I have a 3.03 OE-C firmware PSP and was planning to update to 3.52 M33-4, until I was confused about something:
Once updated to 3.52 fw, will I still be able to use a flash program (Slash-N-Flash v3 or Flash Agent H1) to install topmenus, gameboots, and fonts that I use with Flash Agent on 3.03 OE-C fw?
I read about .rco files (such as topmenus) and having to update them in order for them to work on an updated firmware. If this is the case, how would I go about updating such files?
I've been struggling for quite some time. Any help is appreciated.
