I had a dozen Wiiware titles that I kept on my SD card for space reasons. Obviously, when I transferred my data to the Wii U these wouldn't fit and I was told I'd have to download them again later.

Today, I thought I'd finally get around to redownloading them and putting them back on the SD card, so I loaded it up. My first surprise was that they're all still there! Then I found out they wouldn't play. So I tried downloading them to the SD card - it wouldn't let me because they were already there... So I went into data management and deleted a game. It let me download it but I still couldn't play it. Wondering if this was because it thought the SD card was locked to another console I put it in my PC and formatted it (that would be a pain for someone with hundreds of titles but I only have a dozen on there) then put it back in the Wii and downloaded a game again. It still won't play.

Has anyone else had this problem? Is it possible to play games from the SD card menu in the Wii emulator on the Wii U?

I can't say I've tried it myself because I refuse to do the SD card mambo when I haven't used any of my Wii U internal storage for anything else so I should be able to use it for all my WiiWare VC content.

All I can suggest is trying a different SD card or seeing if you get different results when copying the game from SD into the Wii Channel menu and then report it to Nintendo. You have installed the Wii U update presumably?

I think there's something with the emulator that prevents you doing that - I had the same idea but when I went to download the games to system memory it told me there wasn't enough space, with the familiar Wii "blocks" cited. It's almost like they're emulating the platform in its entirety, including a Wii allocated memory.

I have no retail downloads at present - just Trine 2 and the Rayman Demo, so I know there's plenty of space.

Did you delete all the games in one go? I suggest deleting ALL content off the memory card, then redownloading a couple games to see if it works.

Yep, as I said, I formatted it in my PC, then inserted it and downloaded again.

I don't know what to say. You didn't need to format it though. When I transferred, I just went into the SD card data and deleted everything manually, then went in the shop to redownload everything. Are you sure you watched Pikmin transfer your console, and it saying 100% complete?

Yep, all that worked fine and all of the Virtual Console games on my main Wii menu work fine too. Just this issue in running things (specifically I'm talking about Tetris Party here, maybe I should try one or two of my other Wiiware games too) from the SD card.

I play games from the sd menu in the wii emulation mode no problem

Hmmm... Well, tomorrow morning I have to see if I have the same problem with other games and then maybe buy another SD card to try.

Yes try another card. i use a micro sd in an adaptor and it all works fine.

OK, solved the problem. The problem being that I was acting the idiot. I'd forgotten that when I transferred to the Wii U I copied an extra game over to the Wii system memory (because I could). Moving that back to the SD card enables me to launch things from the SD card menu again.

I really hope Nintendo release a system update that incorporates Wii software fully. I didn't mind too much to begin with but it's a pain to have to launch a separate menu to play a disc game on a new system (even if it is a disc from an old system) and it's a pain to have to go from the Wii U menu to the Wii menu to the Wii SD card menu to play some Wiiware titles.

Yeah that's right you need to have an amount of space free in the "system" to accommodate the largest game on SD you want to play.
