And by the way spoofing is not needed with new CFW anymore they only patch the sfo's. Sony didn't publish new keys since 4.30 for the eboots !
If you refer to modding/cheating ingame KDS way/tools is the best so far. If you want the easy way you also can use a cheat pkg. Regarding official updates most can be applied via MM natively some need new keys NPDRM keys which is as easy as
Install: Update (insert game name).pkg
Copy: Eboot form Update (Insert game name) folder on PS3 to USB stick
On PC: Change key
Copy Eboot back
PS: Only must be done for 1% of the games rest works natively
