1. How do I find out what version of CFW I'm using? I know I'm using 5.50 but don't know what version, also I have Prometheus installed. 2. Has anyone successfully gotten CheatMaster Fusion working on 5.50? It won't run for me. 3. I've heard of the new 6.xx PRO B4 CFW that was released. Would you recommend upgrading to that or sticking with my current FW? I don't really play PS1 games, although I might try in the future and I don't use many plugins other than cheats. 4. What USB ISO loader is recommended? I don't have a large memory stick and I don't mind being wired to my laptop while I play. Also, with regards to my 3rd question...will the USB ISO loader be compatible with the PRO B4 CFW? Thanks in advance.
