I tried different things, the manual of everdrive says that :

"SRAM backup: This function allow automatic backup of SRAM save data to SD card. Every
time when user changes the game, the OS will make write a file in MEGA/SAVE/ folder, the file
name will match to ROM name"

I don't have this option when i goes in options from C menu after booting everdrive. Maybe I need update the OS? It's not activated in my case because if I turn off megadrive with MD tracker (I tried also with RESET) and back on, it always start empty.

In MEGA/SAVE, I have this file : MD TRACKER 0_13b.srm so it is suppose to works? (I don't know if it's sram file or save state file, it can be old save state one) but it don't work. Maybe a problems about rights? I will try "sudo chmod 777" on this folder and files

And if I open the in game menu ("START + DOWN") in "options" if I goes in "toolbox" I can select copy from ram to sd or copy from sd to ram. I tried do that but it does not work.

In my tests, I also discover that the undiscontinuated sound when stopping tracker, will finally stop after a few minutes.

Ok thank's for your precisions. I'm sorry if I don't understand all, when it becomes english + technical stuff (i'm french), it started to being hard to understand but I think I get it.

I don't prefer save state than standard way, I think standard way is more confortable, like saving on lsdj or on lgpt. I was just searching an other way to save because I couldn't find a standard way on your tracker. But if you plan to implement that, that's much cooler!

Keep the great work and happy new years :-)

Edit : just for know, my tests are with everdrive x7

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 :
https://www.youtube.com/watch?v=3D4FZJC … el=MazHoot

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

Your link doesn't work (from phone) i will try on computer tomorow

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 :-)

I think i never spoke about my music on this forum. So, this is my actually most chiptune album. A lot of chiptune but not only.

There is also didgeridoo, accordion, jew's harp, flute... and voices! Voices from me + a friend.

The list of chiptune software and hardware I used for this album is in the mini book (don't know english word for "livret"). Texts are in french.

It's my only album which has physical support (cd) + mini book and artwork for now. It is chiptune, tribal and industrial/experimental music

I get all the most things working right, but I hear a small latency with midi. I use LGPT to drive genMDM (awesome!!) additionnaly with LGPT samples and the sound of sega genesis is a little too late (microseconds) compare to LGPT samples. I use audio output of raspberry pi because I can't get my UR242 soundcard working and because sound is ok for me. I use usb to midi cable for drive genMDM.

I saw on LGPT wiki this :

"MIDI Configuration

This setting is also W32 only. It can be use to delay the output of midi by a certain amount of milliseconds. For example, to delay it of 1 msecs:

<CONFIG>
  <MIDIDELAY value='1'/>
</CONFIG>

also note: Because MIDI on PC is a bitch to synchronise and that the ONLY system that kind of worked was, surprisingly, the old MMSYSTEM audio system, I've re-enabled it as an option. So, if you need good midi sync or good timing, you will NEED to use this. The latency isn't great but in our case it's not a problem. To enable the old ass audio system and enjoy pretty stable midi out, add an entry in the config.xml with <AUDIOAPI value='MMSYSTEM' />
"

This should work only on windows right? Not on pi... and even if it worked, I don't want to delay midi, I want to delay sample for it sounds at the same time as midi.

But I tried MIDIDELAY value="2" for see, I didn't notice any difference. I didn't tried MMSYSTEM because I understood that it's for sync and I don't want to sync anything it's only midi out notes, CCs and samples

For me that's really the ultimate config, and I will defintly use again genMDM with LGPT! (on lsdj it worked but it was too complicated)

Everything seems ok in BlastEm.. (Or I've fixed this bug already?... big_smile)
I dont have any everdrives to test on hardware right now. And the only console I have is Nomad.

The square sound bug is only on megadrive (i tested on megadrive 1). On emulator I didn't tried with Blastem but in gen's (linux) and picodrive (rg350) all works good :-)

I think everdrive are still available I bought my just a few weeks ago. Maybe you can try on Nomad and there is megadrives / sega genesis for 30€ in my cash express hehe. Your tracker is too awesome for not be tested on real hardware! Lol

All the song data is written drectly into SRAM. It should save and load automatically the same way as it works with games that use battery for saves.
Do not use everdrive save states, thats completely different thing.

The only guaranteed way right now is BlastEm emulator. Others simply does not support both even and odd writes into SRAM, and typically restricted to 32kb.

