The slim PS2, like the fat PS2, has many different motherboard revisions - even under the same serial number. ![]() ![]() Meanwhile, PS1 games' GPU duties are performed by the PS2's graphics synthesizer in hardware (since it is a hardware successor - it is essentially eight PS1 GPUs glued together). _įAT PS2 has the PS1 CPU as an I/O controller, which acts as the CPU when playing PS1 games. Do we have reason to believe the chipset isn't integrated into a later revision of the PS2 chipset? Remember that PS2 games used the PS1 chispet for I/O and some other small tasks it didn't just sit there dormant when PS1 games weren't being played. The bit about separate EE/GS chips and unified EE/GS chips is taken from Wikipedia, so it could be false, but it lines up with everything else we know.Īll that tells us is that there's no discrete PS1 chipset. Later models removed/replaced the PS1 chip which is why the SCPH-7500X and later models are incompatible with certain PS1 and PS2 games. ![]() Well, it's confirmed by Voultar, who told the MLiG guys that the 7000X slims are essentially "perfect PS2s in miniature". Supposedly, this is the only slim model that has the PS1 CPU on-board (apart from the SCPH-70001), with later models resorting to emulation for PS1 games, as well as being the only slim to have separate EE + GS chips.Įh, is this confirmed? Or is this community heresy?
