DreamShell is a Unix-like operating system, designed for the Sega Dreamcast video game console. It is based on KallistiOS libraries. Originally a command line interface with the ability to run third-party applications, later versions of DreamShell gained a GUI XML-module and support for applications written in the lua-scripts, with the ability to enhance their functionality by using functions of KLF-modules (analogous to DLL in Kallisti OS).

  • DreamShell 4.0.0 Beta 2
  • The first version to include a simple File Manager.
  • Added support for the integrated SD Card. This makes it possible to manage the files on the SD card, the VMU, or another storage device connected to Dreamcast. Supports all major file system capabilities. The file names are limited by 8.3 convention.
  • Added a new XML element <cardstack>
  • Added a loading screen (displayed when the application is loaded.)
  • Added initial support for cursor changes GUI.
  • Fixed parsing of XML in color for items <label> and <input>.
  • Event "onload" (in XML <body>) the application is now running in a separate thread.
  • Rewrote the API functions to work with the console commands and new features associated with the withdrawal of the console.
  • Added ability to "put down" the core of DreamShell.
  • DreamShell 4.0.0 Beta 3
  • SD Card file system no longer limited by the 8.3 standard, making it possible to have long file names and file names using Russian alphabet. Library updated to work with the FAT.
  • File Manager updated. Added new functions to work with files (archiving, decompression, rename) and support for more file formats by loading the appropriate module if necessary.

Fixed modules mp3 and ogg, now when they are loaded into the console commands appear to play these formats, as well as their support is implemented in the file manager.

  • Added a module created from the program VC / DC 0.2 (VideoCD player for the Dreamcast).
  • Added gzip and bzip2 to work with the same name archives.
  • The cursor in the GUI can now be changed at any time.
  • Added new event in XML <body> - "onopen", "onclose", "onunload".

  • Reworked the video rendering. Now it works in a separate process, which will not freeze the OS, and the speed of it has been increased.

  • Added new commands, including:
bios - command allows flashing of the BIOS (if you have bios mod)
gdrip - command to rip GD-ROM to the SD card.
hack - command to hack LBA in binary. Can hack into binary and directly in the ISO image.
ffdev - command to work with the SD card.
dreameye - command to save and delete pictures from the camera Dreameye.
luac - compiler lua scripts into bytecode.

Some internal to external commands were added, so as to facilitate the DS kernel.

  • Slightly refined file manager. There are hints in the toolbar, as well as the title shows the current path. Also, it has built-in support for BIOS flashing (when you click on a file with the extension. Bios) and rip GD-ROM.
