@mitu I got my screenshot the way you suggested:

flip back to dtoverlay=vc4-fkms-v3d in /boot/config.txt use raspi2png

Thanks!

@zering just to be clear you are saying to remap in Emulation Station or Retroarch?

Is there any way to backup my current mapping?

I have a PlayStation 4 Dual Shock controller that seems to not have this issue with the same mapping. The one with the issue is a Vilros classic PlayStation controller with two analog sticks.

Thanks, all!
Cab is looking better and better...have issues with videos but that will be a different topic.

@spoofus https://retropie.org.uk/forum/topic/3/read-this-first

What exactly 'not working' means ? EmulationStation doesn't start ? Games aren't working ? Installation is not completing ?
Please add more details about your setup, including the Ubuntu version and hardware details.

@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.

@muldjord Thank you. I'll give that a go.

@dankcushions I think that's half the battle, the retroarch approach to mame inputs gets very confusing for users since there's no one size fits all solution. I find many users get lost in all the menus, saves, opt files, etc which are tangled with the inputs mame is expecting.

Adapter seems to be working great, tried out some more games over the weekend and I'm loving it so far. I was also able to map the table of hotkey combos (updated above), except the "Input State Slot Increase/Decrease" triggers at the same time that I go to Save or Load which is mapped to D-Pad right/left.

All retroarch.cfg:

input_state_slot_increase = "right" input_state_slot_decrease = "left"

N64 retroarch.cfg:

input_state_slot_decrease = "nul" input_state_slot_decrease_axis = "-3" input_state_slot_decrease_btn = "nul" input_state_slot_decrease_mbtn = "nul" input_state_slot_increase = "nul" input_state_slot_increase_axis = "+3" input_state_slot_increase_btn = "nul" input_state_slot_increase_mbtn = "nul"

-3 and +3 are C-Button left and right. If I set the All config to "nul", they won't work in any other emulator, correct? Should -3 and +3 be mapped to input_state_slot_increase/decrease instead of the ones with "_axis"?

@ajacks504 Hello ajacks504. Yes, I know this reply is almost 3 years old. I am having the same issue and just changed to "enabled" wherever it said "disabled" under mame. The next question is I do not have the line

input_player1_mouse_index = "0" underneath the device =" mouse line" anywhere

Is this something I need to add? I'm sorry I just don't understand all this. I'm not very computer savvy when changing the config stuff. I don't have a trackball yet but I have a spinner right now and I cannot get it to work or be recognized when playing tron. Thank you. hopefully this msg finds you

For anyone stumbling across this post, singe now running on RetroPie:

Specific install instructions here: https://retropie.org.uk/forum/post/252674

@wop99 Arcade ROMs are not to be unzipped - they don't work this way. Keep them zipped.

@umbongodrink not that i have the answer, but im getting the same thing with my port of Blood and Doom 3. i can get them to run fine, but when i exit. i also get a black screen and have to reboot.

heres to hoping someone can point to something on whats going on

@dtyler3 What is your version of retropie? Are any other modifications made to it? We need a little more info to help you, and a verbrose log would be very useful too.

Is your PI configured to boot from USB (not only from sdcard) ?
Check out the Pi 4 Boot Diagnostics page to determine that - look for the 'boot mode' configuration that is shown when you start and see if it includes USB.

@crush Yes I did that, didn't realise I had to do it twice. All sorted now :-)
