RVT-R Reader
A RVT-R Reader is a development system that highly resembles a retail unit, but has a green cover in front.
Revolution OS identifies this as Emulation platform (10000002) with 88MB of memory.
System Menu
System Menu can be installed by the Wii Menu Changer disc, which depending on its version can provide 1.0 to 4.3 menu in every region. Just like NDEV, the System Menu is optional ; when not installed, the reader boots the DEVKIT menu instead.
All RVT-R Readers Wii menu versions/regions seem to use development version v2, regardless of their retail counterpart.
IOSes
IOS4v3, IOS9v516, IOS10v518, IOS11v10, IOS12v6, IOS13v10, IOS14v257, IOS17v512, and IOS21v514 were found on both 1.0U and 2.2E devices. This suggests that a common set of IOSes may have been preinstalled on the readers at the factory. However, depending on the System Menu, Wii Menu Changer disc also installs several IOSes.
The 1.0U device also included IOS30v1039, likely because System Menu 3 had been installed at some point. The 2.2E unit additionally contained IOS22v772, IOS28v1288, IOS33v1040, IOS35v1040, IOS53v4113, and IOS56v5405, probably as a result of disc updates.
The DEVKIT menu features a "Firmware" submenu that lists the installed IOSes (referred to as "firmware"). It is noteworthy that IOS4v3 will not appear in this list even when it is installed.
Titles
Two additionnal channels, with entries in /meta, are installed alongside the System Menu : a disc check tool (0144434b.dck) and a tool to uninstall the System Menu (01574d55.wmu).
1.0U has EULA in two versions : a Japan version and a U.S. version. 2.2E has an European version. Regardless of the region, EULA has entries in /meta, being the only known instance of files in /meta/00010008. The first one was built by @SASAKIT-COM2, the second one by kitamurs@KITAMU.
Content IDs appear to be allocated randomly, resulting in content IDs like the one for IOS4v1. However, there is probably a pattern, since titles from different regions seem to share content IDs.
Disc format
RVT-R discs can be written using an RVT-R Writer. The structure of the discs themselves is not known. It may be possible to recover this structure from the RVT-R Reader drive firmware.
Blank discs can be identified by the data side being in a more blue hue. CleanRip is able to dump those discs ; however, attempting to dump a blank disc with CleanRip yields glitchy chars on the screen, and the disc does not dump.
Differences with homebrew
Latest version of the HackMii Installer is unable to run due to the ES_GetTicketViews hack only working on newer IOSes, and possibly timing issues in older IOSes; however, it appears to reload between IOSes without issues.
