This won’t work for backups because their eboot is encrypted. It will work for homebrew though.
Step 1: Insert usb stick into PC. Make a folder named PS3_GAME on your usb stick. Inside that folder make a folder called USRDIR.
Step 2: Make sure your application is named EBOOT.BIN (if its homebrew you made, it will be whatever.self, rename it!) Note: if your application is one you downloaded, it will probably be in a pkg, you must extract the pkg to get the EBOOT.BIN.
Use “make_package_npdrm.exe -x whatever.pkg”, to extract it. You may also grab the extracted pkg files by using FTP after installing the pkg. If the EBOOT.BIN is from a pkg that means you will need to run “unfself.exe EBOOT.BIN EBOOT.ELF” and then “make_fself.exe EBOOT.ELF EBOOT.BIN” to get it in the format needed to run from app_home. Then delete EBOOT.ELF. (we will not provide you with the above mentioned exe’s find them yourself!)
Step 3: Place EBOOT.BIN into the folder USRDIR that you made on your usb stick.
Step 4: Place your app’s PARAM.SFO and ICON0.PNG into the folder PS3_GAME that you created. If you don’t have these files, you will need to look into how to make them. I will not provide that info here.
Step 5: Insert usb stick into ps3, scroll to app_home/PS3_GAME, highlight, and select it to run it.
