Modder successfully runs Counter-Strike clone at 60 FPS on the original Sony PSP — created his own Rust-based 3D engine to power 480 x 272 gameplay, also works on PS Vita

Barely a day goes by without some retro system developer accomplishing a technical feat that beggars belief. OpenStrike is the latest mad project, creating a proof-of-concept reimplementation of the seminal Counter-Strike for the Sony PlayStation Portable (PSP), a 22-year-old system that arguably has no business running the game.

The port was made by Yifeng Wang (aka doodlestrike), who apparently created his own Rust-based 3D engine called Pocket3D for the affair, along with the PocketJS JavaScript engine for the game rules and UI. Despite the proof-of-concept status, Wang says that elimination matches with bots are already playable, though the game’s famous buying stages aren’t yet functional. The full set of eight original Counter-Strike maps have already been tested, and interested modders should easily be able to roll their own.
