Playing with the sourcecode, I usurped the 8:7 PAR to be just 8:7 like 4:3. The switch that controls this is a boolean and I haven't the time to change it right now (and then I would need to make a github account to request a pull for the changes).

I realized I can use my USB2-A meter to test the output from the USB2 ports. Problematic PSU causes it to have 5.3V and the better one has 5.1V. Hopefully it helps anyone else having problems with a stronger PSU.

@Mikeymac02 All I did in my cabinet was run the power coming in through a toggle switch first then to a outlet inside the cabinet. Then I just plugged in a good surge protector to my switched outlet to power everything. To turn on just flip the toggle switch and it boots up. To turn off, properly shutdown retropie from the menu then flip the toggle switch to kill everything else.

@NewAtThis Can you try updating the ti99sim emulator from source and check again if the resolution handling is better ? It's been updated to the latest version, which was a major update.
Try to remove any video mode set through the runcommand launch menu.

@mitu This was it! I have a script that controls an LED light/Power button on my case, (as well as shows heat/fan speed, etc) and it seems that the new update doesn't like it. If I delete the python line, the retropie command line and the RetroPie UI work as expected. Not sure what the conflict is, but it's clearly to do with the script on my end.

Below is the autostart.sh if you're curios. Thanks so much for your help!

@zrs6v4 Try testing the hotkey combo with jstest and see if the buttons register ok when pressed at the same time.

Please add some info about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

What emulator are you using for arcade emulation ? We have several mame versions included - are you using mame2003/mame2003-plus/mame2010 ?

Just for someone else experiencing the same problem, make sure you have free space left on your sd card. Check if the expand fs ran successfully at some point.

@studysession double check your GPIO connection. Also try switching to unsafe shutdown (switch in the case PCB) if you have that and see if you have it to power on.

This is a common problem for arcade emulation, so you maybe want to read and understand how that works first, from https://retropie.org.uk/docs/Arcade/.
If the ROM doesn't work, then you'll need to find the correct ROMset version for your emulator and get the ROM from that collection version.

If the issue appears only for arcade ROMs, then most likely your retroarch.cfg for that system is incorrect. Find the file \\retropie\configs\arcade\retroarch.cfg and replace its contents with

# Settings made here will only override settings in the global retroarch.cfg if placed above the #include line input_remapping_directory = "/opt/retropie/configs/arcade/" #include "/opt/retropie/configs/all/retroarch.cfg"

Try again to boot an arcade ROM and see if it works.

Thanks for the responses to my question!!

I've already tried to downclock the device, that didn't help a lot though, yes I have overvoltage set to 6, however I tried to disable it for testing purposes, sadly it didn't help.
I actually only used gles2rice since my games then run at 1080p, all of the other options run at a realy low res, and when I look into the menu where you can change the video output, it's set to 1080p.

So I think my new question would be then how to set the "real" resolution for one of the better emulators to 1080p.

@Clyde That would be awesome. I've written a script that will take a folder of videos and, using FFmpeg, overlay images on top of them like scan lines and a bezel and spit out a new video. It would be so nice to be able to do this as an image instead like retroarch does.

@challenger2010 A bit strange since the filesystem should be the same (ext4) in RetroPie 4.5 and 4.6 resp. Debian Stretch and Buster. But good to hear that your problem is gone. And thanks for sharing your solution.

Can you post the info requested here? It will help to troubleshoot your issue. https://retropie.org.uk/forum/topic/3/read-this-first

Also may want to take a look at this post. Specifically the pi 4 section.

@mitu said in Creating Save States with a Single Button Press:

pressing only Start should exit the game.

My experience with (retropie 4.6) is that (luckily) it doesn't. Which at least for my purposes is good. Should this change at some future version, then if 'input_enable_hotkey =" and single press hotkeys are what's desired, then one would need to change that mapping in RetroArch configurations somewhere to avoid exiting emulator when Start is pressed. (it's almost like the old joke on Windows - you press start to to stop/exit ;-) ).

If you're still using mame4all, then I don't think there's a solution - it's a known problem and since there's no new development is happening for this emulator, it's unlikely it got fixed. I think there was a recent topic with the same symptoms for the latest RetroPie version.

Otherwise, please open a new topic instead of bumping a 3 years old topic, and add some info about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

@IanDaemon I never played it myself but I stumbled on it one time and looks interesting

@mitu Actually, it's a lot quicker with omxplayer disabled. Are there any actual benefits to having it enabled?

UPDATE: Seems that a lot of clips only play audio
