Crash on Wii when adding/editing games after a certain scummvm.ini file size or game count

ScummVM version: 2.7
OS Version: Wii 4.3U

Details
Attempting to add or edit a game with a large number of games already configured causes a crash.

To reproduce
To simplify reproduction I made several different ScummVM apps configured with 100, 200, 300, 400, and 500 games. You can grab either of the attachments—one for USB devices and one for SD cards—and unzip to the apps dir of your storage device. In my testing the crash started happening consistently with 300 and greater.

If you don't want to trust my zips you can instead copy the scummvm.ini files from the configurations—and optionally meta.xml to make it easier to identify on the Wii—over to an existing ScummVM app dir.
