@dankcushions thank you for your suggestions and you're right. I've tried to change the gpu_mem but it still crash, just after a different number of exiting game.

So if there's no solution I tried a workaround, hope this could be useful to someone else. Not using Omxplayer I had that problem with some video preview that got sound but not video. As I told you before I noticed the problem was the codec profile. The lucky thing is that on W10 the thumbnails of videos (associated to VLC program) that have this issue show the VLC icon instead of the screenshot preview of the video so they were easily recognizable. I used a program (WinXHDVideoConverterDeluxe) to convert manually those videos (they were more than one thousand but the program runs fast e you can upload and launch them all togheter and just wait, the only boring thing was to select them all manually). I replaced the codec profile corrected videos and everything works fine. I made two tests of almost 4 hours and exactly 250 exiting game (but who counts, I'm going crazy, I know) each one and the issue didn't occurred.

The only thing that I noticed is that shutting down the system it took about 20 seconds of black screen before starting the power off process, technically why? Did I stress to much the system? And what do you thing, should I expect another crash somehow or maybe I'm safe?

Thank you so much.

@Hex @mitu For me, the power saving mode was disabled by default on 4.6.1 on a Pi4, I turned it on to Enhanced and the CPU usage dropped instantly to 0.3 as before. Maybe it needs to be reactivated by default?
Thanks for the explanation!

I too am experiencing the same issue. The game works perfectly in DOSbox on my PC and I'm using the exact same files and, from what I can see, the same DOSbox config options but through Retropie it crashes as described above.

My Raspberry Pi is a 3B+ as well.

@mitu thanks i needed to add Pokemon Mini and Odyssey 2 since that is the only systems that are not in my emulation station but is on RetroArch. i ended up kinda getting my favorites problem solved. i just told it to only show my favorites and it showed the (USA, Japan, ect)

This is what I did.

@abispac This can be achieved by using the new favorites menu. You just need to be using a theme that's supports it...

@quicksilver thanks, really appreciate that you found it useful.

@rbaker The first time I tried, I did follow that link exactly. After that didn't work and I started over a number of times trying it over and over, in the Retropie menu on Emulationstation there is a Basic Install option that says it will automatically add all the core and main emulators, so I did that instead of Manage Packages, to try and save a step as I had been trying for hours. I reinstalled the Image several times to try from the beginning. Each time the initial boot up seemed like it was going correctly based on the videos I watched and instructions from wiki.

The emulators I'm most interested in trying for starters are NES, SNES and SG/Megadrive

Yes, I did configure a controller during the first boot process. I followed this https://github.com/RetroPie/RetroPie-Setup/wiki/First-Installation#installation up to transferring roms from USB...the final instruction says to "Refresh Emulationstation by choosing Restart Emulationstation from the start menu" After doing so, I could never get ES to start back up. I tried to not do the restart a couple of times, but nothing happened. There were no emulators or roms I could see or access.

@tronkyfran Thanks a lot for the super detailed support !
I made a "powder coated" texture so at first I'll try with UV mapping the cartridge.

Yes, black (or white) background already considered for creation of transparent images to be used in ES themes.

Especially useful also your tips on environment and reflections: I have zero knowledge in that area.

Thanks again!

@synack thanks !! Will try asap.

@edmaul69 , Thanks for that. At least there is some solution, maybe when I get more comfortable with linux and retropie i'll compile the kernel.

I've followed the instructions but I've got another problem. I can't see all systems emulator not only the ports.

@UDb23 yeah it's a little hidden in the wiki, perhaps I'll make it a little more verbose:
