1. You MUST have the PC drivers for PSP Type B installed, and have usbhostfs setup. Have a look at
this old tutorial for getting the USB working in devhook - the principle (for the PC part) is the same (ignore the PSP bit)
(I had written a nice new tutorial for this, but my browser decided to crash on me, so...)
2. The FLASH0 folder from within the rar package is not to be put on your memory stick - Re-read the tutorial, it explains in detail how to turn on the USB to connect to your firmware's Flash0 space (steps 7 to 10) - you MUST be careful doing this or
YOU WILL brick your PSP.
3. It will work with USB 1.1 or 2.0, but it will be VERY slow on 1.1!
4. NoUMD - some games yes, some games no - basically the same as if you had the iso on your memory stick! (ie try it and see!)
5. The USB sound will turn off and on when going between the XMB (VSH) and Game (GAME) - this is why you must have the plugin enabled under both situations!
It may also do it rarely during game play - although i've not had any problems with this (game loading pauses sometimes) it may cause some games to crash (so save regularly!).
6. I will only be answering legitimate queries from now on. Some of the above is already covered in the relevant tutorials - i have expanded on some of it though.
If you aren't sure how to do something and can't follow instructions -
Should you really be attempting it?
I think the majority of people here would agree with me on this (including ADMIN).
Sorry if you think i'm being harsh, but it's 1:30am, and i've just read some comments asking about something which if the instructions has been followed would not be an issue.
(p.s. This is me biting my tounge by the way!)
