It turns out Sony had plans for a battery-powered PS1 crammed inside a DualShock controller, and it would have been a plug-and-play precursor to the PlayStation Classic. Armed with a memory card slot and a moulded composite video cable, it would have provided the Brazilian market with a way to play ten classic games via a memory card, but "Sony Licensing couldn't get their act together about the royalty terms."
Dubbed the PlayStation PUGA, the retro console Dualshock hybrid features in a talk by legendary game developer Brian 'Biscuit' Watson. Hosted at The Retro Collective vintage computing museum in Chalford, UK, the ex-DMA Design dev spills the beans on their 40-year-long career within the industry, which includes his time at Sony working on PS2 emulation and the cancelled PS1 plug-and-play prototype.
