Hello, I am trying to build kind of a custom loader that the user can choose three games from instead of having the whole emulationstation menu to contend with, this is something that I am building in the godot game engine to port over to linix with the godot emulator and run on the pi. I am running into a little road block with changing games on the fly, as the emulator for godot will be running a "game" and when the user selects a game it will switch over to that one. I have my single-game boot working fine via run command, and I tried using this script https://pastebin.com/jmNJxMcJ to kill the game, but it seems it just looks for a running emulator, which it does not find.

Any simple commands on how to switch over from one game too another on the fly like this?
Much appreciated.

Commodore 64 on Retropie:
Some games the joystick works (Pac-Man), but for other games the Joystick does not work - no response (Moon Patrol, Mr. Do....)

I can't figure out why.

Emulator: VICE
My settings:

I have build a retropie inside of an NES cart using a 16gb image from 2017 onto a pi zero. I would like to add some C64 games and DOS games to it. When I tried, it told me that I need to upgrade from Raspian stretch to buster. So I set to learn the steps to do that. However, I get as far as updating the apt packages in the /ect/apt/sources and my pi tells me that the ect/apt and even the /ect file is missing.

I'm still very new to using linux in general, and my research into this problem isn't helping me. I would like to know how I can create an /ect/ file and i suppose also an/apt file where I can place the deb packages addresses for debian Buster. or do the thing where I replace the Stretch in those files to Buster. But first, I need to put my /ect/ file back in there. How?

Under roms I have a scripts folder.
In the script folder I have
AttractMode.sh

#!/bin/bash
pkill emulationstatio
attract

It works. But just wondering if there is a better way to exit ES and launch attract mode from within it?
Basically I want a script command to jump back and forth.

Hi All,

Raspberry Pi 4 build. Imaged from the website.

For some reason, anytime I try to open an NES rom, it just goes back to the selection screen. I have tried selecting the different NES emulators, and unzipping the files (all are .nes).

Any thoughts on to how to get it running?

I am using a Picade and for some reason, videos only play audio when using OMX acceleration, however, the volume on these videos is incredibly low. If I turn the ES volume up to 100% it's still a fairly low volume, but the games are incredibly loud. I spent four hours searching around and couldn't find a complete answer on how to adjust the OMX volume for if it's even possible.

Hi, i am setting retroarch in the video-options just to try the pixel-perfect setting.
Then the screen changes, i want it normal again, so i set the setting to the same it was before,
you know what happens, the screen does not change back to as it was before changing any setting.
Have to exit the game and try again.

Why do i find everywhere these kind of amateur bugs in this software ?, dont you guys test anything ?
Why do i find all those bugs ?, because i am a programmer myself, or no one else notices them ?

thanks for reading

Hi, i installed the retro-pie image on a micro-SD card with a program called 'rufus'.
There was no option, it could only be formatted in blocksize of 8192.

That is weird since 4096 is the default blocksize, many times not even checked by a device.

What do you think about this ?
Can it cause problems ?
Do i need another program then rufus ?
Is 4096 not default ?

Strange.
How did you install retro-pie on what blocksize ?
bye

Controller used: 8bitdo SN30 Pro+
Error messages received: None
Emulator: All
Attachment of config files: retroarch.cfg https://pastebin.com/uDMVcZUt

How to replicate the problem: Start recording or streaming from any emulator/quick menu.

I've input my twitch streaming key into the retroarch settings from the retropie menu, and set the quality to low for both recording and video. All emulators are unplayable (sloooooowwwww), but when viewing recorded videos, or twitch stream (it's a bit stop-and-start) it is completely normal.

Hi,

I couldn't find any information about mapping two inputs onto one controller button.

I am playing a Mame Rom Spiderman game on the Mame 2003-plus emulator.

The game uses two buttons (a and b) to jump and punch. If you press both, you can do a special move.

Can I map button "a" and button "b" onto a third button on my controller somehow (just for this Rom) so I can just press one button to do the special move?

I tried going into the retroarch menu when the game was running but that only allowed me to map one input to each button.

The controllers are 8bitdo sn30 +

Any help would be appreciated.

Thanks!

I noticed that the EmulationStation license does allow sublicensing. I was wondering if this option has been considered by the RetroPie maintainers and what was the outcome?

From my point of view it would be more consistent (and would also close a loophole e.g. for charging for RetroPie's ES) to put the RetroPie's fork of EmulationStation under GPLv3 same as the RetroPie-Setup scripts are.

Is GPL'ing ES on the roadmap of RetroPie? If yes: By when can it be considered? If no: What are the impediments of doing so?

Hi,
I use pi imager to format to fat32 and install retropie (latest from the imager) into 480 ssd (this spec https://www.ebay.com/itm/265245183201?hash=item3dc1d84ce1:g:RqsAAOSwQCxhAUV7)

when putting it on pi4 usb (blue connection) it works, but I'm not sure the filesystem expanded in first boot. (i install twice and the result is the same).

when I run

I don't get the full 480GB.

I also tried to expand filesystem using raspi-config. and acts as if it did the expantion and says that in next reboot it will show the full FS, but when rebooting, i still get a low disk size.

any idea why?

As the title says: I read a million of times that the Pi Zero can run Mega Drive and even many SNES games, but in my experience not even NES games run at full speed: I made some tests and I get 41/42fps in Alien Syndrome (and around 53 in sidescrollers like Castlevania).

By disabling shaders I get a boost of 3fps (44/45 instead of 41/42).

Initially I set the rendering resolution to 320x240 and the output res 1280x720, I didn't know that shaders look awful in 240p though, so I raised the internal res to 640x480 and the output one to 1080p.

However, I didn't notice any significative difference in performances, the games always run at 40/50fps (and with crackling music) at any resolution that I tried (which are the 4 that I mentioned above).

P.S. when I'm inside retroarch's menu the game runs at full 60 and sometimes it keeps the 60 when I exit from the menu, but after 20/30 seconds the framerate starts to drop and ultimately stabilizes at 41/42

P.P.S. I also get phantom inputs on the Emulation Station menu, but not in games, so I didn't try too much to solve the problem (also because from what I read it seems very hard, if not impossible, to get rid of it).

I updated it from source today but it still runs almost nothing, whatever settings I try - it just boots to the Memo Pad.

(The non-lr atari800 runs, but in a teeny tiny window.)

Is it totally b0rked, or is there just something I need to fix in my configs?

Is there a way to change the background image for Retropie? Is there any specifications of what it must meet in order to use a different one? IE resolution, max file size, png/jpeg etc. I have a Raspberry Pi 4 B (4gb ram) version

I was wondering since I have not seen it mentioned on the site. I would like to know if RetroPie is Open-Source.
