Here the tool 1.0:

It's written in C#.NET 4.0, so you will need the .NET Framework 4.0.
It should work for *.txtd and eboot.bin (decrypted), i did not test the pBin support, but it should also work.
For pBin, use Tools->Unpack pBin and then open the extracted "*_001.bin" with File->Open bin.
Currently the pBin repacker and csv ex/import is not implemented, use a hex editor.
The eboot (elf tool) has some limitations, by clicking on File->Save ELF only the currently selected type is saved.
Some elf types (like skills, digimon and other) have a fixed text limit, it cannot be changed.
The free size is always calculated by shift-jis text length + 1 for the 0x00 terminator byte.
If the free size is below 0, the tool will not save the elf.
As a bonus i added an old tool by me, MagicCodeRenamer, it reads all files in a directory and checks if it has no extension,
then it reads the file header and based on database.txt it can than add an extension to it.
It makes identifying of file types easier.
