I have a magic memory stick made out of an old 512mb card i have, and I use it all the time with a pandora to flash PSPs. Thats all i use the card for, but i'd like to put more (or just a single 3.90m33-2) update on it. Right now it flashes to 3.71 m33-2, then i use a file manager on the psp to rename another folder to UPDATE, then update it, and switch it back. Is there an easier way to do this? I've looked everywhere and even looked at MUX 2.1, but i don't really want to mess with the memory stick too much so i don't risk crippling it.
