Don't know how many people know about this (isn't really advertised), but when I downloaded Castlevania:Symphony on the PS3 the other day, I also installed it on my PSP. Well I started a new game on the PS3, but it kinda sux to start again on PSP after alread playing for hours on PS3. But if you go to your saves folder, you can copy and convert the save to PSP and vice versa, so you can take the game with you where you left off. Also, if a PSN/PS1 game you download is one that you have OLD saves for you on your PS1 memory card, those can also be converted to PSP and you can play your old saves. Ie. I still have all my crafts and achievements from my old Wipeout saves from years ago as well as my 108% save from Symphony of the Night. Now bring on Final Fantasy 7, so I can go hunting for those weapons with my old save from years ago.
