Instructional DVD
The Super Mario Galaxy 2 Instructional Discs are standard DVD-ROM discs that came separately with some European and Japanese region Super Mario Galaxy 2 disc purchases (none were ever issued or available for CHN, KOR, TWN, USA). Due to the region protections, standard American DVD players are unable to play these discs. However, their disc images/ISOs can be dumped (currently only tested) on Linux (dumps of which will soon be available for preservation purposes).
These discs feature 24-minute-long, 9:16, MPEG2 videos showing some of the game's basic mechanics (how to navigate the various player controls, mostly).
Interestingly, it can be seen in text on the inside of the disc cases, explicitly stated, that the videos recorded for these discs were played on development builds of Super Mario Galaxy 2 (for each region, respectively). What precisely are the build dates or time frames, we are unsure about. However, given that these discs were released alongside these Super Mario Galaxy 2 regions, they must be very close to the retail builds. In observations from various clips from both discs, 3 main cutaways of debug capabilities of these builds are the supposed ability to silence or change stage BGM, a StageSelectMenu of some kind (as seen from some stages being played on 0 Stars counted) and perhaps a PAD recorder for maintaining consistency in player movements between language sections.
Secondly, it can also be seen that these discs have been assigned with an ID starter of 9B4, instead of the retail SB4; making it one of the few non-Wii compatible discs to be assigned with a Wii-disc-like ID (and ring code).
The following Gallery currently only contains image scans (made by a Canon printer) of the EU version of these discs.
