@GreenHawk84 - If it helps troubleshooting here's a small script that outputs the speed in a more user friendly format i.e. 900 MHz with CPU/GPU temps like 65°C. I use it with watch if I suspect throttling by the governor, heat, power, etc.

I open a Putty session on my PC and run watch and whatever the script is named so I can monitor the speed and temp in real time while playing on another monitor/TV. It does require an extra device and connectivity but it's helped me a few times.

#!/bin/bash
cpuSpeed0=$(cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq)
cpuSpeed1=$(($cpuSpeed0/1000))

cpuTemp0=$(cat /sys/class/thermal/thermal_zone0/temp)
cpuTemp1=$(($cpuTemp0/1000))
cpuTemp2=$(($cpuTemp0/100))
cpuTempM=$(($cpuTemp2 % $cpuTemp1))

gpuTemp0=$(/opt/vc/bin/vcgencmd measure_temp)
gpuTemp0=${gpuTemp0//\'/°}
gpuTemp0=${gpuTemp0//temp=/}

echo
echo CPU Speed: $cpuSpeed1" MHz"
echo
echo CPU Temp: $cpuTemp1"."$cpuTempM"°C"
echo GPU Temp: $gpuTemp0

@GreenHawk84 im running into the same issue since the update. Sf iii feels like it’s running ok, and most probably will not notice, but it is running slower at about 55-60fps with some minor audio pops and clicks. It’s trying, but the accuracy updates just push the pi a tad over the edge. I switched to fba2012 and it’s running fine on that.

Firstly I'm a little confused by the 'running slower at about 55-60fps' part. Are you using a Pi or something else? Because by default the emulators are set to 60hz vertical refresh rate, meaning you won't get anything more than 60fps, and therefore 55-60fps is a pretty good speed.

Anyway I decided to test SF3 (New Generation, 2nd Impact and 3rd Strike) on my Pi, both before updating FBNeo from source and after.

Pre update, I was getting on average 58fps on all three games.

Post update, my FPS actually increased to a fairly solid 60fps, perhaps dropping every so often to 59.

So if yours is not working, something is interfering with your emulation, but I don't think it's the emulator itself.

GreenHawk84

@thestarglider when I pull up the FPS counter in SF3 I am seeing consistent dips to 58fps (occasionally down to 55fps) causing slight [constant] stutter in the motion. I am also hearing similar audio scratchiness. So far this is only with SF3. I fresh installed Retropie not too long ago on an RPi3B+ without adding anything else. I am totally lost on why my B+ is performing worse than anyone else's.

thestarglider

@GreenHawk84 and again, since the target speed of the Emulation is 60fps, I'm somewhat skeptical that this stutter is purely down to a drop of a couple of frames a second that really no human is going to notice with their eyes. Something else is interfering with your game.

The game actually run at 59.583393Hz, but with RA's fps counter not being perfect you'll only see an approximation.

Anyway, yeah, the pi3b+ is definitely able to run at full speed the 3 sfiii without OC nor frameskip, including sfiii2 with widescreen (for me), i don't understand what's the issue for @Darksavior @Lyle_JP @GreenHawk84, at this point i think it might be a hardware defect.

Hello, first of all I don't want to complain. You do great work, but is there something wrong with my setup or has someone else experienced the following?

Food Fight ran fine with FBA previously, but when I upgraded to FBNeo I lost the ability to play Food Fight. I didn't notice earlier because it's not a title I play often, but I was recently going to try to make the controls similar to Robotron 2084 only to find that the game no longer played in "Final Burn" (my arcade default). The title never played in FBA2012, FBNeoGeo, and MAME on the RPi. FBA was the only emulator that worked. Is something corrupt with my ROM? Just curious. Thanks.

The game is working fine so i guess you are using a bad romset.

Riverstorm

@IanDaemon - Food Fight (foodf) should be working in mame2003 and mame2003-plus. With mame2003-plus I think markwkidd created a "bootstrap" which basically generates the .nvram file on the fly during game launch or it hangs and looks broken. It's seamless to the user. I don't remember if mame2003 has the bootstrap code but I know you can copy the .nvram file over from m3plus to 2003 and it works fine.

There's several games that need .nvram files or they don't boot correctly so I keep clean copies with the ROMs for new setups. I've never needed to do that for FBNeo though as they have always just worked.

Because on latest mame romsets (the ones FBNeo uses), the nvram is part of the romset for games that need it.

@barbudreadmon - Thanks for that it makes things a lot easier! :)

GreenHawk84

Okay so upon replacing the generic power supply with an official Raspberry Pi power supply, it seems the game runs a lot better than before. I still think that FBA2012 is working a little better, but apparently I was using a bunk PSU.

Yeah, hardware defect was the most likely suspect from the beginning, assuming you were really using default settings.

@GreenHawk84 said in Goodbye fbalpha, welcome fbneo:

Use whatever you want, as far as i'm concerned the pi3b+/FBNeo/cps3 combination is perfectly smooth on my side, and i prefer accurate emulation when available.

GreenHawk84

False alarm, my 3B+ still runs SF3 poorly. Everything else is fine. I have installed fbneo from source multiple times, defaulted my settings in retroarch (even though I never changed anything) and even turned off my simple overlay of side art for the game. Nothing works for fbneo (SF3), but fba2012 is pretty nice. I think I am going to give up on this for now, maybe something will improve for me later.

dankcushions

@GreenHawk84 how did you default your settings? there’s a right way, and a wrong way...

GreenHawk84

@dankcushions I just went into the Retroarch UI and selected the option to reset.

dankcushions

@GreenHawk84 that’s the wrong way, hence you won’t see it in any of our docs. it gives you retroarch defaults, which are very different from retropie defaults, and probably include rewind, and a bunch of other non-performing features.

right way: https://www.reddit.com/r/RetroPie/comments/7gupd2/how_do_i_reset_retroarch_settings/

but tbh, now that you used that option i don’t know what your .cfg setup will be like. you’re on your own...

HACHI201

My fbneo can't run, he will return to the selection interface, my device is Raspberry Pi 3b+, do you know how to solve it?

@HACHI201 open a new topic and provide the information asked in the Read-me-first topic, linked at the top of the forum.

Imho, usual "i didn't bother reading the arcade documentation and don't know what's a romset" crap.
