I'm using 3.1E on a PAL system, I had done the 15% trick for the NTSC-J version of SSBX.
I have just used Trucha Signer to replace the disc's __update.inf with the one provided in the post and that's all the modification I did... I'll let the update run fully and let you know how it goes.
By the way, you can extract the rest of the key files just fine from this US SSBX dump, like the tutorial says.
If someone needs a mirror of the replacement INF file, I've uploaded it on Rapidshare and Megaupload for everyone...
