so , the only benefit to run retropie on 64bit system (on raspberry) is use dolphin-emu

Check out this thread if you really want to push for Gamecube on the Pi.
https://retropie.org.uk/forum/topic/28459/latest-gamecube-developments-on-pi4

From reading that, some games work ok, but many others are not likely to run well enough to enjoy playing them. Running Dolphin is a pretty big job for a Pi 4.

EDIT: As development continues on the various drivers and even Raspberry Pi OS 64-bit, this situation could improve. But keep in mind many of these things are outside of the control of the RetroPie project.

@jeromespana Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first

We don't support 3rd party images. Install the image from this site and we can help with any issues you have.

You need to be playing a 4way game for the option to show in the menu or else it will be hidden. Run a game like pacman then the option will appear.

@common763 when you power off the Pi... Are you just killing the power, or using a safe shut-down script.

Or even a Mausberry?

@churchill7 in mame2003-plus and mame2003 this core option will be hidden unless you're playing a game that uses the feature. I recommend running pacman then going into the core options.

The default is probably decent though like you observed in Tron.

@mitu said in Emulation station going off the screen:

Please add some info about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.
Are you starting EmulationStation rotated also ?

Yes.

Actually, with Retopie 4.7.1 lr-mame2010 TAB menu, input general/this game is OK.

But... on one of my RPI4, Retropie 4.7.1, i don't see, in lr-mame2003 TAB menu, the inpur general/this game. I see only dip switch, analog controls etc.

What have I done? :-o

There is an option to disable/enable them from retroarch?

EDIT: Solved! retroarch>quick menu>options>Legacy remapping (!NETPLAY) on/off

@thorr69 Yep, they're all in there. :-/

@mcreek Please show a screenshot of the usb stick on your PC with the folder name.

@calvorejas

You are most welcome. :)

Can you please add more details about your setup and issue, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first ?
Use English please, this is an English speaking forum.

@mortalwombat said in Pi console ROMs: battery games (Zelda etc) won't save w/o .SAV files?:

...or if there were any limits to the amount of games you could save.

Under normal usage, the limits of saving would sort of look like this:

Battery save: 1 save file per rom (assuming it actually had a battery backup at all); the actual number of 'saved games' will vary based on the actual game. Super Mario World (SNES) for example, allows 3 saved games within the one battery backup on the cartridge. So 1 file would allow 3 game saves in this fashion.

Save States: I believe RetroArch allows you to use 10 save "slots" (0 to 9) to create save states. If you are careful and keep notes on which slots are for what, you could have up to 10 saved game states for various reasons.

Typically when I have played a very difficult game, I would use Slot 0 to save whenever I finished a level and had good health, weapons, etc. as if I performed well. I would switch and use Slot 1 to temporarily save my progress after difficult jumps, mini bosses, etc. and if I take too much damage or lose an important item I reload Slot 0. This makes games like Ninja Gaiden or Castlevania manageable if I don't want to spend 80 hours of my life memorizing and mastering and old game with limited or no continues.

@alphabetapie said in Question About my Backup Images:

instead of just imaging the used portion of RetroPie (which is only a few hundred megabytes)

how are you calculating this? a retropie installation should be several gigs.

it has to create an entire 64gig ISO on my desktop of all that empty space. Since I need multiple backups, this is going to take up a lot of room on my HDD for nothing.

https://github.com/Drewsif/PiShrink

Do I have to always image the entire SD card, even if unused, to ensure I get a 1:1 copy that will seamlessly be restored when I use a program like Etcher to burn the image to a new SD card later?

it depends what you're changing - you could backup the individual configuration files you've changed.

Also, if I were to give this image to others to burn to a fresh SD card, does the gig size have to match perfectly? Meaning, what if I have a 64gig image and they try to burn it to a 256gig SD card?

the image has to be less than or equal to the size of the new card. you can expand the file system to consume any extra space on the card (pishrunk-images will do this automatically)

@saccublenda said in [[Solved] Pixelated and juddery background layer in > > I can use the hotkeys to browse and control the retroarch RGUI, but I cannot press the start button to start this game.

