I didn't see anything posted regarding this here, but I found this:

The app will patch the eboot of a game that requires a higher firmware...right on the memory card itself. Since I have a few slim units here, I have one that I kept on m33-6 for specific reasons. I tested it with Ghostbusters, GT, GTA: Chinatown Wars and a few other titles. Worked perfectly and decrypted the games just fine to run on the m33-6 system. So, if you are dead set on keeping m33-6, you might find this tool a necessity (not to mention easy to use). Here's a youtube link with video of it in action as well:
