(Overview of Program)

  It is quite easy to get started, below this you'll find more detailed information on Jnes and how to configure it.

  Generally to get started make sure you are running in the best color/colour depth, and simply open a rom-image

  from the file menu. This program also features a simple file browser that is enabled by default, you don't have to use

  it, but if you would like to browse a specific directory to check out mapper numbers, etc, this is a really handy to use and it also supports zip files.

International Patching System

 

  Jnes has the ability to apply IPS files if they are present when loading a rom image automatically. IPS files are

  commonly used to translate a game to another language, or more generally alter the games content such as graphics,

  program code, etc. To use this feature simply make sure the IPS file is in the same directory as the rom you are

  about to load, and make sure the IPS file is the same name as the rom image.

  Example: if you wished to apply an IPS file to "Megaman 2 (U).nes" your patch should be in the same directory

  named "Megaman 2 (U).IPS".  This is a convenient feature so you can ...

  • maintain the original rom image

  • use the latest patches easily

  • save some disk space?

  In the settings dialog there is an option that will make Jnes ask you before applying any patches it finds, or doing it

  without asking. See the dialog for more information. If you want some patches, visit the message board and links

  sections of the Jnes website.

 

Keyboard Shortcuts

  • Alt+Enter toggles windowed and full screen mode

  • ESC can be used in full screen to go back to windowed instead of above

  • F1 Resets

  • F2 Toggles pause

  • F3 Capture the screen

  • F4 Recording sound

  • F5 Save a state to file

  • F7 Load a state from file

  • There are a total of 11 save states available, they use the file extensions .js0 through .js9, the default state extension is .jst. 

  To change slots you may select the slot via the CPU menu, and also via keyboard shortcuts, the ~ key on the keyboard

  selects the default '.jst' slot for saves, and the keys next to it, 0 through 9, change the states accordingly

  (.js0 through .js9) The save slot setting is set back to the default .jst file extension at the load of a game.

 

Save Files

 

  All save states and sram are stored in a subdirectory called "\saves"  If you don't store the save files in this

  subdirectory Jnes won't see them, and Jnes automatically creates these directories on first-time saves so you don't

  have to do it yourself. But if you are importing or exporting a SRAM (".sav" file) file from another emulator keep this

  in mind. Important Note: It can be generally assumed that the save state format changes between versions of Jnes,

  this is because as the internal structures change, the states as a result may.

 

Cheats

 

  For using cheats go to the Help and Cheating section on the top navigation menu. For more information on using

  Cheats on Jnes please refer to Jnes Cheats Website Or the Cheat Offline Help Chm that comes already Packed with

  Jnes via Help\Using Cheats.

 

Kaillera Support - Netplay

 

  Kaillera support currently is implemented, but it's probably not perfect due to the nature of  networked gaming and

  emulation, things are bound to come up if you are not careful. The only trick to using it so far is exiting a game

  currently in progress, the first step is to close the ROM out in Jnes, doing File/Close causing Jnes to stop executing

  the game and requesting data from Kaillera, than exit the kaillera dialogs properly, than if you wish, exit Jnes. Using

  zipped roms are also implemented you can see how to set up your Netplay directory by clicking Directories Link