Try changing the controller type from DualShock to standard.

Thx - I managed to fix this problem with the multitap emulation option - I made an edit/update below: https://retropie.org.uk/forum/post/248454

OK, so I was able to solve it; a couple of steps I think were necessary, the others I did as precautions.

Basically, the main issue was that my runcommand-onstart.sh and runcommand-onend.sh files were empty; these need lines to trigger xboxdrvstart.sh, which in turn should allow the GPI controls to be recognised by Mame4All. Here's what I did:

In /opt/retropie/configs/all/runcommand-onstart.sh I added the following:

#!/bin/sh

source /opt/retropie/configs/all/xboxdrvstart.sh > /dev/null 2>&1
sudo pkill -STOP mpg123 > /dev/null 2>&1
fbset -g 320 240 640 480 16

In /opt/retropie/configs/all/runcommand-onend.sh I added the following:

#!/bin/sh

source /opt/retropie/configs/all/xboxdrvend.sh > /dev/null 2>&1
sudo pkill -CONT mpg123 > /dev/null 2>&1
fbset -g 320 240 320 240 8
fbset -g 320 240 320 240 32

(the lines about mpg123 are, I think, related to background music or something like that; probably not needed, but I borrowed these from a pre-made GPI image so thought safer just to copy everything.)

Then, after a restart/reboot, I switched the GPi's D-Pad to axis mode by by pressing START+DPAD LEFT for 5 seconds, until the purple light flashed.

I deleted default.cfg in /opt/retropie/configs/mame-mame4all/cfg

Finally, I the went to GPI's 'Controls Updater Menu' and ran that script, just in case.

@alphabetapie said in I Need to Go BIG For My Next Build:

[FAILED] failed to start usbmount@dev-sda.service

The error is benign and can be ignored. /dev/sda is the whole disc device, so it cannot be processed (since it has not filesystem). The partition you created is on /dev/sda1 (1st partition on disc) and it works fine, as you already noticed.

Thanks a lot for confirming! Much appreciated.

@sgrontflix I think that the latest updates to the emulator conflict with old configs. I ran into the same problem, no matter the setting, the controller configs were wonky across all games. I had to remove all the custom settings and redownload the emulator to get default configs for it to be consistent again. I think that it has to do with moving the controller type from settings to controllers and the added mutitap menu. 🤷‍♂️

@brandflake11
I tried doing my initial plan of mounting the drive in fstab, but it didn't work either. I think What I'm going to have to do is like you suggested, using softlinks but pointing to a /external/ folder inside the rom/system folder. I did some testing last night, where I had symlinked the folder and had a few roms inside. I also have a gamelist.xml file and a /media folder where all the videos for ALL the games exist. Using the subfolder, I can see all the roms that are "internal" and a separate entry called external, when clicked on opens up all the games that are on the external drive. When I un-mount the drive and reopen ES, the "internal" roms are still there but the "external" entry is gone. This works by configuring ES to have the setting Always Parse Gamelist to NO, that causes it to scan for the files at launch. If set to YES, it will list all the games whether they exist or not. The nice thing is that ES will scan the roms and find some games with the drive disconnected and will still load the appropriate media (I think it loads them from the gamelist.xml in this case, where it sorta soft-loads the xml but isn't restricted to it). The only problem I have now is that the games loaded in the external folder (when it exists) it doesn't load the media. I think this is because it's still going to try to load the gamelist.xml and the paths no longer match. I'll just need to rescrape. That's what I'm going to try to do tonight.

So yeah, using a symlink like this works:

ln -s /media/retropie/Passport/roms/amigacd32 /home/pi/RETROPIE/roms/amigacd32/external

You just have to live with having the external games be listed in a EXTERNAL folder in your browsing lists. When I tried to do it on the file-level, it still tried to load and display all the linked files in the gamelist.

@barbudreadmon Thanks! I had put the cheats in the wrong folder.
