This repository offers a bash script to build an installer from the files of the official RetroArch distribution for the different variants of the Anbernic RG350 and RG280 consoles. The generated OPK will install the RetroArch framework files in their precise locations, to which it will add a series of independent OPK launchers or wrappers for the different cores, so as to facilitate the integration of RetroArch in frontends such as GMenu2X or SimpleMenu.

Installed RetroArch cores

In addition to the cores from the official distribution, the script also includes the cores compiled by the user Poligraf. Its repository is integrated as a git submodule of this one.

Below is the full list of cores that are included in the final generated OPK installers:

OPKs parameterization

The OPKs to launch the different cores are automatically generated from the configuration made in a CSV file. A couple of sample CSV files are included in the repository. One with the parameterization of the OPKs corresponding to the official cores (official.csv) and another for the cores compiled by Poligraf (poligraf.csv).

WARNING: The CSV file uses a pipe (|) as a column separator, not a comma (,). The first row of the file is ignored, so it can be used to identify the columns. The file must contain 8 columns in the following order and meaning:

1. Label that will be displayed by GMenu2X. For example Nintendo GB.
2. OPK filename without the OPK extension. The string retroarch_rg350_ will prepend the filename. For example, if in this column we put GB, the resulting OPK filename will be retroarch_rg350_GB.opk.
3. Name of the PNG file (without extension) that will be used as the icon in the OPK. The corresponding icon must exist in the icons subdirectory of the repository. For example, if we put gb in this column, we must make sure that the icons/gb.png file exists, which will be copied into the OPK during the installer building process.
4. In this column we indicate with true or false if the generated OPK will show the file explorer to select the ROM or game file when launched from GMenu2X. It will correspond to the column Need files in the table from the previous paragraph. Normally this column is true except in cores that correspond to game ports like Mr.Boom.
5. Filename corresponding to the RA core to be used (with the extension .so included in this case). For example gambatte_libretro.so. We will take it from the Core column of the table from the previous paragraph.
6. Core descriptor. It is used to differentiate between different launchers based on the same system. For example to distinguish the GenesisPlus and Picodrive cores of the SEGA MD system.
7. Extensions supported by the core separated by commas (,). These extensions are the ones that will be filtered by GMenu2X when displaying the file explorer (only works on ROGUE). They should match or be a subset of those indicated in the Supported extensions column of the table in the previous paragraph. For example for normal Game Boy (not color) we will put gb, gz, zip, 7z.
8. Directory where the system ROMs are located. It will be the one shown by default when opening the OPK with GMenu2X. For example /media/sdcard/roms/GB/.

Script usage

The script is designed to be used on Linux with bash. The procedure to use it is as follows:

1. Install some requirements:

   $ sudo apt install git wget p7zip-full tar sed squashfs-tools

2. Download repository with submodules (IMPORTANT don't forget the --recurse-submodules option):

   $ git clone --recurse-submodules https://github.com/eduardofilo/RG350_auto_ra_installer.git

3. Create the CSV file with the parameterization that we like. We can use as template one of the two files included as an example in the repository (official.csv and poligraf.csv). It is important to bear in mind that the column separator is a pipe (|) and not a comma (,) as usual in this kind of files.

4. Set the parameter CONF_CSV at the beginning of the script with the name of the previous CSV file (without extension).

5. Put the date of the RetroArch distribution from which you want to build the installer in the v file. Naturally if the date is in the future, the script will fail.

6. Execute the script:

   $ cd RG350_auto_ra_installer
   $ ./build.sh

As a result of the execution (and if there are no errors), two files will appear in the releases directory, one to be used in stock/ROGUE systems and the other for OD Beta (unless we have disabled the generation of any of them by means of the BUILD_STOCK and/or BUILD_ODBETA parameters at the beginning of the script).

Built OPKs usage

When launched, it asks for two options that are disabled by default:

• Uninstall previous wrappers: Remove OPK launchers (wrappers) installed previously.
• Install config: To install basic configurations for most cores (basically the ones collected by RetroGameCorps in their guide). The recommendation is to install the configurations the first time and not to install them in subsequent installations to avoid losing the personal settings made on it.

Options are marked by selecting them with the Up/Down controls and pressing X. To install, select the <OK> button with the Left/Right controls and press Start. For some reason, the program starts with a black screen on OD Beta. Press any of the directional controls to make the screen light up.

The OPK with the installer can be obtained in the releases of this repository.

Hotkeys

If the Install config option defined above is used, among other things like video settings for most cores, the following controls will be adjusted globally:

Function	Shortcut
Pause	Select + A
Reset	Select + B
RetroArch menu	Select + X
Fast forward	Select + Y
Save savestate	Select + R1
Load savestate	Select + L1
Swap disk	Select + R2
Open CD tray	Select + L2
Exit game	Select + Start
Change savestate slot	Select + ←→
Change volume	Select + ↑↓
