DeSmuME Manual for the Windows port
Quick Getting Started Guide
When you start the emulator for the first time, you probably just want to play a certain game. You can do this by going to 'File' in the menu, and selecting 'Open Rom'. This will open up an explorer window, within which you can browse to the rom (nds file) that you wish to play. Once the game has finished loading (and this should only take a few seconds at most), your game will automatically start running.
The rest of this manual will be spend on explaining all the other options in the menu.
File | Open Rom
This option is for loading games. A game is typically called a rom file. Just use the explorer window to browse to the file, and click on open. The game should just load and start. The desmume windows port is also able to load some compressed formats, like zip, rar, and 7-zip. Just as long as there is a valid game (rom) file in the compressed archive ending with an .nds extension, it should load fine.
File | Recent Rom
This menu option contains a list of the roms that you have most recently loaded. You can quickly access a game that way, without having browse to the right directory with the 'Open Rom' option.
File | Rom Info
This option offers some information about the internals of the rom file, like name, code, manufacturer, and size. This should not concern the casual gamer, but may come in handy for developers.
File | Save State As...
Imagine you have gotten to a certian point in a game, and you need to do something else. The emulator let's you save the current state of the game, so that you can continue the game later at precisely the same point somewhere in the future.
File | load State As...
Once you have saved a game's position, or 'state', you can load it again with this option.
File | Save State
This option works fairly similair to the 'Save As' option, altough it let's you save numbers instead os specifying a chosen name. Also, All the states saved via this option end up with a pre-determined name of 'game (rom) name'.dsx. So if the game is called MyGame, the first savefile will be called MyGame.ds0, the second one MyGame.ds1, etc.
File | Load State
This option let's you load the states that you saved via the 'File | Save State' option
File | Import Backup Memory
Backup Memory is the data the game uses to remember its own state. It is stored on the cart in a normal game. The file format is '.duc'. .duc is the same thing as .sav but a different format. People use pro action replays to capture it from their card and post it online without using emulators. Go to gamefaqs.com and find a '.duc' save file for a game you can use that function to import it into desmume. Its the save file. save ram. where your saved game goes. desmume calls it .sav file
File | Save Screenshot As...
This lets you take a screenshot of the current view of the emulator, and specify it's name to save as a bitmap (.bmp) file.
File | Quick Screenshot
This option also dumps a screencapture, but it has a pre-determied filename and location. It will be called printscreen.bmp, and located in the current directory. In Windows, this is probably the same folder as where your desmume binary is located.
File | Record AVI
This option lets you capture what's going on in the emulator, and save it in an avi file.
File | Stop AVI
The 'Record AVI' option continues to record the game, untill you press the 'Stop Avi' option.
File | Quit
Choosing this option exits the emulator.
Emulation | Pause
This option will pause the emulation, freezing it at the current moment of execution. Selecting it again will resume the execution of the ROM at the exact moment where you paused it.
Emulation | Reset
This option will reset the ROM that is currently loaded to the very start of the ROM, just as if you chose 'File | Open Rom' again.
Emulation | Shut Up
This option turns off all the sound.
Emulation | GBA Slot
This menu option pop-ups a new window, which lets you specirfy what to do with the GBA slot of the Nintendo DS. It has the following choices : NONE, Compact Flash, Rumble Pack, GBA Game. Rumble pack allows some games to use vibration. Memory extension... Extends memory. And some DS games can have bonuses, unlockable by GBA cart. For example in Megaman ZX you can fight some Megaman Zero Bosses when correct cartridge is inserted. There are also other GBA slot extensions, like... a Guitar hero controller. But these are currently not emulated by desmume. Flash Cartridge is used for homebrew software emulation, for example that uses DLDI ( Dynamically Linked Device Interface).
Emulation | Cheats
This option pulls down a drop-down menu, and presents the options list and search. Be aware though, that cheats are sort of half baked right now. If you are not having luck, wait for some news on an improved cheat system.
Emulation | Cheats | List
Choosing 'list' will list all the currently known cheats.
Emulation | Cheats | Search
Choosing 'search' will let you search for cheats.
View | Rotation
This option will let you rotate the screen a pre-determined amount of degrees. The options are 0 (no rotation),90 ,180, and 270.
View | Window size
This option will let you enlarge the windows a pre-determined size. The resize options are: 1x, 1.5x, 2x, 3x, and 4x the default size.
View | Screen Separation
This option controls how far the two windows should be apart of each other, in other words: how big the border between them should be. Valid choices are: None (which is the default), narrow border (which is slightly larger), DS (which is about the wsame amount of room there is on a real Nintendo DS).
View | Force Maintain Ratio
Here you can choose, when re-sizing the windows, if you wan to maintain the ratio of the windows. You can select or de-select this option.
