 ====== Cave CV1000 ====== ====== 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.
  
-The [[https://wiki.arcadeotaku.com/w/CAVE_CV1000|Cave CV1000]] is the series of arcade boards Cave released all its arcade games on between 2004 to 2012. +This system is only available on **x86_64** builds.
- +
-First the CV1000-B was produced, featuring a Hitachi SH-3 CPU (hence why it may sometimes to be referred to as the "Cave SH-3"); its first title being Mushihimesama. In 2008, the CV1000-D was produced which featured additional RAM; its first title being DoDonPachi DaiFukkatsu. +
- +
-A list of its games can be found on System 16's hardware pages for [[https://www.system16.com/hardware.php?id=868|CAVE CV1000-B]] and [[https://www.system16.com/hardware.php?id=961|CAVE CV1000-D]]. +
- +
-This system scrapes metadata for the "cave3rd, arcade" group(s) and loads the ''cave3rd'' set from the currently selected theme, if available.+

- +[[https://demul.emulation64.com/|Demul]] is a Sega Dreamcast and arcade emulator running under WINE.
-After loading a Cave CV1000 ROM for the first time, Batocera will download and install the appropriate files. This process takes a few minutes up to (a long time) depending on your internet speed. There is no progress bar. +

-While running a game, press ''[F4]'' to access the service menu for that title. This menu contains different options for each game, and saves their configuration independently.+=== 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.
  
-Repeatedly press ''[F2]'' to navigate the menu, and press ''[F4]'' to confirm.+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.
  
-===== Controls =====+=== 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.

-Therefore controller 1's start button is 0100013b in hex or 16777531 in decimal. +
