I noticed sites started putting ps vita roms and last time i asked here the hacking scene could only play PSP roms and emulators if the console was on firmware 3.60 i believe. What i want to know is : if i buy a ps vita now 1 - Can it be able to play ps vita and psp roms? If so a quick guide would be appreciated. 2 - If i get my hands on a used console with firmware above 3.60, is it downgradable? 3 - Can i put a 128gb micro sd card in it to store all the games i want via some sort of card with a slot in it? 4 - Is there a model best for it all (i don't own a 4g phone contract just basic wifi at home) Thank you!
