I don't know if this info is of interest to anyone, but here goes.
My Wii is a very early unit, maybe 3 months after the Wii's launch. Out of the box I installed Wiikey v1 in it which was flashed to FW 1.9s when SSBB came out. That's it as far as mods go, just the Wiikey, no other soft mods of any kind. Wii FW stayed at 3.2U ever since.
So with NSMB finally there's a game that interests me. Went to a few stores yesterday, no one will sell the game. Checked out Wii Sports Resort at Toys R Us and bought a copy. With the original retail disc, it updated my Wii to 3.4U. I tested the game, no problem. Tested all my backup DVDs, all played fine. Then I dumped Resort, burned at 8x, the backup plays perfect. Away from my kids I put the original DVD.
Just now I came back from Toys R Us, bought NSMB. Funny thing with this game. It prompted me to update, no surprise there, and I let it. Went relative quickly, maybe a minute. Now my Wii is at 4.1U. Just to make sure, I tested my Wii Resort backup. Works fine. I reinsert the original NSMB, it prompted another update. WTF? I ejected the disc and reinserted it. This time it said the disc (original disc no less) cannot be read. Double WTF?? Ejected it and put back the Resort backup, played fine.
Rebooted and booted NSMB, it prompts for a second update. I let it. This time it took much longer, like when I updated 3.2U to 3.4U from the Resort retail disc. About 3-4 minutes. It finished its thing and reboots. I check Wii settings, still at 4.1U firmware. What was that second update about?!
Checked my Wii Resort backup, still works. Rebooted with my retail NSMB disc, playing fine so far.
So bottomline, the original USA retail disc works fine on Wiikey'ed Wiis.
I'll dump the game shortly and see if it works.
