thanks for the help :)

@haller Thanks for sharing your solution for others.

This would be possible if you check presence of OMXPlayer process. It's not an elegant method but it might work. But keep in mind you will loose opportunity to play video snapshots in gamelist

So the better way would be an implementation into the C++ code of ES itslef.

PSEUDOCODE

#!/bin/bash # Run this script with root user or sudo command # Initiate GPIO x ouput # Exports pin to userspace echo x > /sys/class/gpio/export # Sets pin x as an output echo out > /sys/class/gpio/gpiox/direction while true do # Slow down the whole thing a bit sleep 5 # Suggest running oxmplayer instance omxpid=$(pgrep omxplayer) # Set GPIO x high > switch off screen [[ -n $omxpid ]] && echo "1" > /sys/class/gpio/gpiox/value # Set GPIO x low > switch on screen [[ -z $omxpid ]] && echo "0" > /sys/class/gpio/gpiox/value done

@carcamerarig Yip just run emulationstation to launch and then exit through the menu it will drop you back to the console.

@caver01 I'm working on it, now for some reason I can't click buttons in the menu of rgui :(

It seems that you should be able to use the linux way by being in developer mode, opening crosh, and typing shell.
You then will have a bash shell, with the dd command.
Careful to use the correct device as target for dd.

I also see that the chromebook recovery utility can be used too - see here : https://www.reddit.com/r/chromeos/comments/7d02im/using_a_chromebook_to_install_an_iso_to_a_usb/

@mitu said in How to port games to retropie:

the game needs to either compatible with Linux or supported by one of the Emulators/Ports included in Retropie

And the source code needs to be available and some sort of genius needs to Port it from Windows to Linux. Sonic mania: not a chance

@cpcbegin no x server, no vnc.

thanks i will use the official image - thank you

Here's a solution for the Linux command line of Retropie. You get to the command line by quitting Emulation Station or by connecting over the network with ssh. After logging in, you will be in the home folder of the user pi with the full directory path /home/pi/ or in short ~.

I've extracted all rom names from the 0.78u5 DAT file. You can get the list here. Save it into a file called lr-lite.list to use it with the following commands.

In the example below, your full romset is in folder romset_full and the custom romset will be in folder romset_lr-lite, both located in your home folder ~. The file lr-lite.list is also in your home folder ~.

You'll then have to execute one these commands:

Either copy the files (needs more space, the full set remains intact)

while read file; do cp "romset_full/$file".zip romset_lr-lite/; done < lr-lite.list

or move the files (same space as before, filtered files are removed from the full set)

while read file; do mv "romset_full/$file".zip romset_lr-lite/; done < lr-lite.list

Now, you have a custom romset matching the 0.78u5 DAT file in the folder romset_lr-lite. Copy the roms into the rom folder of your choice (e.g. mame-libretro) and then scrape them to generate a new gamelist.xml.

You can delete the file lr-lite.list after checking that everything worked as planned.

Bonus for advanced users: I extracted the rom names from the 0.78u5 DAT file by using this command.

xmlstarlet sel -T -t -m /datafile/game/@name -v . -n mame2003-lr-lite.xml >lr-lite.list

@nextria I'd say dodgy LAN port or cable then.

Thank you :)

@mitu That did the trick!! Thank you so much for the assistance!

I would recommend not buying anything from this company, they use our work on emulators for commercial use, which is forbidden by the license of those emulators. Also, their products are known for being pretty bad quality.

@retrocake said in Explaination of rom hierarchy in FBA DAT file:

Why can't I just do this?

cp original_roms/*.zip roms/ grep cloneof FB\ Alpha\ v0.2.97.42\ \(ClrMame\ Pro\ XML\).dat | sed -rn 's/.* name="([a-z0-9]+)" .*/\1/p' >> remove_roms.txt grep neogeo FB\ Alpha\ v0.2.97.42\ \(ClrMame\ Pro\ XML\).dat | sed -rn 's/.* name="([a-z0-9]+)" .*/\1/p' >> remove_roms.txt for file in `cat remove_roms.txt`; do rm roms/$file.zip;done;

Yes, it would remove clones and neogeo games. If you search on this forum, i think you can also find a list of clones worth keeping (i kinda remember seeing topics about this).
Also, it is worth mentioning sometimes parent roms are marked as NW (non working) and are in the romset only to allow their clones to work
Actually, if you want to write your own script to filter games out, i would recommend writing something that parse https://github.com/libretro/fbalpha/blob/master/gamelist.txt since the NW information is present.

Map the buttons you have and then hold a button or direction on any item you wish to skip. If it says already assigned, you aren't holding it long enough as it is registering a button press.

With my arcade controller, I have found you can use the dpad to skip by holding up or down alternating on each item I wish to skip.

@megafacehead You might try Attract mode for this, it seems to be supported.

Forget it. Got it. Rebooting let me get into emulation station. Oddly keyboard would not work until after I set up a usb game pad. All set thx.
