Hi there,

Not tried RetroPie with the JustBoom boards yet, although our man Francesco (@GarageTechTweet on Twitter) is working on software tutorials as we speak so I've asked him to add this to the list!

In the meantime though, you should be able to add the following line to the file /boot/config.txt and it should enable the audio card:

dtoverlay=justboom-dac

You may also need to comment out the line following line by adding a # in front of it:

dtparam=audio=on

Let me know if that works?

Thanks

@hansolo77 said in Help Remapping non-LibRetro games/systems:

It sounds like xboxdrv is your favorite.

It is, but I do recognize that it's not a simple thing to jump into. After a cursory look at the different options when I was starting out, xboxdrv seemed to be the most versatile solution. The others seem to lack a valuable feature to me here or there, but they also seem a bit easier to setup and that can of course be a valuable trade-off to many people. I've even noticed a few features from other mappers that don't exist in xboxdrv.

Is it possible to use it just for 1 or 2 systems, or is it a complete replacement to the default xpad driver?

It can indeed be used with one or two systems. When used in conjunction with the xpad driver, the following line would need to be added.

--detach-kernel-driver

As I have never tried this myself, I'll leave the explaination to the xboxdrv manpage entry:

"Detaches the kernel driver that is currently associated with the given device. This is useful when you have the xpad module loaded and want to use xboxdrv without unloading it."

Can you give me some pointers/tips?

Again, I'll be honest. All this is not exactly easy. You may even find out that it's still not the right approach for your particular setup. However, if you find that it does work for you, it becomes pretty easy to configure these mappings over time.

When I started looking into this, there wasn't even an available guide, so I had to pour through the manpage and seek out help on other forums that made similar use of the software. As far as following the guide here on the wiki is concerned. I would recommend reading closely, asking questions and eat it one bite at a time. Any problems that will prevent it from working on your setup will present themselves in the first few steps, so you won't really waste any time.

Nevermind.

Is there any you'd recommend? Modmypi.com where I usually buy my Pi stuff only seems to have up to 2.5A.

@Raverrevolution

Did you find a solution for your problem?
I got nearly the same issue: My retropie is built into a controller-case which can be "docked" to a monitor-cabinet with usb audio.
But if I take the controller (including the pi) out of the dock, I want it to play all the sounds over hdmi.

i think i found the solution after a long time of troubleshooting

I forced picodrive emulator and as extra i set the resolution at 640x480 DPK-2 or something instead of default.
no more glitches in the textures!

I'm wondering if there is a way to swap between each shader at runtime. In this way we could match them on the fly..

@BuZz
Worked like a charm!
Thank you

@BuZz Thanks for the tip. I'll post this over there to see if anything positive can come of it. At least replacing a single-board computer is MUCH cheaper than a PC.

Seems I had a problem with permissions, when following the github wiki I was using the mount command with SUDO, and ofcourse the owner/group was root so the user pi couldn't read the mounted dir, the fix was to include the UID and GID for PI in the options during the mount command

sudo mount -t cifs -o domain=workgroup,username=<USERNAME>,password=<PASSWORD>,nounix,noserverino,defaults,users,uid=<LINUX_USERID>,gid=<LINUX_GROUPID> //<HOSTNAME>/ROMSSHARE /home/pi/RetroPie/roms

both LINUX_USERID and LINUX_GROUPID were 1000 in my case.

Hope this helps someone from wasting as much time as I have on this problem.

Ignore that - I misunderstood (And the PS3 controller does work ok in Ubuntu 16.04 unlike I said above - I just had to configure it by holding the playstation button it seemed).

You mean it's fine in ES and games, just no good in the retropie-setup menu ?

It works - it's just it doesn't use the same mapping. Left analog moves, and select will choose an option. This will be resolved at some point in the future, but the menus were never originally designed for navigating via joypad - it was added later via joystick to keyboard mapping. Since it;s mostly configuration and you are on a PC, it's not a big deal to use a keyboard to configure if you don't like the ps3 mapping.

I figured out the sound problem but I still don't know how to boot to ES

@Rikochet see https://github.com/RetroPie/RetroPie-Setup/issues/1798

you can add the product id / vendor id manually (assuming they both have different product ids) to the controller config in /opt/retropie/configs/all/retroarch/autoconfig (so you have two copies of it each with the difference ids).

You will however also need to manually set the controls up. Right now when controls have the same name we don't do this automatically. TBH the manufacturers should bother to give them unique names etc, but the cheap stuff often has missing device/vendor info etc.

example

# Hex vid:pid is found using "dmesg -w" or "tail -f /var/log/syslog" and converted to Decimal using http://www.binaryhexconverter.com/hex-to-decimal-converter # Hex vid:pid = 2810:0009 -> Decimal vid:pid = 10256:9 input_vendor_id = 10256 input_product_id = 9

Note when posting please also read https://retropie.org.uk/forum/topic/3/read-this-first first and provide the information as requested so I know your set-up.

@jnbui79 Any update? I am having this identical issue on my Samsung set. RetroPie works perfectly on every other TV I try it on.....

Please let me know. Thanks!

@jpretpiuser14 you may have saved a "per system" retroarch config which overrides it (eg by settings save config on exit to on in an emulator ). There are a bunch of topics related to this and some info on the wiki (Sorry short on time to explain further).

@jworkin after scraping your names will show up proper even if the filenames are a little less readable. You never want to change the filenames with mame as that is how they are identified by the scraper among other things.
