Many of us get a sense of warm nostalgia when it comes to the PSP. Released in 2004, this portable console was a real breakthrough for its time. It introduced us to the possibility of enjoying full-fledged game projects on the go. It was incredibly groundbreaking at the time. As if you had a little piece of home console in your pocket.
I found the only reason I was attracted to the psp was because of the ease of cracking it. For about $60 you could get a magic battery and a j-stick. That let you go rent a game rip it and throw it onto a hard drive. Boot the game straight from the memory card which was surprisingly not a Sony proprietary card but a regular micro SD. Same reason I still have my third gen Kindle. I can download all the books for free.
I have a D01100 its a gen4 (my mistake). I just plug it into my computer or phone and transfer an epub right onto it. I never hooked it to an account. I even have a program to convert Manga but it's been awhile since I did that and I honestly can't even remember the name of the program or how it works. Had this thing since 07 so...
I google the book I want to read with "epub", download the file, plug my phone directly into my Kindle and use the file system just like I used to on a PC. Never really had to do much more than that.
