## Menu Items & Submenus

Config Toggle Switches

Explains the various toggle switch commands in the top two groups of commands under the Config Menu.

Hide Menu

Hides the Menu commands on the FCEUX main window. Press ESC to unhide the menu.

Region

Allows to choose between NTSC (224p@60fps), PAL and Dendy (240p@50fps) modes. For PAL, FCEUX will detect the proper choice when loading a ROM and set the flag accordingly (based on file name, where (E) is used by GoodTools to mark European ROMs). Dendy mode (sometimes also called Hybrid) is a modification of the NTSC one, it was used in some Famiclones and supports games released for the NTSC region, slowing them down to PAL speed.

Note: you can't change this setting while a movie is being played or recorded.

PPU (Sub-menu)

New PPU / Old PPU

As of FCEUX 2.1.2, FCEUX has a new PPU core. The new PPU has improved accuracy and greater game compatibility than the old PPU. However, some games may not work properly and there will be slight timing differences that would hurt movie compatibility. Also then New PPU is much slower than the Old PPU. Therefore, the old PPU is still the preferred setting.

Note: you can't change this setting while a movie is being played or recorded.

Enable (Sub-menu)

Run in Background

If enabled, FCEUX will continue to emulate when the window is not in focus. If disabled, the emulator will pause when out of focus.

Background Input

If enabled, FCEUX can continue to receive input while not in focus. (Useful for playing 2 FCEUX's simultaneously)

Auto-savestates

Enables the Auto-save feature. If enabled, FCEUX will make periodic savestates (once per every 256 frames) as you play or record a movie. You can right-click and select the "load last auto-save" in the context menu or press "Load Last Auto-save" hotkey to back up to the last auto-save savestate.

Frame Adv. - Skip Lag

This feature, if enabled, will cause the frame advance key (see movie recording) to skip over lag frames. It does this by reading the lag counter and skipping past any frames where input is not polled.

For instance, in a 30fps game (such as double dragon), frame advance will advance 2 frames instead of 1.

Backup Savestates

Enabled by default. This option allows for savestate & loadstate Undo (& redo). (see context menu)

Compress Savestates

Enabled by default. This option compresses non movie savestates.

Game Genie ROM

Allows the use of the game genie ROM. You must have a game genie ROM named gg.rom (it is safe to rename a game genie.nes file to gg.rom) and it must be in the FCEUX base directory (which is the folder fceux.exe is in unless you specified a different folder in the Directory Override Menu).

If enabled, FCEUX will open gg.rom first when you load a new game. Any codes applied in the game genie screen will be applied to the game just like on a real NES.

(Remember that enabling/disabling Game Genie emulation will not take effect until a new game is loaded)

Note: Game genie codes can also be added with the Game Genie Encoder/Decoder via the Cheat Search Menu (and this method does not require a game genie ROM).

Auto-resume old play session

If enabled, FCEUX will make a special savestate every time you close ROM, and will automatically load the savestate when you open this ROM next time, so you can continue from where you left the game. In addition, when this option is enabled, FCEUX automatically loads the last used ROM on startup.

Display (Sub-Menu)

Input Display

The input display will display 1-4 pictures of a NES controller at the bottom of the screen. When playing/recording a movie, these controllers will display the input that is captured in the file.

When input comes from a movie file rather than then user, it is displayed in a different color (silver)

The input display can also be toggled by hotkey. The default key for toggling the Input display is the "," (comma) key. (This can be re-mapped in the Map Hotkeys Menu).

Lag Counter

The lag counter will increment every time to the game fails to poll for user input. It will display in red on any frame that is currently lagging and will increment the lag counter by 1. These situations occur when the game is lagging (too much information to process), or the game is in a screen transition state (so not polling for user input). In a 30fps game (such as Double Dragon 2), it will increment every other frame.

The lag counter value is stored in savestates.

Displaying the lag counter can also be toggled by hotkey. The default key is the "/" (slash) key. (This can be re-mapped in the Map Hokeys Menu).

Frame Counter

Toggles the display of the frame counter. The frame counter will increment once per frame.

The frame counter display can also be toggled by hotkey. The default key is the "." (period) key. (This can be re-mapped in the Map Hotkeys Menu).

Rerecord Counter

Toggles the display of the number of Rerecords done when making a movie. The Rerecord counter will increment every time you load a savestate in Recording mode.

The rerecord counter display can also be toggled by hotkey. The default key is the "M" key. (This can be re-mapped in the Map Hotkeys Menu).

Movie status icon

Toggles the display of "pause", "play" or "record" icons in the lower right corner.

FPS

Toggles the display of average FPS counter in the upper right corner.

Graphics: BG

Turning this off will turn off the backgrounds in the game.

Graphics: OBJ

Turning this off will turn off the objects (sprites) in the game.

Note: You can set the default color when the Backgrounds are turned off. To do so, open fceux.cfg and change the value of the entry named: gNoBGFillColor

Save Config File

Saves current settings to fceux.cfg. Normally settings are not saved until FCEUX is closed.
