Adding games to PRG App is as easy as putting the games into a folder and make PRG app scan it. Folders with games can be stored in the device’s own storage, cloud services like Dropbox or Google Drive and network area storage devices (NAS).
Please note that all users start with a trial period. Once the trial period finishes you will be restricted to only 6 games, you need to upgrade your user account with an Activation Code to remove this limitation.
There are three methods to add games to prg:
Any of the three methods are supported when using local storage (internal/USB/SD card) and remote storage like DropBox and Google Drive. Just keep in mind the following:
MAME is the only emulator that uses compressed files as input, all other emulators require the files to be uncompressed. PRG will scan and recognize your game files compressed with zip, 7zip and rar, but before starting the game, PRG must uncompress the game to run the emulator. The uncompression will take some time if the file is too large, and the uncompressed copy will be put in your internal storage.
So your options are:
The following is the list of supported file formats for each system. Your file can be stored inside a compressed file (.zip, .rar, .7z) according to the restrictions stated above.

When you add a single game PRG will scan the file and add it to the list. Once in the list it will stay permanent unless you remove it in the Game Details screen (the one that has the Play button). Note that you can always remove the file from the list, but PRG will not remove the file from your storage.
When you add s single folder PRG will scan it looking for games for the system that you selected. It will not scan the folder again unless you request it to. So if you add or remove games to that folder, you must request a rescan in Manage Games -> Manage Folders, then select the folder and use the option to rescan.
If you are using a PRG Collection you need to request a rescan the first time and every time you add or remove games on it. Use the option Manage Games -> Rescan.
A PRG Collection is a unified folder structure to organize your collection under an unique PRG folder at the root of any of your Android drives. This folder structure can be created through PRG itself, just go to Manage Games -> Manage folders, select the drive and the app will offer you to create or update your folder structure. In cases where Android forbids the app to write in your device, you can use a computer or an Android file manager to create the folders yourself.
In the example below taken from a Samsung device, you can see that PRG will look into the folders /sdcard/prg and /storage/extSdCard/prg :
Note: If you don’t see your drives here, some apps like ES Explorer take ownership on the drives, just close it, or unmount the drives from that app before opening prg

As an example, this is a valid folder structure for 5 Sega Genesis games. Two of them are uncompressed and three of them are compressed into one zip called moregames.zip
PRG will try to auto detect your games. If your game is detected, PRG will display the cover and screenshots of that game, it will also download any specific configuration that could be required to run that game. That configuration can be a special keyboard mapping, CPU emulation type, among others.
At first, PRG will try to detect your game using its name. The name will be converted to a standard code and that will be used to search into its games database. These are examples of that conversion:
Mega Turrican.smd -> megaturrican
Pole Position.atr -> poleposition
If the game is not detected by this automatic code, PRG will read the contents of the file to look for a specific id to search into the games database. Your game may be not recognized today, but the code is being improved as we advance the development and add more games to the database.
Commodore Amiga has games that require more than one disk, that means that you will have more than one file for each game.
For multi disk Amiga games, the game code is taken from the directory containing the game. For example this will be recognized as fireandice
MAME games depends directly on the version of the MAME emulator. To make things easy, PRG use four folders to look for games.
prg/mame/2001 MAME 0.37b
prg/mame/2003 MAME 0.78
prg/mame/2010 MAME 0.139
prg/mame/2014 MAME 0.159
Just put the .zip or .7z files on those folders. DON’T UNCOMPRESS THEM!
This is an example
Adding MAME games is not as simple as adding a console game
Just put the individual .zip or .7z files your fba folder. DON’T UNCOMPRESS THEM!
MSX has games that require more than one disk, that means that you will have more than one file for each game.
For multi disk games, the game code is taken from the directory containing the game. For example this will be recognized as golvellius2
Each ScummVM game is a collection of files inside a directory, they were originally MS-DOS games (or Amiga).
The name of the directory has to be the code that ScummVM define for each game
This is an example for the game Day of the Tentacle, with ScummVM code “tentacle”
