Does anyone tried to run lgpt on pi boy? https://fr.aliexpress.com/item/33003964785.html

It has usb port so normally i should be able to send midi with my usb to midi cable (what i successfully do on my normal raspberry pi )

I think it should work but I don’t find on internet if retropie (pi boy’s os) can run application like lgpt instead of roms. If not do you think that raspbian can be running on pi boy? With screen working and buttons reacting like it was a gamepad controller

I also looked for gamepi43. Same questions...

Or if you have other devices suggesting me i’m ok.

My actual raspberry pi start automatically lgpt and i use it with gamepad. That’s cool but something with integrated screen + buttons + battery should be even more cool :-)

So your link works on computer

It's seems to be more like a GPI case than a pi boy because pi boy has 6 buttons. Normally Gpi case is with a pi zero and pi boy is with raspberry pi. I didn't see usb port on GPI case (that mean that lgpt midi can't work on it) that's why I am more searching a pi boy.

But he definitly has something plugged on the right side of the "gameboy", and on Gpi case you are not suppose to be able to do that. So maybe it's another one which I don't know.

But seeing that it works with the one he has is encourageous of it can work on something like this

yea this is not the piboy, he says what he used in another post on that account - and he is using midi i/0 with it.

I would probably try to mod one of these commercial ones to support hardware midi out rather than use a USB device:

and you can do a trs midi jack type connector

By watching his other post I discover he added this : https://www.gotronic.fr/art-hub-4-usb-zero4u-29439.htm

maybe it was a Gpi case at beginning. I didn't know this can be done. With pi boy it's more expensive but you have already a usb port

Thank's for the link about midiPi. I prefer for now keep using the usb to midi cable because it's more little, and it actually works since a longer time than my midi cables wich become broke relatively quickly.

I use that : https://www.thomann.de/fr/thomann_midi_usb_1x1.htm

Not exactly this one but it's close. I used that usb midi cable in my video with piggy controlling megadrive 1. This video :

I think the gba cm3 might be the best route here : https://www.freeplaytech.com/product/fr … 3-diy-kit/

It has a single usb you can use for midi or midi audio with a class compliant sound card.

The device herr_prof linked on Instagram is a Kites Circuit Sword (RPi CM3). MIDI output is by using an Arduinoboy.

So I finally received my pi boy. It launch retropie at start with emulation station and don't have raspbian.

I added lgpt folder in home/pi. On retropie if I go in options, there is a file manager and I try to launch lgpt from there. It don't work i have black screen I don't know why...

I saw on internet there is the "ports" possibility for non-emulation file by adding file.sh in a specific folder. I have to test that

I'm able to start lgpt on pi boy in the ports section of retropie's emulation station. The operation with other pi handheld or pie retropie should be the same. My actual problems are :

1) emulation station sometimes don't start but maybe that's because of bad shutdown programs. Normally we need to close emulation station from menu before shutdown the gameboy.

2) for now I can't use buttons correctly, they are crazy mapped from my mapping.xml file (if no file they don't work at all) which is complicated is that I can't see the terminal (or don't know how) and so can't use lgpt key display option. Pi boy doesn't have raspbian only retropie and don't know how access to the terminal from it... With a keyboard connected and using it, it works fine

You cant ssh into it?

@herr_prof no there is no ethernet port.

But I finally get it working, (but there is a problem about audio) it seems that it doesn't like when changing stuff on the sd card. I "finished" an important part of my setup, used it like 4/5 times and emulation station always started now. If someone has a pi boy, you must exist lgpt then press start on emulation station then choose system shutdown. If you don't it can corrupt files and don't start again...

And I discover how accessing terminal too. If you choose quit emulation station insead of system shutdown, you arrive to a terminal! And there mapping is easyer because a log is created (have to use mapping event print option with lgpt command in lgpt wiki). You just need to remember which button you press before open the log (with cat lgpt.log for exemple). And doing that I saw that lgpt was good launched from the terminal so if I use only lgpt maybe I will just automatically start it and don't launch emulation station like I did on my standard raspberry pi.

So now it's good mapped and midi works good! BUT, the sound of lgpt is very dirty. It sounds like a problem other people already had here. The thing strange is that sound is fine in other emulation games.

Other points :

- the shoulder buttons behind the pi boy are not good when you put the gameboy on a table because the buttons are pressed, I think it can ruin it in the time, keeping them always pressed...

- screen with lgpt is small, it's fullscreen but lgpt has a yellow part unused around the program, that should be much better to zoom in a bit but I don't know if it's possible. It's a little hard for eyes for me

ah my point is that if you find a way to hook up internet over USB or wifi then you can ssh into the pi, run piggy and see the button presses in your shell while viewing the UI on the pi boy.

Ah ok herr_prof nice idea i have usb to ethernet adaptor so it should work (no wifi here)

But right now my problem is dirty audio in lgpt. I see in other threads that the principal solution was external usb audio interface. But maybe it's outdated because audio works good on my other raspi without usb interface and i would prefer much without

Maybe i should create a new thread for that because it's related to rasppi not specific to pi boy. The audio problem is on a pi3b (which is inside pi boy)

i think the onboad audio is probally still not cd quality, it depends on what the piboy dev is using,

With my other pi, I found the quality of audio pretty ok! I used it here (there is also genesis but you can easy know what is what) :
https://www.youtube.com/watch?v=3D4FZJC … el=MazHoot

So maybe this pi boy 3b+ pi can also do it? I don't know what is the version of my other pi...
