What vibe-sms is
vibe-sms is a free Rust emulator for Sega 8-bit systems: Master System, Game Gear, SG-1000 and SC-3000. It handles Master System and Game Gear Mode 4 graphics, plus TMS9918A modes for the SG-1000 and SC-3000. Audio includes SN76489 PSG, YM2413 FM synthesis and Game Gear stereo output. Players can remap keyboard controls, connect gamepads, use a mouse-controlled Light Phaser and play with two players. Nine save-state slots are available, with F7 saving and F5 loading. Battery-backed SRAM is stored beside ROMs as .sav files, while compatible EEPROM cartridges use .eep files. ROM extensions .sms, .gg, .sg and .sc identify systems automatically. Downloads cover Linux, Windows and macOS, including Intel and Apple Silicon builds. Linux provides an egui menu-bar fallback described as Wayland-compatible. The README lists Linux dependencies, while Windows and macOS need none.
