@g30ff said in Goodbye fbalpha, welcome fbneo:
However, for all of the games I've tested, including Jurassic Park and Arabian Fight, setting frameskip to Fixed and the value to 1 frame, all of them play at full speed on my Pi 4.
How about the other modes ? Are they reliable too ?
-
@barbudreadmon I tried using Auto in Segasonic, and it didn't really do anything. I wasn't sure what combination of settings would get the auto frameskip to trigger, so once I found the fixed frameskip of 1 did the job I stopped mucking with the settings. I can try running a few more experiments tonight.
I should also mention I don't have any overclock settings on my Pi 4.
EDIT: As an aside:
I tried out F-1 Dream and once a race begins the game breaks. The cars are not visible, and the camera seems to start off of the track.
Another EDIT:
Tests completed. I tried out Spider-Man and Segasonic with different frameskip values.- Auto had no effect on any of the games.
- Manual with a threshold of 42 was able to make both games play well, but the framerate felt inconsistent as the frameskip was based on the sound buffer, and as such slowed down slightly when a lot of action was happening.
- Fixed with a skip of 1 frames out of every 2 frames felt the best to me personally, with a consistent framerate, and no slowdowns I could detect.
-
@g30ff for what it's worth, Segasonic plays full speed with Mame 2010 EDIT: on Pi 4. That's what I use.
-
@g30ff Thanks for the feedback about the frameskip settings, i'll see if something can be done about auto-mode.
F-1 dream works properly on my desktop computer, did you maybe enable something bad in core options, like cyclone ?
-
@dodonpachi Yep, it plays at full speed in Mame 2016 on the Pi 4. Pretty much all of the System32 games do. The frameskip settings are just necessary for FBNeo.
@barbudreadmon I haven't changed any of the core options besides dipswitch settings. The game works fine up until a race actually begins. I've tested only on the RetroPie libretro core, not on standalone. Interestingly, while the standard game (f1dream) has this problem, the bootleg version (f1dreamb) works just fine.
-
@g30ff it's indeed broken on my pi, i think i figured out the issue, rebuilding right now to confirm.
Edit : fix confirmed, thanks for the report !
-
@barbudreadmon I just built from source again, and yep, it works now! Thanks!
-
@barbudreadmon I recently read somewhere that FBneo has better NeoGeo emulation than Mame2003-plus. Is this also still true for a Pi 3B+? And if so, do you know if FBneo takes advantage of the romhack to speed up Metal Slug 2 in particular? (known as Metal Slug 2 Turbo
mslug2t)The game does launch and even recognizes the Turbo part as evidenced in the service menu, but I can't be certain it actually eliminates slowdown, as the Turbo version doesn't even do that 100% on M2003+.
-
@weirdh Over the years, i've seen users mentioning even current mame has glitchier neogeo emulation than finalburn, so it seems very unlikely mame2003-plus would do better.
The
mslug2thack has been supported in FBNeo since 2015, however i've no idea if it actually eliminates all slowdowns, if it doesn't then it seems very likely that's just how the hack actually is. -
@barbudreadmon i used MAME for years to emulate NEOGEO, starting with MAME32 (later MAME32FX) on a Win32-System and AdvanceMame on the Pi.
Once i changed to FBNEO it was clear that i will never change back.
Maybe it is only my impression, but IMHO the sound is much much better as is the overall NeoGeo experience using FBNEO.
Great project!! -
@barbudreadmon @sirhenrythe5th Thank you both for your replies. It appears I have some rom replacing to do.
-
I use FBNeo for basically everything except Sega System 32 games and CV1000 games.
-
I've been testing a bunch of different games, and I found a few bugs to report:
- bishi.zip (Bishi Bashi Championship): Glitchy graphics especially on the title screen and intro
- formatz.zip (Formation Z): The coin button does not work (works in lr-mame2003-plus)
- cflyball.zip (Flying Ball): When the startup countdown ends, the game reboots and the countdown begins again. The game never starts.
-
@g30ff thanks for the report !
bishi: this one is known, that's because the romset is a bad dump, we can't do anything about it as long as no one redump it, and the game isn't exactly unplayable so i guess there is no good reason to totally disable it.
formatz: p1 coin is working fine on my side, and i'm noticing this game has no p2 coin, are you sure that's not what you are trying to press ? Or maybe you are using the same key for coin and retroarch's hotkey ? This is known for causing issues sometimes, apparently there are ways to get around it by playing around with retroarch'sinput_hotkey_block_delaysetting.
cflyball: i'll look into this -
@barbudreadmon I didn't realize that about bishi, thanks for letting me know! As for formatz, I'm using the default controller settings, where P1 coin is controller 1 select. On this controller, I'm using the Home button for hotkey instead of select, so there's no collision with the Retroarch hotkey. I'll try building from source again to see if that fixes the issue.
EDIT: formatz's coin button DOES work, but if you do anything other than just very quickly press and let go of the button, it doesn't register the button press. It's odd, but it does work. I have seen that happen in a couple of other games, but I can't remember off the top of my head which ones.

Ok, it's weird that i can't reproduce it, but if that's the issue then i know how to fix it, thanks for the additional information, the fix will be available soon.
Edit : the fix is on git, let me know if you find any other game like this :).
-
@barbudreadmon I built from source again, and yes, that did fix the issue for me! I'll let you know if I find any other instances of this! I didn't find any other issues in the batch of games I tested.
-
@g30ff the fix for
cflyballis on git -
@barbudreadmon Built from source, and it works! Thanks!

@barbudreadmon Is there a way to remap inputs for neogeo arcade games only? By default, FBNeo has the buttons assigned as follows:
C D
A BWhile that's fine for Metal Slug and other games, I prefer the Street Fighter / modern KOF layout of:
A C
B DI've made individual remaps for certain games, but is there a way to do it for all neogeo arcade games only?
