How do I install custom firmware on my PSP?

You need to ask your new network provider to give you the setting for internet browsing because you can not set up your v3 manually.
I tried to watch a YouTube video on my PSP (from the wifi internet) and it said I needed the latest version of Flash player. What happens if I do download it? Will it let me watch the videos?

They don't have a flash 9 built for PSP if you want to watch youtube on your PSP you will need custom firmware or a HEN depending on what system you have (1,2, or 3000) and will need to use PSPtube.
So I can get a regular computer controller to work, but my friend does not have one, she only has a psp. Considering it has a usb port, I heard that it can be used as a controller for the emulating system. I found a guide on how to do it, but the directions were so poorly written.
I have the same problem. I've downloaded the ZSNES emulator and installed the thing inside my PSP, but it doesn't work.

Mac DVD ripper could rip DVD to AVI, multiform videos/audios Rip DVD movie to video and audio formats including AVI, MPEG, WMV, MP4, DivX, H.264/AVC, MOV, 3GP, 3GP2, MP3, WAV, WMA, AC3, M4A, OGG, RA, AU, etc.

I'd recommenc you uninstall it because it possibly infected with malwares. You can get the feeling it is when you browse PSN later.
