 +====== Sega Hikaru ======
 +
 +The Sega Hikaru is an arcade system board released by Sega in 1999. It was an evolution of the [[systems:naomi|NAOMI]] hardware with superior graphics capabilities, featuring two Hitachi SH-4 CPUs and the first arcade platform capable of Phong Shading. Due to its high production cost, Sega abandoned the platform in favor of [[systems:naomi|NAOMI]] and [[systems:naomi2|NAOMI 2]] development, resulting in a very small library of dedicated-cabinet games.
 +
 +This system is only available on **x86_64** builds.

 +==== Quick reference ====
 +
 +  * **Emulators:** [[#demul|Demul]] (default), [[#mame|MAME]], [[#retroarch|RetroArch]]
 +  * **Cores available:** [[#demul_2|Demul]], [[#mame_2|MAME (standalone)]], [[#libretro:_mame|libretro: MAME]]
 +  * **Folder:** ''/userdata/roms/hikaru''
 +  * **Accepted ROM formats:** ''.zip'', ''.7z''
 +
 +===== BIOS =====
 +
 +No BIOS files are required for MAME or lr-mame.
 +
 +For Demul, BIOS files are managed internally by the emulator.
 +
 +===== ROMs =====
 +
 +Place your Sega Hikaru ROMs in ''/userdata/roms/hikaru''.
 +
 +ROMs should be in zipped format compatible with **MAME 0.284** or later.
 +
 +<WRAP center round important>
 +The emulators are still work in progress for Hikaru games, so mileage will vary. Performance depends on your x86_64 system hardware. If you get audio stuttering and slow music, your system is not powerful enough to run this system.

 +
 +===== Emulators =====
 +
 +==== Demul ====
 +
 +[[https://demul.emulation64.com/|Demul]] is a Sega Dreamcast and arcade emulator running under WINE. It is the **default emulator** for Hikaru in Batocera.
 +
 +<WRAP center round important>
 +Your graphics card requires **Vulkan drivers** for Demul to work.
 +</WRAP>
 +
 +=== Demul: First start ===
 +
 +You need to run a ROM at least once **and** be connected to the internet. This creates the directory structure and installs the associated Windows libraries for WINE.
 +
 +It may take some minutes before the game starts on first use — this is normal. Please be patient as it can take up to 2 minutes depending on your internet connection speed.
 +
 +=== Demul: Controllers ===
 +
 +Currently controllers cannot be configured using the desktop app. This is a limitation of the Demul app under WINE but also a known buggy pad plugin, even under Windows. Currently 2 players are mapped using the emulator's default keyboard configuration via evmapy.
 +
 +=== Demul: Service Menu ===
 +
 +A keyboard is required. You can access the Service Menu using **F4** and then use **F2** to navigate with **F4** to select.
 +
 +=== Demul configuration ===
 +
 +^ ES setting name ''batocera.conf key'' ^ Description >> ES option ''key value'' ^
 +| **GAME ASPECT RATIO ''hikaru.demulRatio''** | Set the game aspect ratio.\\ >> Stretch ''0'', 4:3 (Default) ''1'', 16:9 ''2''. |
 +| **VSYNC ''hikaru.demulVSync''** | Fix screen tearing.\\ >> Off ''0'', On ''1''. |
 +
 +=== Demul: Compatible ROMs ===
 +
 +Demul has a specific list of currently compatible ROMs:
 +
 +^ ROM name ^ Game title ^
 +| ''airtrix'' | Air Trix (Rev. A) |
 +| ''airtrixo'' | Air Trix (original) |
 +| ''braveff'' | Brave Firefighters |
 +| ''hikcheck'' | Hikaru Check ROM BD |
 +| ''pharrier'' | Planet Harriers (Rev. A) |
 +| ''swracer'' | Star Wars: Racer Arcade |
 +| ''sgnascar'' | NASCAR Arcade (Rev. A) |
 +| ''sgnascaro'' | NASCAR Arcade (original) |
 +| ''von4'' | Cyber Troopers Virtual-On 4: Force (Rev. E) |
 +
 +==== MAME ====
 +
 +[[https://www.mamedev.org/|MAME]] (standalone) can be used as an alternative emulator for Hikaru games. It supports the full Hikaru ROM set, though emulation accuracy and performance vary per game.
 +
 +==== RetroArch ====
 +
 +[[https://docs.libretro.com/|RetroArch]] with the **libretro: MAME** core is also available.
 +
 +=== RetroArch configuration ===
 +
 +RetroArch offers a **Quick Menu** accessed by pressing ''[HOTKEY]'' + {{:wiki:south.png?nolink&20|South button (B SNES)}} which can be used to alter various things like [[:advanced_retroarch_settings|RetroArch and core options]], and [[:remapping_controls_per_emulator|controller mapping]].
