WiiColEm 0.3 + ColecoVision Homebrew Video

WiiColEm Video


To install WiiColEm, simply extract the zip file directly to your SD card or USB device (retain the hierarchical structure exactly).

Cartridge Database

WiiColem ships with a database that contains recommended settings for most commercial cartridges. These settings cover controls mappings, keypad overlays, keypad button descriptions, and advanced settings (whether the cartridge requires an EEPROM, SRAM, etc.).

To view/edit the settings applied for a particular cartridge perform the following steps:

  • Load the cartridge (via the "Load cartridge" menu item)
  • Return to the WiiColem menu
  • Select "Cartridge settings (current cartridge)" menu item
  • Examine the "Control settings" and "Advanced" settings for the cartridge

For more information on mapping controls and creating and/or customizing cartridge settings, see Cartridge Settings.

Default Controls

The following section contains the "default" control mappings for WiiColEm.

It is important to note that if the cartridge that is being loaded exists in the Cartridge Database it may contain non-default mappings.

In-game (Keypad)

The keypad allows you to press keys on the ColecoVision controller keypads. If a description has been provided for the currently selected key it will be displayed above the keypad.

You can select whether you want emulation to pause while the keypad is displayed via the "Keypad pause" option in "Advanced" settings (pausing is enabled by default). This value can be overridden on a cartridge-by-cartridge basis via Cartridge Settings.

NOTE: The "Keypad pause" option is not available when the GX+VI or Double strike (240p) video modes are enabled. (Keypad pause is enabled and cannot be disabled).

  • When keypad pause is enabled, the keypad will be closed when a keypad button is pressed (or the keypad is explicitly closed). It is important to note that the keypad button will continue to be pressed as long as the controller button is held. This is necessary for games like War Room where you need to hold the keypad buttons down to see the different factories, etc. It is also necessary for games that require a longer button press for the selection to register (Star Trek, etc.).
  • When keypad pause is disabled, emulation will continue while the keypad is displayed. The keypad will continue to be displayed until it is explicitly closed. This mode works well for games like Lord of the Dungeon and Ken Uston Blackjack that require lots of button presses.

It is also important to note that commonly used keys can be mapped to Wii controller buttons (see Cartridge Settings).

        Display WiiColEm menu (see above)

In-game (Super action)

Very few games use the "spinner" that is a part of the super action controller. You can enable/disable the "spinner" via Cartridge Settings.

By disabling the spinner, you have more options available for the move controls (Nunchuk analog, both analogs on the Classic and GameCube controllers).

  +       Action

      Display WiiColEm menu (see above)

In-game (Driving / Tilt)

In this mode, you steer by tilting the Wiimote (similar to Excite Truck/Bots). You can adjust the tilt sensitivity via Cartridge Settings.

Tilt   Steer
  Toggle Keypad
  Display WiiColEm menu (see above)

In-game (Driving / Analog)

In this mode, you steer by using the analog controls (Nunchuk, Classic, GameCube). You can adjust the analog sensitivity via Cartridge Settings.

  +       Action
  or       Gas
 or       Brake
      Toggle Keypad
      Display WiiColEm menu (see above)

In-game (Roller)

In this mode, the trackball motion is simulated via analog controls (Nunchuk, Classic, GameCube). You can adjust the analog sensitivity via Cartridge Settings.

  +       Action
  or       Left Fire (2p)
 or       Right Fire (2p)
      Left Fire
      Right Fire
      Toggle Keypad
      Display WiiColEm menu (see above)

In-game (Aquattack)

Aquattack has a very unique control scheme. It uses the keypad buttons to fire in eight different directions. Essentially, it uses the "keypad" as a "d-pad". While the keypad buttons have been mapped to the eight different buttons on the Classic controller (and pro) it is cumbersome to use. In addition to mapping these buttons, a special control scheme has been added to WiiColEm that allows for the use of the right analog stick on both the GameCube and Classic controller/Pro for firing in the eight different directions.

Cartridge Settings

WiiColEm contains the ability to manage per-cartridge settings. The settings that can be edited include:

  • Control settings
  • Advanced settings (Whether it requires an EEPROM, SRAM, etc.)

Control Settings

The following control options are available:

  • The controller type (standard, super action, driving/tilt, driving/analog, roller)
  • Wiimote orientation
  • Sensitivity (Roller and driving controllers)
  • ColecoVision keypad and controller button mappings

When mapping buttons, you map a ColecoVision keypad or controller button to one of the "button groups" listed below. This allows you to map a button once across the different Wii controllers.

You can use the "(View as)" menu item to toggle and view how the ColecoVision buttons are mapped to a particular Wii controller (Wiimote, Nunchuk, Classic/Pro, and GameCube).

Button 1        
Button 2        
Button 3   (n/a)    
Button 4   (n/a)    
Button 5 (n/a) (n/a)    
Button 6 (n/a) (n/a)    
Button 7 (n/a) (n/a)   (n/a)
Button 8 (n/a) (n/a)   (n/a)

SMB (Network support)

WiiColEm allows for loading ROMs over the network via SMB. To enable SMB support, you must edit the "wiicolem.conf" file located in the "/wiicolem" directory and provide values for the following:

  • share_ip
    • IP address of the computer to connect to.
  • share_name
    • Name of the share on the computer.
  • share_user
    • Name of the user to connect as
  • share_pass
    • Password for the user
