Installation of Dreamcast games
1- Dreamcast games can come in many different formats; There is GDI format for full game copy, CDI format or you can compress your GDI files in Chud format. If you do this, the games will take up less than 1.1 GB of storage space. They are compressed and take up less space.
2- For multi-disc games for these games you need to create an M3U file in this game folder and then the game will appear as a single entry in Retroarch and you can easily swap discs between them.
3- To create an M3U file, first create a text file in the game folder; the filename must be the name of the game. At the same time, you must also specify the file extension. If you can't see the file extensions, go to Show and for the expanded list, make sure filename extensions are enabled.
Open the file you just created and copy the file associations, ie copy and paste the two file names and their extensions into the text file. If your games are in CDI format, copy the CDI format, and if they are in GDI format, you need to copy the GDI file. After copying all disk names into the text file, save this text file and rename the extension from .txt to .m3u. You need to do the same process for all Dreamcast games.
4- Create a games folder inside the Retroarch folder and paste all games into this folder.
5- Now download the Dreamcast BIOS file. Once the file is downloaded you need to paste it into the Retroarch folder. Rename this file to DC_boot.bin and paste it into the Retroarch system folder. Open the Retroarch folder, go to the system folder, create a Dc folder here and paste the BIOS file.
Back arch settings
1- Now launch Retroarch and once the main menu is open go to the online updater and select the main downloader. Scroll up or down to find the Sega section, select Sega Dreamcast/Naomi (Flycast) and click to download.
2- Then go back to the main menu and select Load Content to load Dreamcast content. Once you've selected this, you need to go to the directory where all of your Dreamcast games are installed. Then select the game and core and the game will begin.
3- To create a games list, go to the main menu, click on the Show desktop menu or press F5 on the keyboard. When the desktop menu is open, you will see the content browser on the left side of the screen. Right click on it, select the new playlist and the playlist name should be Sega -Dreamcast. Then, press ENTER. A new playlist will be created on the left.
4- Right click on the right side and select Add Folder. Then go to where your games are installed, select the games folder and click the Select Folder button at the bottom.
5- Configure the core for Flycast, configure the database for Sega Dreamcast and click OK. Now all your games will be added to the playlist.
6- After creating your playlist, go back to Retroarch in the main menu and click on the Reset Retroarch button. It will help you view your game playlist on the left side.
7- If you want to play it now, select the game from the game playlist you just added and click the Play button on the next page.
driver settings
Go to the Controller Settings option, select the Port 1 control here and see what controls are mapped to your Dreamcast controllers. You can customize each of your controllers for each game.
main options
1- After that go back to Core option. The first option is the BIOS selection that you added during the initial setup and is selected here.
If you don't have a Dreamcast BIOS file, there is a built-in high-level emulation BIOS file, but its compatibility may be better than the official one, so you need to download the BIOS file first.
2- Then go to the System tab; The first option is the region. Set it as your default region and the next option is the language; You need to set it according to your native language. The next option is to use the Hle BIOS file. If an up-to-date BIOS file is present, you can force the use of a high-level emulation BIOS file.
3- The next option is to boot directly into the Dreamcast BIOS file. So if you want to boot into the Dreamcast BIOS located in the Retroarch system folder, you can enable this option.
video settings
4- After that, go back to the Video tab and select the internal resolution; You should set this to your monitor's native resolution.
5- The next option is the cable type, which defaults to normal composite cable, which works in most cases. Some games will only work if you set this to RGB or VGA.
6- Then go to Transmission Standard and set between NTSC and Friend. You must keep the screen orientation in landscape mode.
7- The next option is Alpha Sort, which defaults to Triangle and is the most compatible and accurate option. If you have a faster CPU you can tune it pixel by pixel which is more accurate and solves layering issues, or if you have a slower computer you can tune it by track.
8- The next option is the Stack Pixel Buffer Size, which is set to 512 megabytes by default. Set the maximum number of transparent layers to 32. With a powerful computer, you can increase this for better accuracy.
9- After that set Enable RTT to ON and keep Mipmapping, Fog effects and Volume modifier to ON. Set the Anisotropic Filtering to 4, but if you want more smoothing of your textures from different angles, you can increase it to 16. Leave the texture filtering option as the default.
The next option is to toggle delay frames. If you are using a faster computer, enabling this option may help with some shaky videos.
10- The next option is to detect framerate changes, so this can be useful for games with locked framerates around the 30 or 20 FPS mark, but if your game has an unlocked framerate, you should turn it off.
11- Go to the Power VR 2 Post Processing Filter and set it to ON as this makes it slightly more accurate than an original Dreamcast video output. After that, leave Texture Enhancement (xBRZ) OFF.
12- The last option is native depth interpolation. So if you are using an AMD GPU, enable this option, it can also be useful for integrated Intel GPUs. If you are using Nvidia, turn this off.
13- Then go back and set Performance to Threaded Rendering. If you are using a low-end CPU, set it to automatically skip frames.
14- Then go back and select Inner Frame Blending and rotate it. It's the spirit of old CRTs that's better suited to Dreamcast emulation.
15- Select controller cheats as this is required to use things like Robotron 2048. If you want to use a single controller for both joysticks, you can switch ports depending on whether you want the game to be on the right or left port for the controllers, or rotate the default.
16- Now choose the sensitivity of the digital joystick as by default it is set to Automatic and it works in most cases. However, you can adjust the sensitivity to match your base game.
17- Next, select the Analog Stick Sensitivity and set it to Linear. You can also set it to do a square test as it depends on the base game. You need to check which one responds best to your particular game.
18- Then select Analog Joystick Deadzones and you should adjust this deadzone according to your specific controller.
19- Finally select Visual Storage Unit; The first option is the vmus game. It is recommended to enable this option for at least one A1 vmu so you never have to worry about running out of safe storage space. But you can still share saves between different memory cards for different games using the other three ports.
You can also view your VMU on the screen. You can choose the screen position and size to be at least 2x so it can be displayed on your screen. Then you can choose the colors and the opacity, so it's not transparent now. You must set it less than 100 to make it transparent.
20- If there are some options that you want to set for certain games but not for other games, go to Manage Main Options and save them as a game options file. This is the only way to apply to a specific game setting.
Shader
Shaders are extensive and you can give your games a fun look depending on which shaders you have chosen. Open the Shaders tab and enable Video Shaders. You need to make sure you download them from the central updater.
