| PSP Firmware Upgrade(?) Hi,
I'm an owner of a PSP slim with firmware version of 3.90 M33-2. I was told that I needed to upgrade to play some new games that I wanted to install. I did some searching and found version 5.50. I was about to install it but hesitated at the last moment as I remembered there were versions that once you installed, you would not be able to play ISOs or would not be able to downgrade from.
So my question is, what's a good (firmware upgrade) version to download?
Oh by the way, I'm not sure if this is the right thread to post this question or if valid at all. If not, then my apologies.
Thanks! |
