator in the title of the window go up or down accordingly.

The mouse pointer behaves weirdly

• Switch to fullscreen mode by pressing ⌘F.
• Or, hold down ⌥ and click the window to lock the mouse. This prevents the mouse pointer from leaving the edges of the DOS window. You can ⌥click again to release the mouse.

I have a one-button mouse but my game needs two buttons

Hold down ⌘ as you click the mouse button to imitate a right-click.

I keep switching OS X Spaces while playing

The default controls for some DOS games can conflict with the Ctrl⇠⇡⇢⇣ shortcuts used for switching OS X Spaces. To avoid this you can:

• Switch to fullscreen mode by pressing ⌘F.
• Or, change the controls for your game to avoid using Ctrl.
• Or, change the Spaces shortcut keys in the Exposé & Spaces preferences pane to avoid using Ctrl.

The function keys don’t work

Newer Mac keyboards reserve the function keys for OS X functions like Exposé and Dashboard.

To get these keys to work normally in DOS, hold down the fn key as you press the function key. You can toggle this keyboard behaviour under the Keyboard & Mouse pane in System Preferences.

If you have manually assigned a function key to something in OS X, it may not be affected by the fn key. In this case, hold down ⌘ as you press the function key.

My keyboard types the wrong characters for some keys

Boxer emulates an MS-DOS PC keyboard layout, so special characters (such as punctuation) are sometimes in different places than your Mac keyboard. Try nearby keys to find the character you’re looking for. If you have trouble finding \, you can use / for file paths instead—just like the OS X Terminal.

The CD music for my game does not play

Unfortunately, Boxer currently does not support audio tracks on CD-ROMs. Many DOS CD-ROM games use CD audio tracks for music but will be unable to play them in Boxer.

The audio tracks are still available in OS X, and as a workaround you could play the tracks in iTunes while playing the game. Many games also have an option to play lower-quality MIDI music instead of CD audio.

My game asks me to swap CDs, but doesn’t recognise the new CD

Boxer’s support for multi-CD games is currently very limited. However, you could try one of the following:

• Press ⌘R after swapping the CD: this will refresh the DOS filesystem to reflect any changes to files and folders.
• Quit the game and relaunch it with the new CD in the drive: then reload a saved game at the point where you were asked to change CDs.
• Import the first CD into the gamebox then copy the contents of the other CD(s) into the imported folder. The game may treat this combined CD as whichever disc it is looking for at the time.
