Background

Port of Snes9x 1.52+ to Libretro (previously called SNES9x Next). Rewritten in C and several optimizations and speedhacks.

Provides more favorable performance thresholds at the cost of accuracy. DO NOT use this core unless you have underpowered hardware and the mainline Snes9x core and the bsnes/higan/bsnes-mercury cores aren't fast enough

This core is part of a group of Snes9x cores that are snapshots from the year their code is based on. (Snes9x 2002, Snes9x 2005, Snes9x 2005 Plus, Snes9x 2010)
