Reasons

• RPCS3 uses free license so they’d have to share their fork to the public.
• Licensing issues for old games
• Cost

Honestly, I think while they had a financial incentive, they probably also just didn’t want to bother with the all the work required to add production-level support for PS3 games and and the maintenance complexity of supporting it.

It’s one thing to develop a strong proof concept, there is a lot more involved with getting it to the market as commercial product (with guarantees and support).

That being said, excellent work by the folks who figured this out.

“for some reason”

I can think of a few rea$on$.

The PC can also do that and Bill Gates just turns a blind eye
