Just using your thumb for all navigation seems like an RSI waiting to happen.
Also I don't know who in the last couple years decided it's a "Trackball Mouse" it's just a Trackball in the same way it's just a "Trackpad" and not a "Trackpad Mouse"
You got me curious so I googled it, are you confusing it with a port for the Playstation Classic? Thats a modern console that uses a Android phone chip and emulates the PS1. I couldn't find any references to the original PS1 and I don't think any amount of wizard coding could get that game to run on such a resource constrained hardware. There is so much of that game that was only possible on N64 level hardware or better.
If the goal however is not to tinker but to really build and learn AI, it is going to be financially better to rent those GPUs/TPUs as needs arise.
