Some emultors/roms running slowly on my Pi

@jimd0586 the slowdown stuff is tricky as often it's just the original hardware. e.g. metal slug games have a lot of slowdown when played on a neogeo, so that slowdown also appears in emulation. it's not your hardware failing to perform. the only way to avoid it is with hacks in the emulator.

i'm not sure if your other examples have slowdown in the native hardware but it's very possible.

also as a general rule, the default settings we have in retropie are almost always the optimum for your hardware. if there was some magic option to make things better we would use it by default :)

Thanks Dank, I appreciate the input. I'll deal with it.

Any idea with the Open GL problem and not being able to access retropie? Should I repost with a new subject?

dankcushions

@jimd0586 if you've done a bunch of stuff that you can't remember it's difficult to revert! i would suggest running a full retropie binary update again.

The opengl desktop acceleration is incompatible with retropie. Run raspi-config and disable it.

@BuZz

Any idea how to disable? Can I do it from the command line? I cant even get into retropie/emulation station.

@dankcushions
Ok. Thanks. How would I do that from the command line?

BuZz

@jimd0586 type raspi-config

Got it. Thanks Buzz. While I am sure that Dank is correct, that some roms and emulators will run slowly on a pi, any idea why my pi 3 is running slowly? I hear that pi 3's can run N64 roms. Are there individual rom or emulator settings that might help?

BuZz

@jimd0586 what is running slowly apart from those mentioned? N64 isn't perfect and some games have slowdowns for example.

@BuZz

Honestly, the only emulators that I play are neo geo, MAme 2003, and SNES

@jimd0586 please give me an example of something that is running slowly.

jimd0586

Ok. Well, the SNES emulator should be able to run on a Pi3 easily enough. The best example I can give is Super Mario World Allstars + World. But generally, I imagine that the Pi3 should be able to run the SNES emulator without problems. I wonder if my RaspiATX card that controls the power is draining too much juice from the Pi3 thus reducing performance. Is that a possibility? I do have the switch that controls the pi from the board as an LED switch... ie it uses electricity as well.
