The '''''CAVE CV1000''''' is the third generation arcade hardware from [[Cave]]. The ''CAVE CV1000'' hardware was used in all arcade games released by Cave from [[Mushihimesama]] in 2004 through [[DoDonPachi SaiDaiOuJou]] in 2012, with the exception of [[Deathsmiles II]]. The ''CAVE CV1000'' is also known as Cave SH-3 hardware, due to the arcade system being powered by a Hitachi SH-3 CPU. There were two versions of the ''CAVE CV1000'': the CV1000-B, which is the original PCB first released with Mushihimesama, and the CV1000-D with more RAM, first released with [[DoDonPachi DaiFukkatsu]].

With the release of DoDonPachi SaiDaiOuJou, Cave will no longer produce games for the CAVE CV1000. Future releases will be for the [[NESiCA x Live]] system, which requires a [[Taito Type X²]] or [[Taito Type X³]].<ref>[http://www.cave-stg.com/forum/index.php?topic=1615.0 Cave starts making NESiCA arcade games]</ref>

== CAVE CV1000 Technical Information ==
*CPU: Hitachi SH-3 SuperH family 32-bit RISC CPU clocked at 133 MHz
*GPU: Altera Cyclone EP1C12 FPGA
*APU: Yamaha YMZ770C-F

== Reinitialization ==
CAVE CV1000 PCBs are able to be reinitialized to factory default settings. This will also reset saved high scores on games that have no reset high score function, like Mushihimesama and [[Espgaluda II]].

To reinitialize a PCB, you must:
*Remove the battery
*If using U10, short Pin 9 (DO) a GND. If using U13, short the fourth pin from the right on the bottom row to a GND.<ref>[http://shmups.system11.org/viewtopic.php?p=746448#p746448 shmups.system11.org • View topic - Cave SH3 games that have no hiscore table erase.]</ref> You only need to short one of the two pins, not both.
*While shorted, power on the PCB until the EEPROM test

It should be noted that this is done at your own risk and no one can be held responsible if you irreversibly damage your PCB in the process of performing the reinitialization.
