Using JPeMu

A short tutorial explaining how to run an emulation through JPeMu.

Emulator Author : Tony Friery

Supported Techs : Impact

JPeMu is used to run machines originally manufactured by JPM or Crystal. Layout ZIP files must be unzipped, once downloaded, before they can be used with JPeMu. The following documentation assumes that you have installed JPeMu via a full installation of FMEIW (Fruit Machine Emulator Installation Wizard). If you have not used FMEIW then we recommend that you re-install all your emulators via this method as it will check your system for required files and will also set various parameters correctly.

Starting the Emulator

LEFT click the START menu and then choose the 'Programs' menu item (All programs on Windows XP). From the resulting menu LEFT click 'Fruit Machine Emulation' and then 'JPeMu - JPM Impact Emulator'.

The emulator will now load and you will be left with the screen below.

Browsing for Emulations

JPeMu contains a game manager which will scan a selected folder (and all sub-folders) for all compatible emulations. These will then be presented in a list within the game manager. Loading an emulation is then simply a matter of double-clicking the emulation name.

To browse a directory LEFT click the 3rd button on the toolbar to display the following screen :

LEFT click the directory into which you have unzipped your JPeMu layouts. Remember that each layout/emulation should be extracted into a different directory. These directories should be sub-directories of your main layout directory as in the example above.

When you are ready LEFT click the 'OK' button and JPeMu will scan the selected directory and all sub-directories.

The first time this process is run it can take a long time for JPeMu to scan all of the directories. The amount of time this takes when be dependant on the number of emulations you have in the directories and also the speed of your PC.

When the process has finished you will see a screen similar to the one below showing all of the emulations available.

Playing your Emulation

To run an emulation simply double click on the appropriate row in the Game Manager. All being well your emulation will now load and will begin to initialize. As the emulations are created from true fruit machine ROMs the emulation will go through the same initialisation routines as a proper fruit machine would.

After the intialisation has finished the emulation will be ready for play. At this point the emulation should be in 'attract' mode, indicated by the lamps on the machine flashing.

Inserting Coins

The method of inserting coins will depend on how the author has programmed the emulation. You therefore may need to try both of the following techniques :

Clicking the Coin Mechanism - Hover your mouse pointer over the coin mechanism (below). Clicking on the LEFT mouse button will usually insert a pound.

Use the keyboard - Using the keyboard it is usually possible to insert a pound by pressing the '0' (zero) key. The author may have set up other keys for different denominations, you will need to check the accompanying README file within the ZIP file for details of these.



Pressing the buttons

As with inserting coins the method for pressing the buttons will depend on how the author has programmed the emulation.

Clicking the buttons themselves - This is an easy one to test! After inserting some coins simply hover your mouse pointer over the START button for the machine and LEFT click it. If the reels spin then you will be able to press all of the buttons. Some people see this as the most authentic method of play. This is often referred to as 'mouse play'.

Use the keyboard - Keyboard play is possible with all emulations. After inserting coins use the keys below to play the machine. For non-standard buttons, ie, features, we would advise that you check any README file within the ZIP file for the emulation.

Spacebar - START

1 - Hold/Nudge 1st Reel

2 - Hold/Nudge 2nd Reel

3 - Hold/Nudge 3rd Reel

4 - Hold/Nudge 4th Reel (if applicable)

E - Exchange

C - Collect

` - Cancel



Configuration Settings

There are a couple of settings within JPeMu that can be adjusted :

Options

The DIP Switches will adjust the amount per play, Jackpot amount and whether cash pots on club machines are fixed at the Jackpot amount. The actual settings will differ from machine to machine so no advice can be given for how to set them. Make a note of the switch positions before you change them so that you can restore them in the event that your changes do not work correctly.

The Speed settings can either be set to 'Auto', where JPeMu will try to set an optimum speed, or set manually. If the emulation is running too fast then make the figure higher, if it is too slow make the figure lower. Do not make the figure too low otherwise this can prevent the emulation from running at all.
