PlayStation 2 software is distributed on CD-ROM and DVD-ROM. In addition, the console can play audio CDs and DVD movies, and is backwards compatible with original PlayStation games. This is accomplished through the inclusion of the original PlayStation’s CPU which also serves as the PS2’s I/O processor, clocked at 36.864 MHz in PS2 mode.

They also pulled a really cool hack on Jak and Dexter. They were able to hack into the PS1 chip hidden away in the PS2 for backwards compatibility to get some extra processing power!

I read about it over a decade ago. Something about the game being difficult to emulate because of it. Now I can’t find anything :(
