I think some of the emulators support per rom configurations but not sure about all of them.

@mediamogul I think I found out the source of the bug, it seems to be the steamcontroller driver. For whatever reason there was no log of it yesterday, but the syslog is filled to the brim with error message from its py script. Plus the timing fit perfectly, one message every 2 secs.
Gotta afk for a couple of minutes, but will report back on it soon enough.
I'm just gonna leave snipet of the log there: http://pastebin.com/qk9uW2dh

Gonna uninstall the steamcontroller driver for now and report the bug to github

EDIT : confirmed steam controller driver is faulty. Back to smooth footage and xbox controller for now I guess. Thanks for not leaving me alone on this one guys ^^.

@paffley Glad to hear you got everything working.

Regards metadata, have you tried Steven Selph's Scraper?

You could try using the scraper on your PC . Download the relevant version here and place the binary in a folder containing your roms. They can be from any system but not a mixture of MAME and consoles as they use different databases.

Running the scraper will create a gamelist.xml file and a folder containing boxart which you can place in your roms folder on your pi. If you want to keep your scraped data in configs/all/emulationstation, then you have to use the -image_path flag (or use the find and replace facility in a text editor).

@dankcushions okay that makes sense than.

Moving to the usual option of just using the second player controller to play, I read that people sometimes having problems when using two different types of controllers. I could just configure a USB Keyboard as controller player one and then configure my iBuffalo controller as player two to play correct?

Having the same issue, but I can't find any USB daemon tools under retropie setup and tools.

@Kilika

You need to find a PSX bios file and put it in your BIOS directory. Try looking for SCPH1001.BIN or
scph5501.bin those are both very common.

@Spag said in Too many ROMS & Systems showing up:

looks like its just the gameslist which is showing up for some reason.

Sounds like attract mode

@markyh444 haha whoops. Leave it to me to miss the big red ban flag next to the name lol

@edmaul69 Yes, tried the game mode. Thanks!

@Hockmiester why dont you just open the file /opt/retropie/configs/megadrive/retroarch.cfg and manually add them? But you need to undo whatever configs you created.

I'm trying to do this also, but its currently not working... What sort of Retropie version are you on @franck ? Does it work with the latest?

Thanks for the tip, going to do that, have been working on my goal, wow did I just learn a lot. Took me a bit to figure out why when I commented out the most obvious parts, "Players:" moved to a slightly different spot rather than going away like everything else did. I'm on a test setup and have re-imaged several times, so I see what you mean about moving the file. Am I correct in assuming that I,m not really getting rid of the data, but moving it off the screen? Thanks!

@Darksavior Thanks for the reply, that is my next option, but it is one of those problems that bugs me and I want to figure it out!! :) lol.

@MWGemini
Thanks for the help. I'll try with a USB wired gamepad when I get back home later this week and see if it works.

@wilburburns

IE: I want the Alexa audio output to go to a Bluetooth audio device, or a directly connected 1/4" jack speaker, and all of the Kodi/RetroPie output to be pushed out through the HDMI port.

Kodi uses it's own audio settings so if you want to use the 3.5mm audio jack with Kodi, you have to go into Kodi's Audio menu and change it to your 3.5mm audio jack (or both HDMI and 3.5mm).

Hey guys, update, I think the issue was a bad rip.

I came across a different ISO and it works correctly now.

I will be keeping this in mind for the future.

Thanks all!
