Apr 11, 2018 How to Burn Dreamcast Games. Three Parts: Preparing to Burn Burning with ImgBurn Playing the Burned Game Community Q&A. If you have an old Dreamcast, you may be able to play burned backup discs on it. This will help keep your original discs in pristine shape, and you can even load homemade games by burning them. A.BIN file is a compiled program for your Sega Dreamcast, it’s those that you can get most of time in packages labelled “plain files”. Scrambled state files are used when the binary is meant to be booted from a CD-ROM, i.e. When the homebrew program is started from the bootstrap, often called IP.BIN.
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 considered experimental at the moment and can be found in the Manage Experimental Packages menu in the RetroPie Setup Script.
ROMS
Accepted File Extensions: .cdi .chd .gdi for Dreamcast ROMs, .zip for Naomi/Atomiswave games.

CHD Archive Usage
Reicast has support for the CHD (V5) archive format.
This format will save space and allow you to keep your Dreamcast ROM folder tidy.
The following archive contains a MAME 0.205 version of CHDMAN and Windows batch files that can be used to quickly convert your Dreamcast games to CHD (V5): Download
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

.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.Dreamcast Games .cdi Files

VMUs
VMUs are stored as .BIN files under
/home/pi/.reicast/
, and will be automatically created the first time you run Reicast without VMU files.Dreamcast Cdi Download
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.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. 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:An example mapping for a PS3 controller is below for reference:
PlayStation 3 Controller
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