So it means that there is no way to save on real megadrive / sega genesis with everdrive? Why save state shouldn't work? Because it's bigger than 32kb? As an exemple on Blasttracker everdrive's save state works great. It's a working megadrive tracker but which is really hard (mad) to use .

I have found an other USB controller I had somewhere, but it's nes style, dpad, select, start, A and B, no shoulder.

I tried to map both shoulder left and right to select, and it works for the page, I can go everywhere except quitting project screen, but I can't do copy operations like select+b in LSDJ (shoulder L + b in LGPT)

So it means that only shoulder right works, i can't mapp select to both shoulder right and left, only the first assignation will work
That should be better if select could do the job like on LSDJ. I think maybe it's that because it was created for consoles which don't have select at good position, but maybe this can be also changed? Maybe have to compile lgpt for that...

So I think I will just try with other controllers (have to buy new...) until it works good. One with no joystick but Dpad and shoulders should be a good candidate.

Hello (after 6 years... but I have exactly the same problem).

The joystick react but I think my controller is a little ruined and it's hard to use lgpt with it as cursor goes sometimes to right instead of down etc because you have to be very specific. For the D-pad, that should be better but...
I have that :

LOG: hat(0)::0=8
LOG: hat(0)::0=0
LOG: hat(0)::0=4
LOG: hat(0)::0=0
LOG: hat(0)::0=2
LOG: hat(0)::0=0
LOG: hat(0)::0=1
LOG: hat(0)::0=0

So I tried hat:0:0:1 like egr said in this post but it don't work for me. There is the "=" which was not on egr's controller.

"I hate linux" hahaha... I work on it every day hehe

I have my response! with help of raspberry community : https://www.raspberrypi.org/forums/view … 7#p1780427

I just had to remove the "exec" word and it works.

#!/bin/sh
cd /home/pi/Desktop/lgpt/lgpt_DEB/bin
sudo ./lgpt.rpi-exe
sudo shutdown -h now

I think it should work also without sudo in my case.
I made a video just for fun when I was happy with midi working on lgpt :

at the end you can see the screen size which should be better if it was a little bit biger. I wait the rca video cable for test with it. Normally i'm on the lowest resolution, and if I use the x2 trick in config.xml, it's bigger than the tv and display don't work.

The strange thing is that the two commands works, but not if the both are here.

If I only shudown in shell script, removing the exec lgpt command, then it boot and shutdown, but if there is the exec command of lgpt just before, then it start lgpt automatically at startup, but it not shutdown when I close lgpt and it just back me to the desktop. It seems that shell doesn't understand that I quit lgpt?

I also tried with python script for close, and with exec sudo but it's the same :

pig.sh

#!/bin/sh
cd /home/pi/Desktop/lgpt/lgpt_DEB/bin
exec sudo ./lgpt.rpi-exe
cd /home/pi/.config/lxsession/LXDE-pi
sudo python shut.py

shut.py

#!/usr/bin/env python3

from subprocess import call
call("sudo shutdown -h now", shell=True)

Now i'm using a .sh file like you where lgpt is successfuly started and where it's suppose to close after lgpt quit but it's not working I tryed

sudo shutdown -h now
sudo halt
sudo poweroff

none of that works

Oh ok! I thought if I did that it would shutdown piggy just after it started. For my part I placed the command directly in autostart file which is like this :

@lxpanel --profile LXDE-pi
@pcmanfm --desktop --profile LXDE-pi
@xscreensaver -no-splash
@point-rpi
@./Desktop/lgpt/lgpt_DEB/bin/lgpt.rpi-exe

so I can add @shutdown -h now at the end? I will try that

For the screen width, according to the cash express close to my house, this video rca cable doesn't exist haha... I have to buy it on internet... the x2 option in config.xml don't work if it's enable piggy boot only in window and it's bigger than the screen size... Maybe this cable will be the solution, I hope. If not, it's playable like that, not optimum but ok.

EDIT : hum... that's what I thought I tested what I said and it just close raspi after piggy started... I have to try with an .sh file like what you did

I sucessfully start lgpt when starting raspberry pi with placing a command in /.config/lxsession/LXDE-pi/autostart

But how I can shutdown automatically rapspberry pi after quitting Lgpt?
