What's the problem? Describe what went wrong in few words.
I managed to run out of Wii System Memory in Dolphin and am unable to create new save games.

What did you expect to happen instead?
To have my save data be limited only by my hard drive space.

What steps will reproduce the problem?

1. Fill up the Wii's memory by installing WiiWare/VC games to the Wii Menu
2. Once memory is full, try to make a new save file in any Wii game
3. Check Wii's Data Management settings to see 0 available blocks

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?
4.0-6988
4.0-6732
4.0-430
3.5-2411
3.0-749

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
No.

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
Windows 8.1, 931 GB Hard Drive

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)
I am using NAND dumped from a real Wii, and am on System Menu 513E (4.3U)
I am unable to see if deleting game channels frees up space, as it crashes Dolphin. (Issue #8666)
