- tobz1000 3y agoIt sounds more like the I/O firmware was running on dedicated PS1 hardware: https://www.theguardian.com/technology/2013/dec/12/ps4-and-xbox-one-so-why-arent-they-backwards-compatible https://www.theguardian.com/technology/2013/dec/12/ps4-and-x... > The PlayStation 2, meanwhile, had the original PlayStation chipset built in, so it ran pretty much any PSone title – and when that chip wasn't being used for backwards compatibility it doubled as an input/output processor, which was pretty canny.
- helf 3y agoI can't find anything claiming this. This is literally the first time I have ever seen this claim. The original fat PS2 including majority of the PS1 hardware physically in the machine. More and more of it got offloaded to pure software emulation with later model revisions. I, too, would like to see info on this supposed "spare die space on the USB controller" claim. Because it would be really neat if true lol
