You have two computers using frontends compatible with those natively managed by ARRM, and you want to copy certain ROMs and their media/metadata from a source computer to a target computer by merging metadata into target gamelists

This tutorial will help you understand how to retrieve certain metadata and media from a system that has already been scraped and is located on another computer (source) in order to import them onto another computer (target) by merging metadata into target gamelists

• Create a folder (system) named, for example, “export” at the same level as the folders of the other systems.

• Launch ARRM

• Click on the heart icon and select the “export” system so that it appears in the system browser.

• Configure this new system using the “Edit Systems” button (you can Duplicate an existing system). Remember to specify the supported extensions.

In this example, I'm creating a blank system; I'm only specifying the extensions. This system will never be scraped; there's no need to fill in the rest.

• Navigate to the source system from which you want to retrieve metadata (here, astrocade) and click the “Display” button to display the ROMs in the ARRM database.

• Select the ROMs to copy and click the “Move/Copy to folder” button in the “Roms Selected” tab.

• Check “Copy ROMs”

• Select the “Export” folder and click “OK”

• Confirm the operation by clicking “Yes”

• The “export” folder contains the ROMs, their media, and their metadata.

• Copy this “Export” folder and paste it onto your destination computer in the same directory as the folders on the other systems.

• Paste the “Export” folder from the source computer.

• Launch ARRM

• Click on the heart icon and select the “export” system so that it appears in the browser. System

• Configure this new system using the “Edit Systems” button (you can duplicate an existing system). Remember to specify the supported extensions.

In this example, I'm creating a blank system; I'm only specifying the extensions. This system will never be scraped; there's no need to fill in the rest.

• Navigate to the “export” system and click the “Display” button to display the ROMs in the ARRM Database.

• Select the ROMs to copy and click “Move/Copy to folder” in the “Roms Selected” tab.

• Check “Copy ROMs”

• Select the destination system (here Astrocade) and click “OK”

• Accept the operation by clicking “Yes”

• In the “Astrocade” folder, the ROMs and media are copied, and the metadata data is merged with the existing game list presents

    <desc>In this two player game each player controls an artillery gun set in a mountain landscape with the goal of destroying the other player. Players take turns firing at each other; on each turn you have a limited amount of time in which the barrel angle and powder level can be set in order to control the direction and distance of the shot. When deciding on your shot, you will need to take the current conditions into account, which includes wind speed/direction and any mountains that may get in your way. Successfully destroying your opponents gun will earn you a point, and the first player to reach the set number of points wins the game. There are multiple skill levels available which set the amount of time you have to make a shot.</desc>

    <desc>Dans ce jeu, chaque joueur contrôle un canon d'artillerie dans le but de détruire l'autre joueur. Les joueurs se tirent dessus à tour de rôle; à chaque tour, vous disposez d'un temps limité pour régler l'angle du canon et la puissance du tir. Lorsque vous décidez de tirer, vous devrez tenir compte des conditions actuelles, notamment de la vitesse/direction du vent et des montagnes susceptibles de vous gêner. Détruire avec succès l'arme de votre adversaire vous rapportera un point, et le premier joueur à atteindre le nombre de points défini remporte la partie. Il existe plusieurs niveaux de compétence disponibles qui définissent le temps dont vous disposez pour effectuer un tir.</desc>

    <name>Bally Pin</name>
    <desc>Bally Pin est un jeu de flipper comportant deux tables différentes. Le jeu se joue avec deux joysticks, l'un contrôlant les deux batteurs de gauche et l'autre contrôlant les deux de droite. Le jeu peut être joué par jusqu'à quatre joueurs qui se relaient jusqu'à ce que tous les joueurs aient utilisé leurs cinq balles. Le but est simple: obtenir le meilleur score. Les deux tables sont similaires mais avec des dispositions légèrement différentes et les deux comportent six pare-chocs (éclairés ou éteints), des cibles tombantes, des cibles de kick supérieures et un spinner. La balle est censée réagir comme une vraie balle le ferait lorsqu'elle est frappée par un batteurs, la vitesse et l'angle de celle-ci étant affectés par l'endroit où elle est frappée sur le batteurs.</desc>
