Handy is dedicated to emulating the Atari Lynx hardware on a standard PC. The software was originally developed by Keith Wilkins [1] and was released under the GPL on 14th April 2004.

Additional changes developed by the SDLEmu team [2].



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

Cartridge images must be placed in the roms directory (/wiihandysdl/roms).

For the emulator to function, you must provide the "Atari Lynx boot rom" (lynxboot.img). This file must be obtained and placed in the WiiHandy directory (/wiihandysdl).

Cartridge Database

WiiHandy ships with a database that contains recommended settings for several cartridges. Specifically, it should contain the proper orientation (rotation) for any cartridges that don't use the typical horizontal orientation. This eliminates the need to modify cartridge header information to have a game rotate properly.

It should also be noted that if you look inside the database file, the hashes (MD5) being calculated do not include the 64-byte header for the purposes of increased compatibility. If you want to view the hash for a particular cartridge enable the "Debug mode" option under "Advanced". The hash will be displayed when the cartridge is playing.

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 WiiHandy menu
  • Select "Cartridge settings (current cartridge)" menu item
  • Examine and modify settings for the cartridge

Cartridge/ROM Compatibility

It is worth noting that there are quite a number of bad Lynx ROM dumps floating around. In an attempt to reduce the incorrect reporting of incompatible games due to bad dumps, I have created the following page:

Cartridge Compatibility

This page lists each game that has been tested with WiiHandy along with its associated hash values (one for the full file, one that excludes the header information).

Enable the "Debug mode" option within the "Advanced" menu to view the hash (excluding header information) when a catridge is playing.

I would really like to resolve these issues, and it would be great to work along with the people who are experiencing them to get them resolved.
