Should be possible, why not ?
Use the GPIO inputs for simulating keyboard keys input and map them to the emulator's controls. For this bit you may need some additional configuration or scripts to interpret the GPIO pins state, but other than that there's just configuring the emulators' input for the actions you need.

@sleve_mcdichael Thanks! That was exactly the issue I was facing!

Some time has passed from this post and just wondering if anyone has a fully working version of House of the Dead for the Saturn with working sound? This isn't a rom request, just looking for advice/experience if anyone was successful.

Solved

I just tried to boot with just the lid of the NESPi case removed, where the SATA-to-USB adapter is located, which was of course plugged into one of the Pi's USB 3.0 ports.

Now it boots without problems!

Since these problems started after I performed an update of RetroPie, I suspect an EEPROM update of the Pi made the SATA-to-USB adapter incompatible. I never would have suspected the case lid as it has worked without problems in the past.

At least we finally found the problem. I'll now try to fix this by updating the firmware of the adapter in the case lid and report back whether it worked.

Thanks for your help, mitu! :-)

@daubsi said in Retroarch Menu is not shown anymore:

@windg Ok, understood! So you’re saying that retroarch itself sometimes corrupts the config when using its own function to save?

It is not corrupted, but changed from the default settings that selected for the proper RetroPie operation and it happens everytime you save the settings from RA menu.

@Mayonaise said in audio bugged out:

is there any alsa applet for panel?

Yes, I think it's the lxplug-volume package.

audio config always says enable pulseaudio

Are you using the latest RetroPie-Setup version ? Did you run an update after installing from the RetroPie image ?

@sleve_mcdichael cheers and thanks again for reporting back. :-) One more thing: As a courtesy for other other forum users (and robots from some search engines): Could you please edit the title of your first post and add [solved] somewhere? Thanks.

@Red732 said in Onscreen Gear Shifter Visibility Options:

Does anyone know how to remove the onscreen gear selection from games like Pole Position? I’ve seen it before, but I can’t remember where the config is.

Weird that I was just playing with this on Monday...

Complimenting what @dankcushions provided, and using Pole Position with any version of MAME other than 2003-plus:

Hit TAB on a keyboard to toggle the MAME menu Select Video Options

Then, depending on which version of MAME you're using:

For lr-mame2003

Select Dip Switches Set "Display Shift" from On to Off

For lr-mame2010 - lr-mame2016:

Select either "Standard (4:3) or Pixel Aspect (8:7)

For lr-mame 0.222 and below:

Select one of the "Screen 0" options instead of the default "Shifter-R" option.

For lr-mame newer than 0.222:

Select "Screen #0" Then select one of the "Screen 0" options instead of the default "Shifter-R" option.

For the bleeding edge versions of lr-mame, there are some newer video options that allow the shifter to be off the screen as another option.

i use my Pi-Models 1-3 with CRTs (1x Samsung / 1x Bang&Olufsen)
Of course i wanted to connect the Pi4 also with my CRTs, but i only tried it once and burried that idea.
At least concerning the composite out.
Maybe i had bad luck and my Pi4/the AV-socket is broken, but the picture was H-O-R-R-I-B-L-E!!!

I am still searching for a verfied method to connect with better quality (Gert666, Pi2Scart etc.), but did not find anything that runs out of the box without any issues or performance loss :[

@djavs said in IM STUCK start4.elf:

i got this image Raspberry Pi4 running VIRTUALMAN PLAYBOX v1.4.5.14 512GB RETRO-BLISS-REVOLUTION!

We don't support 3rd party images, as outlined in https://retropie.org.uk/forum/topic/3/read-this-first.
Use the image from https://retropie.org.uk/download and you'll not have this issue.

Well it was worth a shot. Maybe I’ll keep playing around and stumble across something. I appreciate the help though.

@TeeEl Sorry to hear that. My arcade cabinet has a 32" tv, but the problem started for me a few months back. But I couldn't pinpoint exactly what caused the change (I already had a similar post about it). Thankfully for this post, I was able to find an option that worked for me. I hope you do too!

@windg Thanks going to buy a new SD card today.

Re: Fixing a Konami arcade cabinet.

So turns out this model is super old. It has a monitor and a VGA port (the model is: hp Hewlett Packard Pavilion) the motherboard seems to be okay. Just dusty. I plug in everything and the monitor works but nothing shows on the screen. I'm starting to think it is the power supply of the pie or the VGA port not working. Any ideas?????
