Yes, that was my question at the beginning. I asked how can I install something from that repository. What commands should I use from the Retropie, to install beebem. Can you please help me, because I am a noob?

@lostless Thanks. I am thinking of cutting an old gba cartridge to fill the space left at the top.

Just a quick update. The Steamlink script module was a great help in both the minimal window manager as well as installing Ports.

Thank you! My questions have been answered.

Isn't it cleaner to use systemd / services in order to do so ?

It is explained here how to cycle between 2 services:
https://forum.kodi.tv/showthread.php?tid=288584

For kodi.service (configured as a user service not system wide service contrary to the above link) :

[unit] ... Conflicts = emulstation.service ... [service] ... ExecStopPost = /usr/bin/systemctl --user start emulstation.service ...

And for emulstation.service

[unit] ... Conflicts = kodi.service ... [service] ... ExecStopPost = /usr/bin/systemctl --user start kodi.service ...

Emulstation and kodi should not be services enabled/start by default at boot but rather
autostart.sh start the first service by something like:

systmctl --user start kodi.service

if kodi is configured to be the first one.

To go further we can also think about replacing the autostart script by a retropie service which is enabled at boot time. At start, it launches the first configured service. At stop it ensures that emulstation and kodi are stoped.

If the service is run as pi user (which is more secure), the pi user must be lingered to enable autostart of the service at boot even if the user is not logged in.

loginctl enable-linger pi systemctl --user enable retropie

Advantages:

All the services could be controlled, inspected, logged through the systemd tools Not need for automatic login It could be easily extended to any number of services not just 2.

@MeltedPineapple you'll have to do the research on how to set that up. I haven't attempted it myself, I'm waiting for my Sinden Lightgun.

Been playing around and yes it does play quite nicely these days. Its been a while since I tried snaps on Pi0's, I think last time I did try it omxplayer caused some weird overlapping issues.

I've managed to get the size down quite a bit. I could probably increase a little as the video file sizes are typically smaller than the boxart! I've settled on 320x240, no sound and 10 seconds. Looks fine on the small screen, usually 10 seconds is enough to get an idea of what the game is like, and the sound can sometimes be a little rough so not an issue losing that. Also limited to 30fps as a lot were 60.

I used ffmpeg with commands: -i input.mp4 -r 30 -s 320x240 -ss 0 -to 10 -an output.mp4

mkdir trimmed for %%a in ("*.mp4") do "d:\ffmpeg\ffmpeg" -i "%%a" -r 30 -s 320x240 -ss 0 -to 10 -an "trimmed\%%a" pause

Created a little batch file and it does them pretty quickly.

Filesizes massively reduced, one collection was 572 games. scraped videos took 1.99GB! trimmed versions took just 137MB

I'm glad I asked a silly question now :)

Thanks again for doing this!

You'll have to use something like xboxdrv maybe. I haven't gotten around to doing it myself yet.

For those of you looking for an easy way to install the libretro core, I've created a script in RetroPie-Extra for it: https://raw.githubusercontent.com/zerojay/RetroPie-Extra/master/scriptmodules/libretrocores/lr-freej2me.sh

Some of the first games I ever worked on were these J2ME games and it's been fun to play them again a bit.

true but some people don't know how to create a .sh as I've said I don't know how this should be in implemented but it would be nice to be able to see your achievements when you're hovering over the game in ES

@Cooloring if on a pi 3, disable overscan on /boot/config.txt.

If on a pi 4, doesn't work with omxplayer because of different video handling. Use VLC for screensaver.

You may choose to use VLC for screensaver on the pi 3 as well, but performance isn't great.

Try to see if the program doesn't search the current folder for the file needed. This way, you can cd to the game's folder and run it from there.

Actually it turns out that evhz gets seriously confused with a HID composite device mouse+joystick sending data at high rates. sometimes I read actual values, sometimes very slow updates

I can find many mouse rate tester apps, but nothing for USB joysticks. Does anyone know of a utility for joysticks similar to mouserate?

@HipsterDuRocher Thanks for the offer. We wouldn't be able to link anything in with subscribers as I can't share any data with external sites.

Not sure what you had in mind, but even if it was possible I lack free time to do any sort of collaborative work. Sorry.

But wish you all the best with your site and thanks for your efforts.

@theburgerking said in Integrating lr-mess quasi-cores into RetroPie-Setup:

Is there an lr-mame core? Could I build one? I have used lr-mess both prebuilt and built from source and I see from its build script that it just pulls from https://github.com/libretro/mame.git.

Yes. Both lr-mess and lr-mame are built from the same codebase you mentioned (forked upstream MAME), but with different build options, which results in different supported systems (arcade vs. non-arcade).
I was referring to MAME (the upstream project), not the libretro cores.

Does this mean that mame itself is the part of the mame distribution that can run that system?

Upstream MAME distributes only 1 binary which supports all systems included - either arcade, computer, mechanical, etc. There's no separate MESS anymore and I think hasn't been for quite some time.
