You are probably using the v0.1 host. This bug is fixed in v0.2.When trying to dump Lego City Undercover meta folder I get this
Code:./titledumper /vol/meta test Title Dumper by Dimok Waiting for WiiU connection... Client 0 connected Client 1 connected Create path: test/vol/meta Open file: test/vol/meta/bootDrcTex.tga Failed to open: test/vol/meta/bootDrcTex.tga pFile == NULL on close ...
You can also use
./titledumper /vol/meta ./test
which circumvents this problem.
