| binary solo said: I feel like HD remake of PS2 titles is kind of done. But if PS4 was BC with PS2 Sony could put basically the whole PS2 library (or at least the good games) on PSN and right there you have a reason to buy a PS4 to replace your PS3 even if the actual PS4 library doesn't have much to offer you. Sure with PS Now you will be able to stream some PS2 games without having to have built in BC. But it takes time and effor to convert a game to play via internet streaming, I assume, and how long will it be before a substantial number of PS2 games are on PS Now? It takes bugger all effort to plonk a game on PSN for normal old downloading. And then you have the people who still have a PS2 collection who like to play from time to time, and PS2 BC on PS4 would mean only needing 2 consoles in the house to be able to play all 4 generations of Playstation home console games. PS4 must have sufficient processing power to be able to emulate PS2 without any problem. |
The PS1 uses a MIPS CPU which is RISC based ( Reduced instruction set computing )
The PS2 uses a newer version of the PS1 so full BC is easy.
The PS3 used a IBM POWER CELL CPU which is also RISC based as so was capable of dealing with the much older PS1 but not the PS2 BC.
PS4 uses an AMD X86 with X64 extension CISC ( complex instruction set computer ) CPU that in some opertations is a lot slower than a CELL ( the best Intel $1000 CPU's are slower than CELL in some operations ) and as such can not give BC for any previous RISC based console.
