With regards to the controllers, definitely. Check the documentation: https://retropie.org.uk/docs/GPIO-Modules/#gamecon_gpio_rpi

Power buttons are a bit more difficult, as the Pi needs to be shutdown cleanly, you can't just rip the power away and expect it to be fine next time (sometimes it is, but not always). You could create a custom shutdown script or use something like the PowerBlock or actually, to combine the function you could use the ControlBlock https://blog.petrockblock.com/controlblock/

@johnny5126 said in How to know what button is what:

where i can figure out what button is assigned to X, Y, etc? I have my buttons connected to an Ipac2

You know what you wired up to the ipac2 terminals so therefore you know what function each button has according to the instructions for the ipac.

@killias2 Looks like a failing SD card or corrupted filesystem. Without a Linux installation to access the SD card and try a filesystem repair, re-install might be the only option.

Switching to AdvanceMAME resolved this issue.

All solved and work as expected after modifying mupen64plus.cfg from:
# Controller configuration mode: 0=Fully Manual, 1=Auto with named SDL Device, 2=Fully automatic
mode = 2

to:
# Controller configuration mode: 0=Fully Manual, 1=Auto with named SDL Device, 2=Fully automatic
mode = 1

I have done my own mapping, at the end:

@dojobaggins OK, so you might have had an older release where there was no 'Hotkey' button present in the input configuration dialog and Start + Select was automatically set. This is what you can do

configure you controller again in Emulationstation when you get the Hotkey selection, just long press the A button to skip it, then save the configuration (press A). there will be a prompt asking you if you want to use the Select button as a Hotkey, since you didn't assign a button to it. Choose yes here.
Now the Hotkey will be mapped to Select and you'll be able to use the same exit shortcut as before.

You probably have a Raspberry Pi B+ rather than a Raspberry P 3B +, so you need to use the Pi 0/1 image rather than the P 2/3 image.

@bibbleboberoe What you're seeing on your PC is the boot partition, which is a small part of the SD card containing only a few files. You PC cannot see the Linux partition where ROMs/BIOs/other files are stored. See the Transferring Roms section of the docs. You could read the SD card's Linux partition if you have a Linux PC though, but not from Windows/macOS.
As for the 2nd problem, is your RetroPie system connected to the network - the same network where your PC is connected ?

@dash-dot I bought the adapter because for the life of me, I couldn't get my controllers paired with the bluetooth on my pi. I tried everything. Some people have had luck pairing them, but unfortunately I was one person who couldn't get the generic ones to connect. I leave my pi in one place all the time, so I don't mind having the adapter at all as long as my controllers work ! :-)

EDIT: I didn't have to calibrate anything. Plugged the adapter in and synced my first controller and the other ones followed suit just by turning the controllers themselves on. No other messing around with them ! I bought this adapter as I was new to the scene at that time and didn't know what other dongles existed for the controllers to function.

@douga There's a very famous solution that's been around for a long time called Keyrah, you can check it out here http://www.vesalia.de/e_keyrahv2.htm . I know the C64 runs quite well on VICE but because it's such a famous machine there are better solutions around in FPGA if your life depends on a good modern version of the C64 in your original case. No real need to software emulate this one.

Hello! Did you ever gets this figured out? I am having the same issue! For player two it’s even worse!

@squiike

Nothing will be deleted.

please ignore/delete this thread (sorry) it seems I've worked it all out using SGM-V2.01.sf2 and i'm cool with that. Apologies for wasting anyones time.

@mr-emu Thank you for sharing your solution.

I got the Ultimarc BlueHID working after a fresh reinstall of the latest RetroPie 4.4. Which is great news, I can highly recommend this controller board with RetroPie!

How do you install blobby volley?
I tried to search "blobby" in install package,
but I can't find it.

Can you help me?

Thanks.

@renario910 said in Retropie on ubuntu is broken.:

so how do i edit sources.list?

from a terminal, type sudo nano /etc/apt/sources.list

but i think it's also important to familiarize yourself with some basic unix/linux concepts, since this is turning into more of an Ubuntu support thread.

Think I may have been a bit dim - I was originally adding extra inputs and it didn't do anything, I've since overwrote all of them and it is reading the input now. Thanks for your help folks.
