NEShim

NEShim is a Windows shell that wraps the BizHawk NES emulation core and exposes Steam SDK integration, allowing NES games to be published on Steam as native Windows applications — with achievements, overlay support, Steam Input, save states, and a configurable front-end UI — without modifying the ROM.
