FCEUX

Accuracy

Performance

Features

Fceux is an open-source Nintendo Entertainment System and Family Computer Disk System emulator. It's a merger of various forks of FCE Ultra. While not being cycle-accurate, it's has quite an accurate emulation and offers tools for debugging, rom-hacking, map making, Tool-assisted movies, and Lua scripting

2.1.4 is a maintenance release that fixes these bugs in 2.1.4:

fix crash bug on .fcm convert

fix erroneous reporting of savestate past the end of movie error during read-only loadstates

Released 31 May 2010


The 2.1.4 release fixes many bugs and adds new features compared to 2.1.3. In addition it also fixes up the movie code significantly; fixing implementation problems, loading speed, adding new features, and fixing bugs.

Common

  • Added microphone support option. When enabled, Port 2 Start activates the Microphone

  • Prevent .zip files containing no recognized files from causing crash

  • Autohold - Added player 3 and 4 to autohold notification window, labeled controller input

  • mapper 19 savestate fix mirroring for "Dream Master (J)" corrected to "four-screen" by CRC check

  • Disable auto-savestates during turbo

  • Fixed so Gotcha! auto-enables the zapper

  • Autohold - Added player 3 and 4 to autohold notification window, labeled controller input


Movies

  • Fully implemented "bulletproof" read-only

  • Movie code now fully conforms to the Savestate section of the Laws of TAS

  • Fixed a potential desync that plays out an extra frame without an update to the frame count involving heavy lua use, joypad.get, and a loadstate

  • Movie support for microphone

  • Movies now have a "finished" mode.  If a playback stops the movie isn't cleared from memory, and can be replayed or a state loaded Similar functionality as DeSmuME and GENS rerecording

  • New PPU flag in movie headers (doesn't change an emulators PPU state when loading a movie)

  • Much faster movie loading and movie-savestate loading

  • Made gamepad 2 off by default (so less movies should have unused player 2 data)

  • Implemented a "full savestate-movie load" mode similar to the implementation in VBA-rr and SNES9x-rr.  In this mode loading a savestate in read+write doesn't truncate the movie to its frame count immediately.  Instead it waits until input is recording into the movie (next frame).  For win32 this feature is togglable in movie options and the context menu.  For SDL this is off by default and a toggle will need to be added

  • Movie + loadstate errors are handled more gracefully now, with more informative error messages and the movie doesn't have to stop if backups are enabled

  • Fix PlayMovieFromBeginning when using a movie that starts from savestate

  • emu.delgamegenie()

  • savestate.object() which is savestate.create() with intuitive numbering under windows

  • gui.getpixel() which gets any gui.pixel() set pixel colors, and possibly other functions

  • emu.getscreenpixel() which gets the RGB and Palette of any pixel on the screen

  • lua function movie.getfilename() which returns the current movie filename without the path included


Input Display

  • Input display updates on loadstate

  • Input display overhaul that uses different colors for different input contexts

  • Input display now shows both currently pressed buttons and buttons held the previous frame


Win32

What's New? 2.0.0

FCEUX has all the latest tools, enhancements, and features from FCEU 0.28 rerecording and FCEUXDSP 1.07  In addition, it has many new tools, bug fixes, and enhancements not seen in previous branches.


General

-A detailed Help Menu!  No longer are you aimlessly searching the internet for long lost info on FCEU's options!

-Numerous Dialog box reformats.

-FCEU remembers its last screen (x,y) position.

-Increased command line options

-More options under the Directory Override Menu

-A Turbo Toggle option (turbo now can be toggled on rather than having to hold the key down)

-More hotkey assignable options in the Map Hotkeys Menu.

-A lag counter

-Autofire uses the lag counter (so it will skip over lag frames)


Movie support

Overhauls in both the movie and savestate file formats.

.fm2 File format

The .fcm file format has been overhauled into a new .fm2 format.  Changes include:

-Uncompressed and text based format.  Movie editing can be done simply in a text editor.

-Recording from soft reset option removed.

-Recording from start (hard reset) no longer has an empty savestate at the beginning.

-GUID inserted into movies for better savestate/loadstate error handling.

-Rather than an Author field, it has a full metadata menu where an author can put any info needed.

-A tool to convert .fcm files to .fm2 files.

-More specific info on .fm2 files in the .fm2 documentation.


Savestate/Loadstate

-New savestate file format.  NOTE:  Savestates from previous FCEU versions CAN NOT be used in FCEUX.

-Fully functional error handling (savestates from other movies cannot be loaded).

-Read-only toggling related bugs fixed.

-Savestate filenames include the name of the movie (if a movie was playing when made).  This prevents loading wrong savestates. (This also means that savestate 0 is different when a movie is playing and when it is not).


7z Archive Support

-ROMs in any 7z compatible compressed format can be opened directly.

-If more than one valid ROM exists in an archive file, then a dialog box will open with a list of available ROM choices.


TAS Edit

-A brand new powerful movie making tool that revolutionizes the way TAS movies are made.  See TAS edit.


New Tools

TAS Edit - a revolutionary new way of making TAS movies.

Input Presets - a system for quickly toggling different input configurations.

-A "load last file" option.  If checked, memory watch will load the last file used


Cheat Search

-Now has a minimize button

-Cheat Search Menu from FCEUXDSP (a major overhaul compared to other FCEU branches)

-Possibilities update while playing/frame advancing a game

-Double clicking a value in the possibilities window sends the value directly to Memory Watch


RAM Filter

-Double clicking a value in the possibilities window sends the value directly to Memory Watch


Lua Scripting

-Uses the latest features of Lua Scripting from FCEU 0.28

-Many enhancements and new commands including dialog creation commands!  Now scripts can create their own dialog's and GUI features.


Lua Basic Bot

-Basicbot removed (from the rerecording version of FCE Ultra).  In its place is lua bot.


AVI Recording

-"Movie playback stopped" message recorded in AVI by default

-Turbo Toggle Hotkey.  (Allows turbo to be left on for a faster AVI capture).
