Copy your save file into the USB and wait for it to be copied on to your USB. When you load up your PS3 go to 'Save Data Utility' and find your RE4 file and press triangle and press x on copy.
Now hold on to the PS3 folder for a bit since you need to actually get your OWN RE4 file into the USB which will also say PS3 but will have your DATA but not mine.
First you want to download the link in the resources page that I have provided and it will have a folder named 'PS3'. Now to do this you want to have a USB and your PS3. Please be aware that you should back up your save file first just in case if you want to actually keep your save file and have your own optimization with your inventory and such because you won't be able to save at all when you have successfully overwrite your file into mine. There will be a pre set save in the resources section.
For anyone who doesn't really want to take the time to grind all your weapons, grenades, and eggs.
