@mitu Thanks a lot!!! I changed the hostname and all cores are installed correctly

@backstander Never has purple been so perfectly personified.

Just my findings: commit 0343e3dbd8a22f64698e824e30b08e0887d77b6b Author: retro-wertz retro-wertz@users.noreply.github.com Date: Sun Mar 4 21:47:52 2018 +0800 Add missing variable to save state This is the commit that breaks the loading of existing state files from old pi's. And for anyone's future reference: here is the github issue regarding it: https://github.com/libretro/libretro-fceumm/issues/215

@montecore >Sounds like there's nothing that can be done Well, you could manually recompile it from an earlier version to get back to where it was but as far as converting the savestates I'm not aware of any method

@mediamogul it wouldnt work on the nes. I would remove all the circuitry in it and install a small board like raphnets 12 buttons to usb board making it a usb power pad. Or in my own personal case, i might just wire a 15 pin cable so i can just plug it into the connectors on my ipac.

This has been added to the NES wiki: https://github.com/RetroPie/RetroPie-Setup/wiki/Nintendo-Entertainment-System#how-to-setup-turbo-buttons-for-lr-fceumm

@TPR I change my settings inside the retroarch gui in-game. Should be under Quick Menu\ Options

Yeah I confessed. Thanks, I've learned about getting in the RGUI with a hotkey, which I didn't know about before. Thanks again

The reigning theory is that the issue comes from missing HEADERS. The NES requires Headers in the ROM or it won't boot. However, just recently posted information suggests that unzipping the ROM may solve the problem. I've not been able to test this myself since I'm troubleshooting controller issues right now. Please let everybody here know if unzipping works for you!

I tried them both now, and nestopia definitely has the better audio emulation. Mario 1 dying sounds so inaccurate in fceumm. In the past, nestopia had this strange sound bug every now and then but I no longer hear it. Though, maybe the fceumm audio accuracy might be improved in the future? And can I recommend having the Unsaturated or Nes-Classic Palette as default? They look much better on both emulators.

@laephis I had a issue were my tv would only use pal 50hz even when I ran a usa nes rom .... Hence I had stuttering and slowdown try a pal game see if that runs fine if so that's your issue. I had to change the .config to force my tv to find 60hz maybe this is the same issue. ^^^^^ issue solved I speak through my hoop

@BuZz Thanks! So the (re)installing process remains necessary, but now we can do it from binaries, right? And on RetroPie 3.8+ it won't be necessary, right?
