Also, the first page needs to be updated. There is a new version of brick-blocker that works now with the DVD9 iso, and it's the preferred method to use, rather than wii-update-remover 1.0.
Please, note that, as "weird" as it may sound, 99% of all the problems some people are having with this game is that their burners/media combination don't produce DL disc that the wii likes.
It is VERY encouraged that you try at least two different brands of quality media on your burner. If it fails, try REALLY HARD to find another burner (from a friend or something) where you can make a copy of your DL disc, also in at least two different brands of media. I won't even go into trying different speeds, as only 2,4X (for old media/and-or/old burners) and 4X (for new media on new burners) are recommended. Given a choice between DVD-R DL and DVD+R DL, choose the later. They both work for some people, but most people with problems still not solved have only tried -R media.
After you tried all this, you may start to suspect something else wrong.
Please note that even the dumper of this game got it to play fine on you d2ckey, as has many other people.
Please note that, due to firmware design, all wiikey 1.9g wii's are running at 3X reading speed regardless of the configuration settings (it ignores them, unlike 1.9b firmware revision). At low reading speeds, the wii may have a bit easier time reading "bad" dvd9 burns. D2Ckey and other chips don't have this "limitation" and run at 6X reading speed. Better quality burns are necessary for those wii.
Please note that not all wii's are able to read discs as well. A marginal DL burn may work on one wii and may not work on others. Here are two articles describing how SOME wiis may have problems reading dual layer discs (while other don't).
IGN: Nintendo to Clean Japanese Wiis Over Smash Bros. Errors
Nintendo blames this on "dirty lenses", but the truth is that the laser in some wii's is tuned a bit too low for reliable dual layer operation. Here is a link to an article about it from MONTHS AGO (this is not a "new" problem, it's just the first time a dual layer wii game's been released)
http://www.cyclopswiz.com/ (scroll down just a bit, to where it says "upgrade 3.5")
This is even worse on RECORDEABLE DL media, as it has MUCH lower reflectivity than pressed ORIGINAL media. To try to avoid problems also, Nintendo used for this game a top quality GOLD layer press disc, that has even higher reflectivity than the silver discs. The highest in the industry.
Lots of people had a #001 error when trying to run this game in DL with a wiikey. It was finally figured to be bad media for most of them. You can follow their progress in this thread:

Seems that the #001 error may be the wiikey "equivalent" to a blank screen.
So please, again, before you bang your head agains a wall, try to get hold of a different burner and try once more with good media. There is no one recommendation of what "good media is". The only one recognized as truly good is a Verbatim DVD+R DL that has written in the label 2.4x-6x (sometimes only says 2,4x on older stock) and that says made in singapore. Please note that if it says made in india is just as crappy as any other, so avoid. The Verbatim labeled 8X is a DIFFERENT media, but also known to be good in new burners, but not as good as the other. Again, given the choice, use +R instead of -R. Try brands like Sony, TDK, Kodak, Fuji and other japanese brands, like Taiyo Yuden, etc. Some people report good results with the taiwanese-made ridiscs. Lots of people with problems with brands like Imation, playo, princo ... But they do work well for some people and the other way around, so you have to try what your burner prefers.
For those that want to take a look at what those Verbatim it looks like, someone in another thread made wrote this link:
http://svp.co.uk/product/verbatim_(24x)_do..._r_(95166)_3718
They are sold in may different types of packaging, with different labels and different quantities, all having in common that the mention the 2,4x speed. The main problem being that they are often "mixed-up" with the made in India ones, which is ironic, because the singapores are about the best dual media ever produced and the india are well well below average, almost worthless.
You can see in the description from the store linked above that they are aware that only the ones made in singapore are the specific variation of the metal-azo formulation that has been known to give the best results across the largest number of burners at somewhat slow speeds (2.4x to 6x).
Also, as a general rule, burners older than about 2 years do a crappy job on dual layers, as do laptop burners older than about 1 year. There are exceptions, of course, specially on some Pioneers that did very good on DL. If you'd like to get a new burner, there are plenty for around $40 and virtually all modern ones do a decent job on DL recording. Some models by Pioneer (but not other models) and some Samsungs (but not all) have very favourable reviews.
