Heres a quick guide on how to sign your own homebrew using the tools released at wololo.net by bbtgp and JJS. Thanks to the devs there we have a quick and easy solution to run homebrew on OFW! The first thing you need to do is download these things:
Download and install pbp unpacker, then open an eboot.
Now click on extract and put it all in a new folder that you can find.
Now that you have everything extracted open up the Signing Tools zip file and copy everything over. Then run the "SIGN_ME" bat file (only once!) and it should work, the cmd screen will open and close quickly and your data.psp should be larger in size. Now that thats done create a new pbp in pbp unpacker, and load each file up from the prompt screen that is available, font worry if your eboot doest have everything.
Now remember that some homebrews may be too large, so stick to files less than 5mb (the data.psp that is) Good luck with signing.
