Setting up "DOSBox Gridc"

2019-04-12

GOG.com

To setup DOSBox Gridc with releases of DOS games from GOG.com for play in split screen, follow these instructions. It's assumed that both the game and Grid Cartographer (v4 or later) are installed and working correctly.

  1. Download a copy of DOSBox Gridc from the Grid Cartographer download page: http://gridcartographer.com/download/#clients
  2. Locate the installation folder of the game. If using GOG Galaxy to install the game this can be done by selecting the game, selecting the MORE drop-down menu, choosing Manage Installation then selecting Show Folder.
  3. In the installation folder should be a sub-folder called DOSBOX. This is a standard version of DOSBox and is lacking the features needed to integrate with Grid Cartographer. Delete this folder (optionally making a backup so a clean install can be restored).
  4. Extract the contents of the DOSBox Gridc archive and copy the enclosed DOSBOX folder to replace the one that was just deleted.
  5. Look at the files in the installation folder (not in the newly created DOSBOX folder) and locate the dosbox.conf file. Note there may be multiple .conf files in the folder and they may be named slightly differently, in which case choose the largest file. Open this .conf file in a text editor.
  6. Search for the line that begins output=. This will be under the [sdl] section near the top of the file. Remove the value after the equals sign and replace it so that the whole line reads: output=gamelink. Save the changes to this file.
  7. Launch the game as normal from the desktop shortcut, start menu or from within the GOG Galaxy client. A DOSBox window should open with the logo inside which will stay. You should hear audio from the game but not see a picture.
  8. Start Grid Cartographer. The game will be visible in a viewport by selecting the arrow icon in the top-right and choosing the LibRetro (or Game Link) option.

Note: By default, you will be informed that a game is running and given the choice to start a new map file and also whether you'd like to switch to a split screen layout.

Steam

To setup DOSBox Gridc with games released on Steam, follow these instructions. It's assumed that both the game and Grid Cartographer (v4 or later) are installed and working correctly.

  1. Download a copy of DOSBox Gridc from the Grid Cartographer download page: http://gridcartographer.com/download/#clients

  2. Open the Steam client. Select the game in your library, right click and choose Properties.

  3. On the properties dialog box, select the Local Files tab. Click the first button on the page labelled Browse Local Files. A file explorer window should appear.

  4. Find the following files: dosbox.exe, SDL.dll and SDL_net.dll. The files will either be in the newly opened folder, or in a sub-folder. Publishers vary the locations of these files so you may need to use the search function to assist you.

  5. Extract the contents of the DOSBox Gridc archive into a temporary directory.

  6. Carefully copy/replace the files: dosbox.exe, SDL.dll and SDL_net.dll with the copies from DOSBox Gridc. Make sure to copy/replace all three files.

    • At time of writing (November 2018) the Steam releases of Wizardry 6 and Wizardry 7 are distributed with an out-of-date copy of DOSBox Gridc. To ensure correct operation, please delete the file dosbox_gamelink.exe from the Steam folder (in addition to replacing the files listed in step 6).
  7. Look again at the files in the Local Files folder and locate the dosbox.conf file. Note there may be multiple .conf files in the folder and they may be named slightly differently (typically with the game name as a suffix). If there is a choice, select the largest file. Open this .conf file in a text editor.

  8. Search for the line that begins output=. This will be under the [sdl] section near the top of the file. Remove any value after the equals sign and replace it so that the whole line reads: output=gamelink. Save the changes to this file.

  9. Launch the game as normal from the Steam client. A DOSBox window should open with the logo inside which will stay. You should hear audio from the game but not see a picture. This is normal.

  10. Start Grid Cartographer. The game will be visible in a viewport by selecting the arrow icon in the top-right and choosing the LibRetro (or Game Link) option.

Note: By default, you will be informed that a game is running and given the choice to start a new map file and also whether you'd like to switch to a split screen layout.
