Their intended purpose is to read the proprietary [[NROM]] format, but this is not all they can be used for. This drive is interfaced with via the DI (Drive Interface) in the [[GameCube Hardware/Flipper\|Flipper]] and [[Wii Hardware/Hollywood\|Hollywood]] SoCs.

	== ~~Compatibility~~ ==		== Non-NROM media support ==
			In early model Wiis (pre-2008), this drive is capable of reading burned DVD-R or pressed DVD-ROM discs, through special "DVD video" commands, blocked from being sent to the drive via an <code>HW_COMPAT</code> bit normally, but they can be enabled by setting it. Later drive models removed this functionality, regardless of whether commands are permitted to be sent according to the SoC. All GameCube drives can have their firmware patched via software to support reading DVD-R/DVD-ROM.

The [[Wii]] contains a DVD optical disc drive. In early model Wiis (pre-2008), this drive is capable of reading burned DVD-R discs, through a hidden "DVD video" mode that the drive can be set to. Later models removed this functionality. It is interfaced with via the DI (Drive Interface) in the [[Hollywood]] chipset.

== Compatibility with Wii-Linux ==
There is a driver in [[Wii-Linux]] known as <code>rvl-di</code> (file path: <code>drivers/block/rvl-di.c</code>) for interfacing with the DVD drive. Older versions of Wii-Linux supported the DVD drive, however support has heavily deteriorated over the years:

* 3.15.10 (stable-v3.x): Full support
* 4.3.6 (experimental-v4.x): Hang trying to read data from the disc.
* 4.4.302-cip80: Can't read any drive response data (even metadata).
* 4.19 (possibly older?): can't even send basic commands to the drive, like a drive reset.

== Notes ==
[[NetBSD]] has a functional driver for the Wii's DVD drive.
