The '''Pre-production boards''' are a series of prototype Wii boards, their existence only being known due to SDK text strings and references in [[all.ini]]. SDK references define each of these boards as a console type; see [[OSGetConsoleType]]. Oddly, PP0 is not mentioned in SDK strings compiled into applications, and PP3 is only mentioned in all.ini.

The '''Pre-Production Boards''' (official capitalization "Pre-production boards") are a series of prototype Wii boards, their existence only being known due to SDK text strings and references in [[all.ini]]. SDK references define each of these boards as a console type; see [[OSGetConsoleType]]. Oddly, PP0 is not mentioned in SDK strings compiled into applications, and PP3 is only mentioned in the list of factory titles present in all.ini and [[RVL_DIAG]] as part of the description for the swupDiag ([[SWUpdate]]) program, which is apparently intended for PP3 boards.

As the swupDiag application present in [[RVL_DIAG]] is apparently intended for PP3 boards, and is compatible with Dolphin, it is known that the PP3 board is similar to retail hardware.

There is also a 'Pre-Product 4' [[RVT-R Reader]] unit which is seemingly post-final and has no apparent pre-production features; it is unknown why it is labeled as such.

== Correspondence to NDEV versions ==

Disassembling [[OSGetConsoleType]] reveals that each of these boards from PP0 to PP2-2 corresponds to an [[NDEV]] version, with PP0 being NDEV 1.0 and PP2-2 being NDEV2.0. These boards were considered the retail equivalent to these NDEV versions, using the same [[Hollywood]] revision. It is possible that the [[RVT-R Reader]] for [[E3 2006]] used one of these boards.
