It is necessary to access the RGB-Pi file system in order to accomplish tasks such as adding '''ROMs''' and '''BIOSes'''. Access to the file system also makes it possible to save copies of your game list, favourites, save states, custom images, videos, music and skins among others. There are two different approaches to gaining access to the RGB-Pi file system:

It doesn't matter the way you access to the file system, you'll be always presented with the following basic schema:

You must change the integrated '''A'''

This is usually due to a short circuit in the '''B''' chips between ground and 5v, you can check it with a multimeter in continuity mode between the pins of the board corresponding to 5v and the pins of the buttons of player 1 and player 2, if any of these does continuity the integrated '''B''' must be replaced.

Check that the audio switch with which you can select if the output is mono or stereo is in the correct position for your wiring, if your wiring is standard jamma it should be in mono in the position of a single speaker, if your wiring is MVS Should it be in stereo in the two speaker position, prolonged use of the amplifier in the wrong mode could end up damaging the '''A''' chip and need to be replaced.

===Getting your RGB-Pi IP Network Address===
 
−
 
 
−
Before connecting from your PC to RGB-Pi OS, you need to know the IP address of the same. If you already plugged a network cable or configured a Wi-Fi connection, you should be able to get your IP from the Network menu:

[[File:sys_opt_network.png|border]]
 
−
 
 
−
===File transfer via Samba===
 
−
 
 
−
Samba is a free implementation of the SMB protocol, and allows other computers on the local network to access and transfer files to RGB-Pi OS.
 
−
 
 
−
Windows, OS X, and most Linux distributions should be able to navigate directly to RGB-Pi OS Samba share by entering '''\\RGB-Pi\''' into their file browsers. If you cannot reach the RGB-Pi OS file system by name, it may be possible to reach it by network IP. Once you have determined RGB-Pi OS IP, enter that address in the file browser instead of the name, i.e. '''\\192.168.1.43\'''
 
−
 
 
−
===File transfer via SFTP===
 
−
 
 
−
SFTP is a secure file transfer protocol that also allows other computers on the local network to access and transfer files to RGB-Pi OS. This method is faster than Samba transferring files.
 
−
 
 
−
The most extended 3rd party tools for accessing via SFTP are:
 
−
* [https://filezilla-project.org Filezilla]
 
−
* [https://winscp.net/eng/download.php WinSCP]
 
−
 
 
−
Use your RGB-Pi OS IP address and '''port 22''' to connect. The credentials are: username '''pi''' and password '''rgbpi'''
 
−
 
 
−
===Direct drive access===
 
−
 
 
−
This method consists of mounting the SD card on a host PC running Windows, Linux, or OS X.
 
−
 
 
−
====Access from a Linux host====
 
−
 
 
−
If you’re on Linux, you can simply mount your SD card by using any smart-card reader or USB adapted. This way, you don’t need network connection, and you can access all files on your drive.
 
−
 
 
−
====Access from a Windows host====
 
−
 
 
−
Accessing '''ext4''' partitions from windows is not supported natively but you can install a [https://www.howtogeek.com/112888/3-ways-to-access-your-linux-partitions-from-windows/ 3rd party driver] to achieve the same (we have not tested this method).
 
−
 
 
−
====Access from an OS X host====
 
−
 
 
−
Mac OS X does not allow users to mount '''ext4''' partitions natively but you can use one of the following programs:
 
−
* [https://www.paragon-software.com/home/extfs-mac/ Paragon’s ExtFS] which is paid software.
 
−
* [https://osxdaily.com/2014/03/20/mount-ext-linux-file-system-mac/ OSXFuse] which is a free software.
 
−
 
 
−
Please do note that '''we have not tested''' any of the two above solutions.
 
−
 
 
−
==Using an external USB drive==
 
−
 
 
−
RGB-Pi OS offers the possibility to store your ROMs, BIOSes, custom images, videos and all your game list information and favourites on an external USB drive.
 
−
 
 
−
Your USB drive must be formatted as FAT/FAT32. This is the most easy way of accessing to your files from any PC and also to move all your content from one Raspberry to another. Another good example is when for some reason, your RGB-Pi OS SD card gets corrupted. By using an external USB drive you could write a new copy of the system and plug your USB again.

In construction On this page you will find all the cases which ARE NOT COVERED BY THE WARRANTY for having misused the device, in order to be able to repair it yourself or take it to a local technical service.

Component Description

Jamma.png

  • A Audio amplifier - LM4952
  • B Controllers ICs - MCP23017
  • C Audio switch

Faults and solutions

I have connected the reverse board and now the controls do not work

Integrated circuits B are damaged and must be replaced

I have connected or disconnected the board with the machine turned on and if the audio amplifier has burned, I have no sound

You must change the integrated A

The raspberry does not turn on, none of its LEDs are not even red

This is usually due to a short circuit in the B chips between ground and 5v, you can check it with a multimeter in continuity mode between the pins of the board corresponding to 5v and the pins of the buttons of player 1 and player 2, if any of these does continuity the integrated B must be replaced.

Audio is very low or distorted

Check that the audio switch with which you can select if the output is mono or stereo is in the correct position for your wiring, if your wiring is standard jamma it should be in mono in the position of a single speaker, if your wiring is MVS Should it be in stereo in the two speaker position, prolonged use of the amplifier in the wrong mode could end up damaging the A chip and need to be replaced.
