RPCS3, the in-development PlayStation 3 emulator that recently drew some unwanted attention from publisher Atlus, just added support for two features that make last-gen games look really, really good.

High resolution rendering in RPCS3 adds support for “resolutions far exceeding what the PS3 could handle” — up to 10K, according to the emulator’s creators. “Although, we doubt many users will have the setup necessary to benefit from 10k today,” the creators wrote, “emulation is all about preserving for tomorrow.”
