What bsnes-plus is
bsnes-plus is a free, open-source Super Nintendo and Super Famicom emulator with debugging tools for SNES software. Its debugger pauses and resumes emulation, single-steps the SNES CPU and active coprocessors, and saves execution traces. Memory tools inspect and edit CPU, APU, VRAM, and other address spaces while highlighting known code and data. Tile, tilemap, sprite, palette, and hardware-property views are included, along with SA-1 and Super FX disassembly and debugging. The emulator supports SNES cartridge images, Satellaview and Sufami Turbo images, save memory, patches, and cheat files; Satellaview support includes BS-X cartridges and Memory Packs. Plugins add compressed archives, additional ROM extensions, Game Boy and Super Game Boy ROMs, and music files. Compatibility mode lowers accuracy to reduce requirements, while accuracy mode targets higher hardware accuracy. A 64-bit Windows release is listed, Linux build instructions are provided, and macOS is forthcoming. Internet multiplayer is not supported or planned.
