The Libretro team has just released a new update for RetroArch, bringing some new quality of life features and improvements to the frontend, as usual. The first notable part of this new version, 1.9.12, sees the addition of a new core to the Steam version of RetroArch. The Picodrive emulator, which has support for Sega Master System, Genesis, 32X, and CD games, is now available for download as free DLC through Steam. RetroArch also now added a multitude of core support to various handheld emulation devices, such as the Pocket Go, New BittBoy, and PowKiddy Q90, which means mGBA, Genesis Plus GX, ScummVM, and more are officially supported.
