FCEUX is a cross platform, NTSC and PAL Famicom/NES emulator that is an evolution of the original FCE Ultra emulator.
It is a fork of Bero’s FCE, and has become far more advanced than its predecessor.
FCEUX contains all features and enhancements from FCE, FCE Ultra, FCEU rerecording, FCEUXD, and FCEUXDSP as well as many new mappers from FCEU-mm.
Features include:
- All official instructions of the NES’ CPU, the 2A03, which is compatible (mostly) with the 6502, are emulated.
- 8×8 and 8×16 sprites.
- Sprite hit emulation(including checking the bg color).
- 8 sprite limit (and flag emulation).
- Screen/Sprite disabling, with correct color replacement.
- Color deemphasis.
- Strip colorburst bit emulated.
- CPU-instruction granularity for special mid-scanline effects (mostly CHR switching, such as used in “Pirates!”, “Marble Madness”, and “Mother”).
- Many palette features, including loading a custom palette to replace the default NES palette.
- Emulates the standard NES gamepad, the Four-Score multiplayer adapter, the Zapper, the Power Pad, and the Arkanoid controller. The Famicom version of the Arkanoid controller, the “Space Shadow” gun, the Famicom 4-player adapter, the Family Keyboard, the HyperShot controller, the Mahjong controller, the Oeka Kids tablet, the Quiz King buzzers, the Family Trainer, and the Barcode World barcode reader are also emulated.
- Supports the iNES, FDS(raw and with a header), UNIF, and NSF file formats.
- Supports loading ROM/disk images from some types of compressed files. FCE Ultra can load data from both PKZIP-format files and gzip-format files.
- Battery-backed RAM, vertical/horizontal mirroring, four-screen name table layout, and 8-bit mapper number capabilities supported.
