NOTES: Reading the NFO that comes with the specific game is highly recommended, as it details specific points regarding the game it's packaged with. Renaming the original files is optional, but if you don't it can be awkward down the road, if (hopefully) a new CFW/HEN comes out.
Start by opening the folder containing the game you want to fix, which might be located at D:/GAMEZ/BLES00000/PS3_GAME
Rename the PARAM.SFO file to PARAM_ORIGINAL.SFO
Enter the USRDIR folder and rename the EBOOT.BIN to EBOOT_ORIGINAL.BIN
Then open the .RAR file containing the relevant fix for your game and double click on the .rar inside. In the new window that pops up, these are the actual N0DRM fixed files you will use (it's highly advised to read the NFO included via notepad, it will details specific solutions for each game it's packaged with).
Drag and drop the replacement file to where you have just renamed it's original.
NOTE: If there are any other files with different names, search the game's folder to find its exact location (might be buried in folders). Rename the original file and drop the N0DRM fixed file to the same locaton.
Then start transferring the game to your PS3's internal HDD or plug your USB drive into your PS3 and play from Multiman. Adding N0DRM PS3 Game Update Fixes to Your PS3 Games
The example game I am updating is Mass Effect 3, from the disk version of 1.00 to 1.05. If there are more updates to your game, just repeat the procedure using the latest versions which are fixed by N0DRM.
Start by downloading the official update, the official update version MUST match the version of the N0DRM patch you are applying (You can get official updates HERE and HERE). e.g. If N0DRM have a 100 and 105 patch, the 100 patch must always be applied to the games PS3_GAME folder. For the 105 patch, the official 1.05 patch must be downloaded and installed BEFORE applying the N0DRM fix and replacing the original files located at dev_hdd0/game/BLES00000 NOT dev_hdd0/GAMEZ/BLES00000.
Copy the UP0006-BLUS30853_00-PATCH01050000000-A0105-V0100-PE.pkg file to the USB drive you're going to connect to the PS3.
After installing the official PKG
Open the following location on your PS3, "BLES00000" depends on the specific game you're fixing: dev_hdd0/game/BLES00000/
Multiman OS View
After renaming the original files (optional), you can then copy (Press circle while hovering over the file) from USB or FTP via Multiman.
And then replace (Press circle and select paste) the files in their correct location (again, might be buried in folders).
Once you have the MASSEFFECT3.EBOOT.PATCH.105.USA.PS3-N0DRM files transferred to the right location, you're ready to select the game from Multiman and start playing!
