Why playing PS3 games on a PS5 is way harder than it sounds

digitaltrends.com:

PlayStation Plus Premium will give players access to a library of classic PlayStation, PS2, and PS3 titles starting this June, which is exciting as the PS5 only is backward compatible with the PS4 currently. Unfortunately, it comes with a caveat: All PS3 games must be streamed from the cloud and can’t be played natively on the console.

We’re over 15 years removed from the PS3’s launch, and there’s still no good way to play many classic PS3 titles like Infamous or Metal Gear Solid 4 on modern platforms. Sony is content to continue PlayStation Now’s approach to PS3 gaming with PlayStation Plus Premium. This stands out when Xbox and Nintendo are doing a relatively good job at natively emulating or remastering games from older systems for modern platforms.

To learn why PS3 games are so hard to bring to modern consoles, I spoke to Whatcookie, a contributor for the popular PS3 emulator RPCS3. Whatcookie, who chose not to share his name, is also known for creating a 60 frames per second patch for the PS3 version of Demon’s Souls. He broke down what makes PS3 emulation particularly frustrating and sheds some light on why Sony is content with streaming PS3 games from the cloud instead.

The system architectures of the PS4 and PS5 are so similar that isn’t much of a problem to run PS4 titles on Sony’s latest system, with a couple of exceptions. Compared to that, the PS3 has a different CPU that has more in common with the PS2 than Sony’s modern systems.

In short, PS3’s CELL microprocessor had some very unique capabilities, which meant that developers over-relied on the CPU at the time. This approach ultimately makes PS3 games harder to emulate. Whatcookie broke this all down for Digital Trends in greater detail.
