A modder by the name of tschicki has built a custom "PlayStation 2 Portable" from scratch, powered by a reverse-engineered motherboard that features original PS2 silicon. The hardware sits inside a 3D-printed shell with proper controls, USB-PD charging, and a bespoke cooling solution. The project is entirely open-source and available on GitHub for anyone to follow along with, if you have the right skills and patience required.
Work on the PS2 Portable actually began way back in 2022, but it was only made public last year. The four-year development period really shows when you take a look at how polished the finished product is. The design is inspired by modern handhelds such as the ROG Ally; it has an ergonomic shape with large grips that house two 5000mAh batteries to enable up to 4.5 hours of playtime on a single charge.
