Actually, it did work but instead of adding these lines I uncommented the same in the config file and just changed the values. Thank you very much for you fast and adequate response.

@IowaBrewer I know its a bit late but i had these issues with my old pi2 it was the cheap nasty usb cable i was using. I bought a decent one and my power supply's worked well. The same thing happens with the dirt cheap hdmi cables as well sometimes.

@RonsterMonster There is no official image. At the moment, you can clone the repo, but it's different from what ETA Prime did. Install raspbian lite. Install Git. Then type: git clone --branch fkms_rpi4 --depth=1 https://github.com/RetroPie/RetroPie-Setup.git Enable the GL (Fake KMS) driver in raspi-config If you're not familiar with a manual install, go here: https://github.com/RetroPie/RetroPie-Setup/wiki/Manual-Installation I'd really hope for test images soon. Basically all the libretro emulators work. The rest are hit or miss.

@mitu Thank you, this worked.

You mean the DualShock 4 controller?

@TheGamer What games in particular are you having issues with. The original NES had lots of slow down, and emulators are doing exactly what the original NES did. If the sound doesn't sound choppy, but sounds normal, its just the original slow down in the game. As far as the EU vs US, EU games ran 4% slower.

@the496rocket please, try to fill the form in the read this first post. There must be something wrong in your setup. RetroPie on a raspi3 with decent peripherals can run smoothly any game from the 8/16-bit era without any tweak. Just install, config input, put your ROMs and play. [Footnote: OK, maybe 3D games, like StarFox (SNES) and Virtua Racing (Mega Drive), can stutter a bit. But the games you mentioned should work just fine.]

@kekke2000 said in Master System Lag: I'm a total noob at this. Got the Pi today and followed a guide to install the emus. NES, SNES and Genesis works perfectly. But on SMS there is a small latency like 0.3 seconds or something. It's hard to do precision hits and jumps. Is there a simple setting somewhere that could possibly fix this?! First: https://retropie.org.uk/forum/topic/3/read-this-first Second: Turn your TV to gaming mode. Connect the HDMI from the Pi directly to your TV and bypass any soundbar etc. Often this latency is caused by post-processing from a TV, AV receiver, soundbar, or other device that the HDMI signal is passing through.

@edmaul69 haaa then it can feet! :)

I can get in to the castle just fine, but selecting levels, they just end up super lagging and no textures. pi3 is just not powerful enough to run it.
