Recently, we gave word that a Wii firmware update issued late last month could possibly block Datel’s region-bypassing FreeLoader disc, if the Wii System Menu was updated to use IOS37 by an upcoming game disc or supplemental update.

Turns out that Mario Kart Wii may be the first game title to block the device, even though early reports have indicated that the IOS37 firmware is not included on the disc. After the jump is a copy of the letter Play-Asia sent to purchasers of the Japanese version of Mario Kart Wii, notifying them that the title does not work with Datel’s FreeLoader:

This is an important e-mail update regarding your pending preorder Mario Kart Wii (w/ Wii Handle) (Nintendo™ Wii Japan, NTSC J)

We received the first small delivery today for testing and unfortunately we have to inform you, that the game is not compatible with the Datel Freeloader (US and PAL Version).

In case that this affects your preorder, please contact our customer service as soon as possible to amend/cancel your order, as otherwise we will ship your order within the next 48 hours.

If you own a Japanese Wii and you do not want to change your orders, you do not have to reply to this email.

Once again thanks for shopping with us and sorry for the inconvenience caused.

Ouch. If true, this is not good news for Datel or owners of the FreeLoader.
