can someone explain to me why PS/2 has three very similar scan code sets and all of them are cursed beyond belief

Did I ever tell the story of DVDX on the Wii? It was a hack that granted DVD read perms to your app. By launching itself, an app that has DVD read perm. Which hard resets the PPC CPU. And reboots the ARM too. So I save/restore PPC and PI register state around the launch.
It was like suspend/resume code, but cursed. And I relied on title launch latency, kicking off the launch asynchronously while I went off to save the last bit of state. DVDX itself was just a branch to a vector in RAM to get back to the app code and restore everything.
