First of all I'm new to this brilliant site and very new to PSPradio which I really really want up and running on my PSP. I have a FAT PSP updated to 3.54 and have only got so far with putting radio on my device. I get the blue logo screen coming up ok when I open up games but then the message "game cannot open" or "file is corrupt". Then that's me stuck. I have followed the tutorial on here and also the video on Youtube from the English guy, whom I note is using the slimline PSP, and he operates on 3.52M33. My simple questions are: Can I actually get PSPradio on my PSP given my model and operating version, and if so, where am I going wrong? What does M33 mean when 3.52M33 is quoted? Sorry if I'm treading over old ground but I've only just discovered you guys, so don't put the boot in too much!! All help gratefully received!
