I tried it when I first got my RPi and I tried again just last week but never got it to work.

I have been wondering if a powered USB hub might work? I haven't tested it yet but if the adapter isn't getting enough power than a powered USB hub should work. If it is because of another issue then it will not work.

So I'm better off using lr-mame2003 and roms from .78 romset?

thank you both for your responses. I did read those wiki articles, but obviously I don't understand exactly what they are saying. Seems like there is a LOT of information, but I'm having trouble deciphering it.

i've googled a bit more what exactly was the Problem...
so it is the Intel Dynamic Platform & Thermal Framework inside the Bios who made this Problem to me... it isn't a big Problem to disable it at all... even when it is not exactly a mobile Computer like mi Ockel Sirius B

@maximus76 the page on the wiki works. If it doesn't show up, you should keep trying. Make sure you have the latest non beta firmware. I have 3 8bitdo controllers all paired with those instructions.

@GtBFilms this is the reason i decided to not scrape anything. I scraped the nes and every single game that was the first in a series got named as the second so i had it listed them like this:

Lolo 2
Lolo2
Lolo 3

Super mario bros 2
Super mario bros 2
Super mario bros 3

Plus there were other games scraped as the wrong game.

Many thanks for your reply, they have helped me a lot.

Thanks for the information :)

Replying to myself, incase anyone else has the same problem and stumbles across this post - this was a scraping issue, for some reason the scraper is no longer retrieving the correct information for Cannonball and I needed to edit the metadata manually. (Selected 'Space Engine' in Ports menu, pressed select to bring up Emulation Station menu which allowed me to Edit the Metadata for this entry)

ok i'll double check this tonight, but from memory I putted the right bios at the right place. I'll check the md5.

Thanks

It worked!!! @BuZz your a genius thank you sooo much!!

Have a great Christmas too!

you don't need to do any tweaks or changes from default to get nes/snes running at fullspeed. in fact, i would revert all as you may have created a problem if you solved your power issues.

audio distortion/sluggishness - we need specific examples. many nes games had audio distortion/sluggishness on the original hardware, which will be the same when it's emulated.

Turns out the upstream ppsspp site shows this networking for this game in particular to be not working.

@meleu yes

Modifying the autostart.sh worked

Never mind, worked the second time with no input no output security. Weird.

@dover19 note you don't have to do this manually - it can be changed from within RGUI when in a game.

@Bradyadams
Which configure file? The mupen configure "mupen64plus.cfg" or the autoconfig file "InputAutoCfg.ini"? I recently ran into same / similar. No matter how much I edited the mupen config controller sections no changes. Even if I set the controller to manual config but no luck. The global buttons like escape I could changes.

I then found an old auto config file that had info for keyboard already setup. I copied this into the config folder and was good to go. Reading the wiki it made it sound like the auto config should be generated when you first start retropie, but I am guessing if you only config keyboard it might not.

@Gusgmb does it happen on all emulators or just some? Are you sure you're using the libretro version? Also what's your config in RetroArch-joypads? Please format it properly as described on the read this first page

@Ikyrus You could use something like jslisten to monitor for inputs, and invoke a script to switch config files.
