Overview
Reverse engineering of PlayStation CPU GTE.
The aim of this project is full discovery how Pops emulating GTE and write own port for some of freeware Sony PlayStation emulators (e.g. Pcsx). DEPRECATED
Since Pops is buggy shit, new goal is: drop acid on PSX CPU, microscope it, find GTE, recover standard cells and study its logic layout.
GTE was always kind of mystery for PSX emu authors, now we have a chance to look how it was made of silicon.
Overall progress:
- Decap CPU DONE
- Microscope top metal layer (M2) on 20x zoom DONE
- Microscope bottom metal layer (M1) DONE
- Trace both metal layers
- Delayer metal and microscope diffusion layer DONE
- Trace diffusion DONE
- Find all combinations of standard cells DONE
- Locate GTE DONE
- Restore GTE logic ci
