Super Famicast
What Super Famicast is
Super Famicast is a Super Nintendo Entertainment System emulator for Sega Dreamcast, available as open-source software under GPL-2.0. It is a port of Snes9x that uses v1.42 code, along with a SH4 assembler CPU core from DreamSNES. Many games emulate at full speed with frame skipping. ROMs can be loaded from CD, including a disc shared with the emulator, and users can swap to another CD containing ROMs. The emulator saves game SRAM and settings to a VMU, but currently sends all VMU saves to the first one it finds. Users can adjust screen positioning, enable bilinear filtering, switch themes that may include background music, and configure D-Pad or analog-stick input. A Dreamcast mouse works with supported SNES games. Sound has a major limitation: enabling it slows gameplay to about an unplayable state and is out of sync. The releases page lists versions 1.0 and 2.0 from 2004, and SourceForge labels the project Beta with a last update of 2013-03-20.
Who it suits
Super Famicast suits people with Sega Dreamcast hardware who want to play SNES ROMs from CD. It may appeal to users comfortable with a project labeled Beta and its documented sound and VMU limitations.
