A fork of a fork of a fork… this is an identical version of standalone Flycast but inside of a libretro core, maintained by the same dev as standalone, Flyinghead. Makes use of RetroArch's features.

Standardized features for this core: atomiswave.autosave, atomiswave.use_guns, atomiswave.cheevos

ES setting name batocera.conf_key	Description ⇒ ES option key_value
Settings that apply to all systems this core supports
SYNCHRONOUS RENDERING global.reicast_synchronous_rendering	When threaded rendering is on (on by default), waits for the GPU to finish rendering the frame before dropping the current one. This can avoid certain emulation issues (flashing screens, glitchy video). Significant performance cost. Recommended “Off” for most games as they don't experience issues (or you have a weak machine), “On” if the game has these particular issues. ⇒ Off disabled, On enabled.
RENDERING RESOLUTION global.reicast_internal_resolution	Enhancement. Increases the rendering resolution. Makes 3D objects clearer. Significant performance cost. Use 640×480 for native. Absurdly high values can degrade image quality (pixels beginning to shimmer). ⇒ 1x (640×480) 640×480, 1.25x (800×600) 800×600, 1.5x (960×720) 960×720, 1.6x (1024×768) 1024×768, 2x (1280×960) 1280×960, 2.25x (1440×1080) 1440×1080, 2.5x (1600×1200) 1600×1200, 3x (1920×1440) 1920×1440, 4x (2560×1920) 2560×1920, 5x (3200×2400) 3200×2400, 6x (3840×2880) 3840×2880, 7x (4480×3360) 4480×3360, 8x (5120×3840) 5120×3840, 9x (5760×4320) 5760×4320, 10x (6400×4800) 6400×4800, 11x (7040×5280) 7040×5280, 12x (7680×5760) 7680×5760.
TARGET COLOR FOR PLAYER 1. global.reicast_lightgun1_crosshair	⇒ Red Red, Blue Blue, Green Green, White White, Disabled disabled.
TARGET COLOR FOR PLAYER 2. global.reicast_lightgun2_crosshair	⇒ Red Red, Blue Blue, Green Green, White White, Disabled disabled.
TARGET COLOR FOR PLAYER 3. global.reicast_lightgun3_crosshair	⇒ Red Red, Blue Blue, Green Green, White White, Disabled disabled.
TARGET COLOR FOR PLAYER 4. global.reicast_lightgun4_crosshair	⇒ Red Red, Blue Blue, Green Green, White White, Disabled disabled.
TEXTURE MIP-MAPPING (BLUR) global.reicast_mipmapping	Enables mip-mapping to smooth out textures on distant 3D objects based on distance and angle. Dreamcast games natively utilized mipmapping to get extra performance out of the hardware, but the extra bluriness from doing this is more apparent on modern, higher fidelity screens. Has a minimal performance cost. enabled should be used in conjunction with anisotropic filtering to mitigate bluriness. Some users may prefer the 'sharpness' of disabled better. ⇒ Off disabled, On enabled.
ANISOTROPIC FILTERING global.reicast_anisotropic_filtering	Enables anisotropic filtering to enhance perspective textures. Dramatically improves the clarity of textures on distant 3D objects when mip-mapping is turned on, especially at higher internal resolutions. Test Drive: Le Mans is the only Dreamcast game that natively utilizes this. Has a small performance cost. Generally safe to use 16x when mip-mapping is also enabled, leave on “Off” otherwise. ⇒ Off False, 2x 2, 4x 4, 8x 8, 16x 16.
TEXTURE UPSCALING (XBRZ) global.reicast_texupscale	Enhancement. Applies xBRZ upscaling to textures to improve their clarity. Improvements are subjective. ⇒ Off False, 2x 2x, 4x 4x, 6x 6x.
RENDER TO TEXTURE UPSCALING global.reicast_render_to_texture_upscaling	( this setting is now missing?) Enhancement. Some 3D games would capture the screen output and render it as a 2D texture (eg. pause menu in Crazy Taxi and Dead or Alive), being unaffected by reicast_internal_resolution. This setting multiplies the resolution of that capture. Example here. “Off” for native, “4x” for close-to 1080p rendering (only useful if also upscaling the internal resolution). ⇒ Off 1x, 2x 2x, 3x 3x, 4x 4x, 8x 8x.
FRAMESKIP global.reicast_frame_skipping	Skip frames to improve performance, at the cost of choppy motion. Higher values can cause motion sickness if used for extended periods. Should only be turned up on weak hardware and if immune to motion sickness. ⇒ Off disabled, 1 1, 2 2, 3 3, 4 4, 5 5, 6 6.
FORCE WINDOWS CE MODE global.reicast_force_wince	Some Dreamcast games (marked “Powered by Microsoft Windows CE” on the box, eg. Sega Rally 2) utilized the MMU Windows Compact Edition API on the Dreamcast to run. Batocera should automatically detect this but in case it doesn't you can manually override it here. Significant performance cost. ⇒ Off disabled, On enabled.
WIDESCREEN CHEAT (PRIORITY) global.reicast_widescreen_cheats	Enhancement. Flycast has a database of cheats that can enable widescreen support in certain games, rendering them in anamorphic widescreen without changing the internal resolution. Some games also natively support widescreen in their in-game options. A 16/9 ratio must be used and bezels must be disabled. ⇒ Off disabled, On enabled.
WIDESCREEN HACK global.reicast_widescreen_hack	Enhancement. Changes the internal resolution to a widescreen ratio (eg. 640×480 becomes 853×480). Somewhat glitchy. Some games also natively support widescreen in their in-game options. A 16/9 ratio must be used and bezels must be disabled. ⇒ Off disabled, On enabled.
CONTROLLER 1 TYPE global.controller1_dc	Chooses the controller plugged into port 1. ⇒ Gamepad 1, Keyboard 3, Mouse 2, Light Gun 4.
CONTROLLER 2 TYPE global.controller2_dc	Same as above for port 2. ⇒ Gamepad 1, Keyboard 3, Mouse 2, Light Gun 4.
CONTROLLER 3 TYPE global.controller3_dc	Same as above for port 3. ⇒ Gamepad 1, Keyboard 3, Mouse 2, Light Gun 4.
CONTROLLER 4 TYPE global.controller4_dc	Same as above for port 4. ⇒ Gamepad 1, Keyboard 3, Mouse 2, Light Gun 4.
Settings specific to atomiswave
SCREEN ORIENTATION atomiswave.screen_rotation_atomiswave	Rotate screen for some arcade games ⇒ Horizontal horizontal, Vertical vertical.

All other settings can be configured from RetroArch's Quick Menu → Options ([HOTKEY] + ).

Flycast is a fork of Reicast (which itself is a fork of nullDC). A highly compatible and accurate standalone Dreamcast emulator.

Flycast can also be used to run Atomiswave arcade games due to being nearly identical hardware.

Standardized features available to all cores of this emulator: atomiswave.videomode, atomiswave.videomode, atomiswave.bezel, atomiswave.bezel_stretch, atomiswave.hud, atomiswave.hud_corner, atomiswave.bezel.tattoo, atomiswave.bezel.tattoo_corner, atomiswave.bezel.tattoo_file, atomiswave.bezel.resize_tattoo

All other configuration must be done via the flycast-config in the Applications folder ([F1] on the systems screen).

Here are the default Atomiswave's controls shown on a Batocera Retropad:
