Homebrew developer FreePlay recently released an update for NewBTCNFedit, bumping it up to version 0.2. For those who haven't heard of it, this application helps users build a customized pspbtcnf.bin file for firmwares not supported by PSPBTEdit.

Here's the changelog for version 0.2 of the application:

• Added checks for pspbtcnf encryption and proper file version
• Added check for whether the program was double-clicked; if you double-click it, it will display usage info, pause, and exit when you hit enter.
• Added support for Licenseapp mode - mode L, to go along with V, G, U, P, and A
