I have finally completed the how-to guide on compiling and installing the FFmpeg suite, which allows for recording from libretro-core RetroPie emulators.

I'm starting work on part 2, which details how to enable the recording features within RetroArch, and how to modify the various Emulation Station scripts to add the option launch a given emulator with the recording option enabled, as well as how create configuration files to change how ffmpeg is used.

@floob : Thanks ! I did this (a separate config per game for vertical games). It does the job as I have a moderate number of games :)

For anyone who has the same issue:

I have resolved this issue for myself. I followed the manual install process ( at https://github.com/recalbox/mk_arcade_joystick_rpi ) but instead of step 2 (install linux headers), run:

sudo apt-get install raspberrypi-kernel-headers

This will install a headers package, however because I had been messing around I had to remove the old header files first, if you get a message about "file already in another package linux-headers-4.xxx.xxx" then run

sudo apt-get remove linux-headers-4.xx.xx

then rerun

sudo apt-get install raspberrypi-kernel-headers

once this has completed successfully, carry on with step 3a.

@matalog

What i am looking to do is have my wii u pro controller use different x,y,a,b button number assignments from my ps3 pads - because they are numbered differently on the devices - both on the NES.

Did you read through the First Installation instructions ? It's listed there - https://github.com/RetroPie/RetroPie-Setup/wiki/First-Installation (start+select) - but some non libretro emulators may differ - details are all on the wiki

See post:

I have more questions.

Thank you that answers my question clearly.Very much appreciated

@NySoCalFool Disk images should be in /home/pi/RetroPie/roms/c64...

Hi, yes i know i can access it via samba but transfer of the files via that are really slow on my network, hence wanting to do directly.
Backing up as an image is of no use since I wouldn't be able to restore it without wiping all of the new image that I have to write to the disc with the new build on it.

I'm using FUSE-ext2 for Mac and have now mounted the drive and am now copying across.

thanks anyway.

It was a zip dependency not in the install script. Install zip manually with

sudo apt-get install zip

@Wolfman100 said in RetroArch Config Confusion and Issues:

ha..also a 'hear hear' for that!as I mentioned though,shouldn't I be able to simply delete the config files for PSX I changed and it'll revert to default 'global ' settings?

I noticed when I (re)install a core using retropie_setup, it creates a retroarch.cfg.rp-dist in the respective config directory. You can use it to "restore factory settings".
;-)

Handy-Dandy Indeed!

@opensourcefan
I managed to get the audio out by the 3.5mm jack so that not sound in retropie menu or even in the game . but if I do the terminal " aplay Front_Center.wav " it will give sound. If you see this alt text . You can see that the sound is 0% . always put 100 % but when I see this again at 0%. I know this not the record definition . It will be that I can help. I am using a 5inch LCD to be able to make a "game station to take wherever I see it . so the sound and me to give this a lot of work . help me

@Lamaman1971 said in Arcade Build Front End Advice:

Hi everyone,

Im building my second arcade machine - upgrading from a single player with trackball to a 4 player with trackball, light gun, push/pull spinner etc. A big job but achievable with my Pi3 and a little help from Ultimarc! Anyway, much of interest lies with classic arcade games and as such - due to the controls I use - I use advancemame as opposed to the other mame emulators.

I also use RGBCommander for the LED buttons and another reason to use AdvanceMame is that it uses a unique process ID - meaning I can change the colours of my butttons between Libretro Emulators and Mame, which is cool.

Now it appears we have a choice in terms of front end but, from what Ive read, Emulation Station is still the best bet for me as support for AdvanceMame is poor in AttractMode - does anyone have experience of using Advancemame and attractmode? Does it work? Or does anyone know of other versions of Mame in Retropie that have equally good support of HiD devices?

Cheers

Mark

Not true I only run AdvanceMAME and Daphne on my Rpi3 with AM and it runs perfectly, maybe a little quicker than ES to load games and return to the display.
Another Nice thing about AM is you can run a combined list and only have one dispaly rather than multiples for different emulators.

what said

said that some programs had their own settings but this will change them all to 32mb and only offered me to go ahead

?

Nothing has changed in RetroPie regarding gpu mem, but raspi-config / firmware has changed which may have had some effect. Need more information to advise. Note that the RetroPie image is just RetroPie installed on top of a Raspbian Lite image - we are not responsible for the underlying os/firmware/kernel etc..

@jkristof The question is really two questions:

What trackballs are supported by the IPAC2?
This isn't really a question for RetroPie, but rather, a question for Ultimarc.

What trackball support is there on the Raspberry Pi 3?

As far as Pi support goes, a trackball should work like a mouse interface to the Raspberry Pi--any model. The best answer would have to come from someone who is using an IPAC2 on a Pi. I use the Ultimarc U-Trak, which I expect behaves similarly. I can tell you that it does indeed work like a mouse. If I run X I can move the cursor--it's a mouse.

It's one thing to have your trackball move a cursor on the desktop in X. It's something else to tap into that device with an emulator. Not all emulators do it. AdvanceMAME works very well with mouse interface devices (trackballs and spinners) if properly configured.
This Post describes the settings you need. It's probably your best MAME option.

I also have the trackball working fine in QUAKE 3 without any configuration needed, and I expect other ports that support the mouse would also work.

Make sure you're actually exiting properly.

https://github.com/RetroPie/RetroPie-Setup/wiki/FAQ#why-arent-my-in-game-saves-working-properly

If you are actually exiting properly, make sure a save file actually got generated in your rom directory. If it exists, you could try an alternate emulator. I've had some hit and miss results with the way gba handles save data, but usually that only causes problems on the first boot. Messages like save data corrupted and such.

@Lamaman1971 said in [exit mame when using a j-pac](/topic/1729/exit-mame-when-using-a-j-

If you want to loose that annoying quit dialogue that pops up take a look in the advmame-1.4.rc file for Misc_Safequit and set this to a resounding No.

Oh! Thanks for the tip, that dialogue message has always been a pain. I had no idea you could remove it.

Since this post i have realised i can no longer go into retropie-setup either, screen fades to almost black then freezes.

@jkristof I have purchased the ipac2. It has caused me some problems. I will detail them here for you. There are many resources on the web that discuss it but my problems seem to be with retroarch configurations. Have a good read of this thread first. Now I have experimented with Joypads, PS controllers and keyboards and they all work perfectly so when I built the cabinet and invested in an ipac2, I expected the same. For non retroarch based emulations like MAME4ALL and AdvMAME, it worked instantly and perfectly as it is already configured for MAME so in answer to your question, if you wire it correctly, it will play MAME games easily. However, I wanted to run libretro emulations so that certain games can run using FBA and NEOGEO roms. I made a mistake in following the autodetect sequence of retropie for the ipac which appears to be detected as a joypad. If you follow this then try to edit your configs, there will be problems in getting player 2 to work. I could not solve it for days and was about to give up. I was confused that the ipac was giving perfect key strokes like a keyboard but retroarch was not having it. The answer for me was to configure a normal keyboard first that was detected as a keyboard. Configure everything using it then disconnect it. If you then edit retroarch accordingly and reboot, ES will not ask to configure your controls and both sticks and buttons will follow the mappings in retroarch.cfg. If you don't configure a keyboard first, there will be issues if you follow auto detect. Even though the ipac detects key presses from a keyboard, it is not detected as one. According to the other threads on this forum, the firmware that is supplied makes the ipac appear as a joypad but there are other firmwares available here. Hope this helps you.
