How to run DOS games in Batocera or Recalbox 4.1

You can run fullscreen DOS games in Batocera or Recalbox (4.1 or newer).
You need copy them like this:

1. Select /recalbox/share/roms/dos/
2. Create a folder with the name of the game adding ".pc" (like  galaxia.pc)
3. Copy all the files of the game to this folder.
4. Create a dosbox.bat file, these file must content the fullname of the executable file (like GALAXIA.EXE).
5. Update games in recalbox/batocera menu.

We need repeat steps 1 to 4 for each game we add, and do the step 5 when we finished.

Note: Don't use notepad for Windows because this buggy software can add strange and invisible characters. Better use a good text edit like jEdit.

Run old DOS games in GNU/Linux with DosBox

We can run old DOS games and utilities with 'DosBox'

You can install it on Ubuntu or Debian from Linux console with the command:

sudo apt-get install dosbox

Make a folder like $HOME/dosutils, and copy all the DOS software, each program in a separate folder.

To run DosBox just type 'dosbox' and  type this command in DOS console to mount C:

mount c /home/yourusername/dosutils

We can automatize the booting of software with $HOME/.dosbox/dosbox-x.xx.conf config file.

This file have several sections and parts, there are the most interesting ones:

• fullscreen : DosBOX may boot in fullscreen changing this. You can toogle between window and fullscreen pressing Alt + Enter keys
• [autoexec] : all the lines you put down of this section with run after DosBOX boot, for example:

mount c /home/yourusername/dosutils
c:

If you see that your game runs more slowly than usual yo can increase the speed with CTRL + F12 keys.

There is a lot of DOS games and general software in public domain, free software, etc... for example Champ Games.
