cxNES (deb) (32bit)
cxNES is an open source, cross-platform NES/Famicom emulator. It is mainly written as a part-time hobby project to suit the needs of its author, but with accuracy, performance and portability as primary goals.
cxNES is written in C and uses SDL 2.0 for graphics, sound and input, and GTK+ for the GUI toolkit. It should have the same functionality and roughly the same look and feel on all supported platforms. Currently only Windows and Linux are supported.

Patching
* Supports IPS, UPS and BPS patch formats
* Autopatching support

* Patches may be applied via GUI or specified on the command line
* Patches may be included in ZIP files with ROMs or disk images
Video
* Bisquit’s NTSC palette generator
* Blargg’s nes_ntsc filter
* User can specify a 64 or 512 color external palette file to be used instead of the generated palette.
* Enhanced sprite limit workaround: limits sprites for scanlines where the limit appears to be exploited intentionally, otherwise does not limit sprites.
* Supports correct TV aspect ratios for NTSC and PAL consoles
* PNG screenshots
Input
* Flexible input binding support
- Nearly all emulator actions can have custom keyboard and/or joystick mappings
- User-defined ‘modifiers’ useful for button combos on gamepads with few buttons (such as standard NES controllers)
* SDL GameController API
- Allows supported joysticks (including XInput devices) to have a common set of sane default mappings.
- Additional gamepads may be added by editing a plain-text mapping database
- SDL Joystick API also supported for devices not recognized by the GameController API.
* Turbo support for controllers
- Supports dedicated turbo buttons
- Supports toggle buttons to enable/disable turbo on the standard A and B buttons.
Misc
* Savestates
- Can auto-load/save states on ROM load/unload
- Can auto-save state at a user-specified interval
* Dynamic audio resampling
- Uses Blargg’s blip_buf resampler
* Cheat support (Game Genie, Pro Action Rocky, and raw formats)
- Cheats can be auto-loaded/saved on ROM load/unload
* ROM Database (optional) for handling ROMs with incorrect or missing headers.
* Can be compiled or run without the GUI
* Can specify configuration options, patches and cheats on command line
* FDS enhancements
- High-level optimizations of FDS disk I/O routines (optional)
- Automatic disk selection and change for most FDS games (optional)
- Writes to FDS images saved as IPS patches
* Windows builds can be configured to run in portable mode, storing all user data (save files, states, etc.) in the application directory.
