I modelli "standard" di PlayStation 3 hanno sempre avuto la possibilità di riprodurre i giochi della PlayStation 2, attraverso varie formule di emulazione. Per spiegare meglio la situazione mi rifarò a un testo trovato sui forum di GameFaqs (https://gamefaqs.gamespot.com/boards/927750-playstation-3/71902014 - vedi sotto). Questa possibilità venne persa completamente con i modelli "slim" di PlayStation 3. Perché la vita, a volte, è proprio cattiva.
[Come funzionava l'emulazione di PS2 su PS3]
The Playstation 3 has many emulators, we're going to discuss the PS2 one. There are currently 3 emulators for dealing with PS2 games listed inside the PS3 firmware.
Emulator A - This emulator uses the PS2's CPU and GPU chip inside the PS3. This lets the PS3 play any PS2 disc you put inside. This is the most powerful "emulator", but in reality this is just a PS2 literally inside a PS3.
Emulator B- This emulator ONLY uses half of the components. The PS2's CPU chip is in place, the PS3 emulates remaining half of the PS2's GPU. This lets the PS3 play any PS2 disc you inside. Compared to Emulator A, this one has some visual oddities or framerate issues, but it is still a very high emulation playback of PS2 discs.
Emulator C - This emulator uses NONE of the PS2's CPU or GPU chips. This emulator relies on the PS3's powerful CPU, everything from the PS2 is entirely emulated on the PS3. When you download and play PS2 Classics from PSN, this is the emulator your console uses. This is the only emulator that doesn't play PS2 discs. Every PS3 has access to this emulator regardless if they're backwards compatible or not with PS2 discs.
When you go back and read the PS3's early documentation you find some interesting stuff for their tech. Using 2 Cell processors as CPU and GPU was one of the original design of the PS3 console, they had to quickly call NVidia at tail gate of the PS3's R&D to assign it a conventional GPU. Another treat was emulation. The PS1 was always going to be emulated regardless on PS3, the actual problem was PS2 emulation. Emulator C was the original intention of the PS3. To always software emulate the PS2, unfortunately when Microsoft announced and released the 360 far ahead of everyone else they had to speed up production and they used physical parts of the PS2 to get around backwards compatability. Sony later went back to this and were able finish the original PS2 software emulator. When the PS3 modding community got a look at the code, it turns out that this plays more than just Sony leads on with an estimated 60% of the PS2 library working on every single PS3 unit. Considering the age of the PS3 came from (before WiFi and HD standards), the strict 10x power requirement for emulation, RAM pool split between 512MB on CPU&GPU, its quite an impressive feat Sony was able to return PS2 emulation on the PS3.
Credo che non ci stiamo capendo. Con "emulazione" si intende che inserisci il disco della PS2 e le funzioni tecnologiche dell'hardware originale (cioè il lavoro di CPU e GPU e di tutto il resto) vengono elaborate da un software. Ma sì, continui a inserire il disco. Con PS3 Slim anche se metti il disco di un gioco PS2, è come se lo infilassi in un tostapane (utilità e risultati identici).
Ho forse dei ricordi distorti ma sono sicuro che una prima versione di PS3 poteva leggere i dischi della PS2.
Sì, lo fa, ma con un'emulazione via software e non via hardware (come era invece nei primi modelli distribuiti in Giappone e USA).
Una emulazione che poi è scomparsa in tutte le successive versioni di PS3. Corretto?

Ma quindi la possibilità di inserire un disco PS2 su PS3 prima versione non è mai esistita? Passato toppo tempo e ne ero davvero sicuro.

A questo punto ti chiedo la differenza concreta agli occhi dell'utente tra emulazione via software e via hardware.
