@herb_fargus I know this is an old post, but thanks for posting this hefty tidbit on emulator speed vs accuracy. It was very educational and an enjoyable read.

@ayeye try updating the emulator from source.

I understand the symptoms may be the same but often there are multiple reasons for an issue, so a new topic with full information about your set-up helps. Also the problem in this topic was solved. Please follow the guidance in the link I provided.

Some other things I noticed when I booted up the Pi 3 tonight and additional information and corrections:

Upgraded form 3.8.1, not 3.8.7 (sorry about that). Burned from my PC using Win32DiskImager. It's happening on ALL of the emulators, not just SNES, and I tried NES (Contra, Mega Man 2, Castlevania 3: Dracula's Curse, Super Mario Bros. 3), Genesis (Sonic the Hedgehog, Earthworm Jim, Mortal Kombat), 32X (Virtua Racing Deluxe), Sega CD (Snatcher), and PSX (Crash Bandicoot, Castlevania, SOTN, and Tekken 3). Same audio lag by about 1-2 seconds after the motion. Music also lags behind, but it's harder to catch because of the input from the sound effects. Just to make sure it wasn't the R-Pi 3 in question, I had another Pi-3 with another SD card running a different software on it and removed the SD card from it and stuck the same 128 GB SD card inside the R-PI 3 and powered it on (using Canakit parts from one of their many R-Pi 3 kits they sell on Amazon with the 2.5 A, 5 V power supply). and same problems occurred. The garbled sound in the main menu for selecting games and lags behind in the moving of the highlighter from game to game (sounds like static), and even through selecting consoles in the main menu. Also, I notice when the R-Pi 3 is powered down, either through the Emulation Station shutdown procedure, or by the In-Line Power Switch I have connected to function as an on/off switch for the R-Pi 3, the sound volume always goes back to 0% when I power on the unit.

Just my takes on the situation. Anyone else notice this?
