Dc Bios Bin
The Sega Dreamcast is a 6th generation home video game console released by Sega in 1998. It is notably the last console that Sega produced.
Correct files dcflash.bin and dcbios.bin (check the values of md5sum). Also, try deleting all dcnvmem.bin files in the system/DC catalog. Once you save in the VMU slot with any game, that VMU becomes unavailable the next time you download the emulator. The fix for this is to include the main option. Full set of Sega Dreamcast BIOSes for use with Demul. All files are properly named and ready to use. Sega Dreamcast BIOS. Code: Select all emulator mappingname = RetroStone Controle btnescape = 314 dreamcast btna = 304 btnb = 305 btnc = btnd = btnx = 307 btny = 308 btnz = btnstart = 315 btndpad1left = btndpad1right = btndpad1up = btndpad1down = btndpad2left = btndpad2right = btndpad2up = btndpad2down = axisx = 0 axisy = 1 axistriggerleft = axistriggerright = compat btn.

Emulators: Reicast, lr-flycast
Reicast can be very laggy and buggy, but some games work great (see compatibility list below). Pi 2 or later is required.
Audio is choppy and not great, and degrades the longer the emulator is in use. Restarting the emulator (and ultimately the Pi) may become a good idea after a couple hours of gameplay. There is a memory leak somewhere in the Reicast code. Low screen resolution are recommended to get best performance. Performance greatly suffers if HD resolutions are used.
lr-flycast is can be found in the Manage Optional Packages menu in the RetroPie Setup Script.
ROMS
Accepted File Extensions: .cdi .chd .gdi for Dreamcast ROMs, .zip for Naomi/Atomiswave games.

DREAMCAST COMPATIBILITY LIST feel free to contribute to the list.
CHD files
Both Reicast and Flycast have support for the CHD (V5) archive format. This format will save space and allow you to keep your Dreamcast ROM folder tidy. See Creating CHDs from CD-ROMS.
BIOS
The BIOS files needed are: dc_boot.bin, dc_flash.bin. The boot file is often found named something else, such as dc_bios.bin. It must be renamed to dc_boot.bin when placed in the BIOS folder. lr-flycast has support for the Sega Naomi and Atomiswave arcade systems but you will also need the corresponding BIOS from the MAME romset.

Note: If you are having trouble with having to set the date/time every time you load Reicast, see this forum post for a guide on how to replace dc_flash.bin. The MD5 of the dc_flash.bin generated from that guide should be 2f818338f47701c606ade664a3e16a8a
.
Note: As of February 2019, the date/time prompt should appear only the 1st time Reicast is started.
Video Setup Guide
RetroPie 4.0 uses an output resolution independent render resolution of 640x480. Open /home/pi/.reicast/emu.cfg
to modify render resolution.

VMUs
Reicast
VMUs are stored as .BIN files under /home/pi/.reicast/
, and will be automatically created the first time you run Reicast without VMU files.
On occasion, these VMUs do not get formatted quite right during creation, and the Dreamcast can't save or load data from them. They just need to be reformatted -- run the SYSTEMMANAGER
entry in the EmulationStation Dreamcast menu and / or see this post for details.
lr-flycast
VMUs are stored as .BIN files under /home/pi/RetroPie/BIOS/dc/
, and will be automatically created the first time you run lr-flycast.
There is an option for the core to enable per-game
VMU's. This option is recommended if you have several games or a game that takes a large amount of space.
Management
A Dreamcast soft-reset (A+B+X+Y+Start buttons at the same time) at the ROM's title screen will also take you into the Dreamcast BIOS to manage the VMU's. After formatting VMU's, exit the emulator and restart if using Reicast. Pressing 'Play' will cause Reicast to crash.
Controls
Starting with RetroPie 3.3 controls for the Dreamcast Emulator are automatically configured when you configure your controls through emulationstation.Please notice that you may be interested in disabled the input auto config ( described above ) in case of any autoconfig issue.
Controls can be mapped via the /home/pi/.reicast/emu.cfg
file. Make sure that evdev_device_id_1 & evdev_device_id_2 are set to the corresponding controller's /dev/input/event* number you want to use. A -1 means no controller which we will use for player 3 and 4. Then have evdev_mapping_1 & evdev_mapping_2 point to the matching controller mapping configuration files and both can either point to the same file or different files if you want to use 2 different controllers types.
Here is an example of this:
If you want to be able to use 2 controllers at the same time, then you would add this section to the emu.cfg
file:
In more recent builds of reicast, the +Start Reicast script launches a landing page with a game menu with containing a 'settings' button. Controllers can be mapped directly from the settings menu - this creates config files looking like:
In stock configuration, access to this menu is controlled from the D-Pad of a controller with an analog stick. In the case where your controller does not have an analog stick, it may be necessary to connect one in order to access this part of the menu and create mappings for your other controllers.

Some example mappings are provided below for various controllers which can be directly edited from the
Folder listed above.
An example mapping for a PS3 controller is below for reference:

If mapping is not working correctly try changing controller name for:
For Wireless PS3 Controller use:
Replace xx:xx:xx:xx:xx:xx with your own controller mac address
Press ctrl+c to exit- Or map a Quit button (PS) as shown above :D

run in terminal :
Here is a script called 'reicast-joyconfig'run it :
Choose your joystick.Now you can map your buttons.When all is done it outputs the text for making a file in /home/pi/.reicast/mappings
.
It outputs something like this (numbers are in decimals not hexadecimal such as in other contollers' config file):
Dc Bios Bin Dreamcast
Create a file in /home/pi/.reicast/mappings
called controller_Your Gamepad.cfg
and paste the text in this file, then modify the /home/pi/.reicast/emu.cfg
and reference this file in the evdev_mapping_1
(change the number according to the player you want to configure) configuration option.
