    The PSP’s maximum resolution is 480x272. It runs on a 333 MHz MIPS processor with 32MB of RAM (64MB on PSP-2000/3000). Forza Horizon 1 (released 2012) requires a 2.66 GHz dual-core CPU and 2GB of RAM. It is mathematically impossible to compress Forza Horizon to run natively on a PSP without completely rebuilding the game from scratch.

    Believe it or not, in the underground modding scene (GBAtemp, Wololo, PSPKing), dedicated fans have created texture and sound mods that turn Test Drive Unlimited or Need for Speed: Underground Rivals into a pseudo-Forza experience.
