## Background
DOSBox Pure is a fork of the multiplatform MS-DOS emulator, DOSBox. It was built by Psyraven in 2020 specifically for RetroArch/Libretro and implements advanced features like save states, an on-screen keyboard, highly customizable controller setup or rewinding. DOSBox Pure aims for simplicity and ease of use.

The core automatically executes `DOSBOX.BAT` instead of showing the start menu if it exists in the mounted ZIP or path.
### Loading of dosbox.conf files
If a .conf file gets selected in the frontend, DOSBox Pure will load it directly and run its autoexec commands.
Alternatively, a .conf file can get loaded automatically depending on the 'Emulation > Loading of dosbox.conf' [core option](#emulation-options). There are two modes that can be enabled:
- "Try 'dosbox.conf' in the loaded content (ZIP or folder)" - Will load C:\DOSBOX.CONF automatically if it exists in the mounted ZIP or path
- "Try '.conf' with same name as loaded content (next to ZIP or folder)" - Will automatically load GAME.conf next to GAME.zip if it exists.
### Loading M3U8 files
If the core gets loaded with a `.m3u8` file, all files listed in it will be added to the disc swap menu. The first image will automatically get mounted as the A: or D: drive depending on whether it is a CD or floppy disk image.

If your libretro frontend wants to load the content of `.ZIP` files instead of sending it to DOSBox Pure to load, the files can be renamed from `.ZIP` to `.DOSZ`.
This is especially useful for CD images in ZIP format which RetroArch refuses to append through its `Disc Control` menu. Using an `.M3U8` file (see above) also avoids this problem.

- **Save States Support** [dosbox_pure_savestate] (**Enable save states** | Enable save states with rewind | OFF)
Make sure to test it in each game before using it. Complex late era DOS games might have problems. Be aware that states saved with different video, CPU or memory settings are not loadable. Rewind support comes at a high performance cost and needs at least 40MB of rewind buffer.
- **Loading of dosbox.conf** [dosbox_pure_conf] (**Disabled conf support (default)** | Try 'dosbox.conf' in the loaded content (ZIP or folder) | Try '.conf' with same name as loaded content (next to ZIP or folder))
DOSBox Pure is meant to be configured via core options but optionally supports loading of legacy .conf files.
