====== Cave CV1000 ======
The Cave CV1000 (also known as Cave SH-3) is an arcade system board used by [[https://en.wikipedia.org/wiki/Cave_(company)|Cave]] for all their arcade releases from 2004 to 2012, with the exception of Deathsmiles II. Powered by a Hitachi SH-3 CPU, the platform is famous for its legendary bullet hell (danmaku) shoot-em-ups including the Dodonpachi, Mushihime-sama and Espgaluda series. The board has three revisions: CV1000-B (early), CV1000-B (later) and CV1000-D.

This system is only available on **x86_64** builds.

<WRAP center round important>
The emulators are still work in progress for Cave CV1000 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 =====
==== RetroArch ====
[[https://docs.libretro.com/|RetroArch]] with the **libretro: MAME** core is the **default emulator** for Cave CV1000 in Batocera.

=== 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]].

==== MAME ====
[[https://www.mamedev.org/|MAME]] (standalone) can be used as an alternative emulator for Cave CV1000 games. It supports the full Cave CV1000 ROM set.

==== Demul ====
[[https://demul.emulation64.com/|Demul]] is a Sega Dreamcast and arcade emulator running under WINE.

<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 ''cave3rd.demulRatio''** | Set the game aspect ratio.\\ >> Stretch ''0'', 4:3 (Default) ''1'', 16:9 ''2''. |
| **VSYNC ''cave3rd.demulVSync''** | Fix screen tearing.\\ >> Off ''0'', On ''1''. |
