Issue in latest v0.9.6 revisions

I see one clue to why it happens:

For two of the games not shown with extension, the removed extension is not the only difference between the shown title and the file name.
This makes it clear that the titles are either extracted from the CSO files as-is, or derived from the game IDs extracted from the CSO files.

For either case this means that there is for those games no direct relation between the file name string and the title string shown.
But for cases where the extraction of title or game ID from the CSO file fails, PPSSPP probably falls back on showing the file name unchanged.

So the real question here should be: Why did PPSSP fail to identify the standard title of this game (by either method) ?
One guess is that there could be a problem with the CSO decompression used in scanning for game title/ID.
