@Darksavior nes accuracy is measured through various tools to verify correct ppu/cpu/apu operation and proper support with the most popular nes mappers, support for obscure mappers isn't accounted during those tests tbh.
Mesen probably had missing/broken support for that mapper 078 used in 2 games (Holy Diver and Uchuusen - Cosmo Carrier) at the time of its release.
Afaik Mesen is the only emulator getting 100% at those tests, nestopia is around 80%, quicknes is around 70%, fceumm is only around 50% and the least accurate nes emulator available on retropie.
I don't know if there is any nes emulator with 100% mapper compatibility, there are several hundreds of them and they all need to be coded separately.

Can you post your config.txt boot configuration ? What version of RetroPie are you using ?

@Lolonois Edit: was able to get it work after all! Thanks!

You need to give us some more info to help diagnose your problem.
Did the image you're using has ever worked on a Pi4 ? When you say you 'updated so on old board' - does this mean you've used a Pi3 with the same image/sdcard to do the update ? What image are you using ?

@mitu

Ah, makes sense. Thanks for your help!

We’ve got most of it working now. Just need to add a few tweaks to the code to write the metadata to the screen and make the info displayed selectable by the user. Thanks!

@racecarmike said in Games not loading.:

I bought the SD card off of Amazon and I used it on my raspberry pi 4

Then ask the seller for support - we don't support 3rd party images in the forums, only the image from https://retropie.org.uk/download.

Have fun. 🙂👍️ unison-gtk should be available in most Debian-based Linux distributions. Don't know how it is for Mac or Win.

If your Pi has a keyboad, you can also press F4 in Emulation Station to get to its command shell, and then enter sudo nano /opt/retropie/configs/all/autostart.sh to edit the file. In the editor, press Ctrl+xfollowed yand Enter to leave and save the file (or press n to not save it). You can leave the command shell by entering exitor pressing Ctrl+d.

Finally, you can also use SSH (Secure Shell) to access your Pi. See the Docs about that.

The fuse package hasn't been updated in quite some time. Unless you had a very old version, any recent update wouldn't have changed anything in the emulator.

Are you using the standalone emulator or the libretro core (lr-fuse) ? Please add some info about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

@Ashpool thanks for the pointer :)

Got it working using that script.

If it helps anyone else my /opt/retropie/configs/all/autostart.sh file looks like:

sudo /home/pi/RetroPie/scripts/multi_switch.sh --mausberry & emulationstation #auto

(All on one line in the file)

I suspect my missing piece with the 'stock' mausberry install script was adding it to the autostart file, but this alternative script works so will stick with it. 👍

There is a new version of ppsspp (v1.13.2), RetroPie is using the v1.12.3. I haven't test this, maybe it have better performance. If you want to test it, you have to modify the ppsspp.sh file and build it from source(it takes 2+hours).

@Floob @dankcushions Thank you. I just had som eoveride of menu_driver in the retroarch.cfg from some systems folder so i still had rgui for some emulations. but know i have matched everything against the parent retroarch.cfg menu_driver and it works.

@smartgenes Solved. I thought I was up to date but just updating the packages solved both issues.

One issue though is full screen, how can I switch from windowed mode?

@BuZz Thanks so much for your help in fixing this.

Also, thanks to everyone else who tried to troubleshoot the issue. I realize I'm not active on here much lately, but the way this problem was handled is an amazing reminder of how this a really excellent community.

@mitu Thank you. After some more research I finally was able to resolve the issue. It worked with Mame2010 but controller needed to be configured from Retroarch's light gun option(Select+A) inside game and Dolphin bar needed to be set to Mouse option. Everything working fine now! :D

Some ps1 games are a crashfest on pcsx_rearmed but mostly fixed when using duckstation or swanstation.

@bbilford83 said in Yabasanshiro exit game:

@shavecat OK great. That I think I can help with. Go to \retropie\configs\all\emulationstation\ and you will see an es_input.cfg file as well as an es_temporary.cfg file. If you open up the former, you'll see a list of all the controllers your setup currently will recognize and their mapping. Each one will be introduced with a line that looks something like this: " <inputConfig type="joystick" deviceName="8BitDo SN30 Pro+" deviceGUID="05000000c82d00000261000000010000">." Now open the temporary one, and you will see it will only list one controller. Replace whatever is in there now with the correct controller info from es_input.cfg, then save.

At least for me, that fixes the emulator mapping in yabasanshiro so I can exit again, but I've had to do it again anytime I connect a different controller to my pi.

Thanks, I'll give it a try.

@mth75 Thanks a bunch, I will look into it!
