lr-fbalpha now fast on PiZero & rpi1

Darksavior

@barbudreadmon lol, that build number is from mame2003...of last year.

barbudreadmon

@Darksavior Thanks for confirming. I guess we are back to step 1 then.

@lostless congratulations on pissing me off, how is it even possible to not notice you are running the wrong emulator when it is written next to the commit, and i even explained you needed to set cyclone in core options, which you obviously didn't, seriously.... no need to do more tests, you are obviously not trustworthy.

@barbudreadmon I’m really trying to help here. Im sorry if there has been any misunderstanding here. I’m no stranger to computers and retropie. I somehow made a simple mistake. How? Beats me. Lol. Anyway, I really want to figure this out. The real build number is cdc6d71. I have enabled the cyclone, restarted the emulator and did notice a difference in neo geo games. Turned on frameskip to 1, and it’s almost full speed. So the cyclone driver is working, just not full speed. And that’s not a complaint, but a report on the status of this emulator on a pi zero. I really do appreciate your efforts.

barbudreadmon

@lostless Might be that the neogeo driver had too many accuracy fixes over the years then, because on my rpi1, neogeo through the old lr-fbalpha repository (now known as lr-fbalpha2012) was close to full speed (~60 fps with some slowdowns iirc). Might be a good idea to backport the cyclone stuff to lr-fbalpha2012 actually.

What about cps1/cps2 ?

lostless

@barbudreadmon cps1 and 2 (tested strider, final fight, and cadillacs and dinosaurs) are almost there. There are small moments in which they are running at full speed, but typically are running at around 90-95% speed. Soooooooooo close.

@lostless i'll notify fbalpha2012 maintainer about this, perhaps he'll be interested in porting cyclone.

Hi everyone.

I decided to give the Cyclone (in addition to the frameskip: 1) option a try, and I have to say that it does improve performance quite a lot.

I'm experiencing issues with the load/save state. When I try to load or save the emulator crashes, and I'm back on Emulationstation.
I tried to delete previous save states, and/or use the autosave option without any success.
When I try to use the autosave option, it looks like it is only able to save it once.

I ended up testing different options, and I eventually, I was able to get things running correctly on a previous version of lr-fbalpha.

To be more specific:

It works fine on 1.7.5 - lr-fbalpha v0.2.97.44 - cfbe1e1
it breaks on 1.7.6 - lr-fbalpha v0.2.97.44 - bd60621

I tried everything on a fresh Retropie image to make sure nothing else was interfering with this behavior.

Any suggestion?

Hi @barbudreadmon,

I'm not sure if you are the best person to ask this question to, but since you started this thread I'm going to give it a try.

I have been using the Cyclone: enable option and setting frameskip: 1 on FB Neo on Retropie (PiZero), and I surely see a substantial improvement in performance.
As I wrote in my previous message from last year, when I try to load/save a game, emulationstation crashes and it goes back to the game list.

Yesterday I saw that there is a new version of Retropie (Version 4.5.1) available, and in the change-log it's mentioned that it now supports Cyclone for improved performance.
I tried it from a fresh install, but sadly I get the same issues.

Do you have any suggestions that could help me in debugging and hopefully fixing the issue?

Thanks for any help you can provide.
