PiFBA released - Final Burn Alpha arcade emulator

[bidinou]

Heh, I changed my mind actually. I was about to try to use the GPIO, but I realized, again, the input lag only annoys me in some emulators. For instance, I cannot notice the input lag in MAME4ALL. Or it's so low it's acceptable. However, it's very visible in piFBA (try GigaWing !! You'll have trouble dodging bullets . So I think I'll rather wait for improvements in the emulators. I would definitely contribute to a bounty / kickstarter to improve the state of emulation on the Pi.

As I said on another thread : the lack of CPU power is not at fault, IMHO, or it's just one variable. For instance, DoDonPachi is slower in Mame4ALL (have to use the turbo mode !!) but it's more playable than in piFBA as there is much less input lag !!

I know metal slug does have slowdown as this was present in the arcade i.e. the animation became slower but the music was still in time and didn't stutter like treacle. The difference with Metal Slug 3 is that the sound stutters and its as if the Pi is having trouble with it. I'm not sure why as I'm overlcocked and all the others work fine. Very strange!?

Hi did you manage to solve this at all? Have come across the same issue, it's definitely the Pi struggling

Hello!

I have a question regarding multiplayer support.
I managed to get two gamepads working but I can't get three to work :/

I tried adding the following to fba2x.cfg:

Code: Select all

A_3=3
B_3=1
X_3=2
Y_3=0
L_3=4
R_3=6
START_3=9
SELECT_3=8
#Joystick axis
JA_LR_3=0
JA_UD_3=1

but to no avail. Is 3 player mode supported at all? I tried searching but can't really find any information.

Welcome to the Forum! Unfortunately PiFBA is 2 player only at this time.

I don't think this is active development at all unfortunately.

[rambopie]

Awww too bad. I'll try to get those games working for mame4all-pi then.

Also with FBA, I'm not sure how many Arcade Boards its compatible with that actually have more than two Players!? (i.e SNK's Neo-Geo MVS, Capcom CPS1/CPS2 and Cave 68000 Hardware is generally 2 player only as far as I'm aware, but there are other Chip Sets it runs).

[rambopie]

Looking at https://code.google.com/p/pifba/source/ ... d55b6fa0e2 fba supports Cadillacs & Dinosaurs (3 players) and the Dungeons & Dragons (4 players) roms, but apparently only for two players.

Oh well, one can't have everything

Does the board A powerfull enough to run all pifba games?

[lsalcedo]

im trying to config fba to play with 2 players but i still had no luck.
im using a xin mo enconder, got the input from jtest and this is my code:
---------
[Joystick]
# Get codes from "jstest /dev/input/js0"
# from package "joystick"
A_1=0
B_1=1
X_1=2
Y_1=3
L_1=4
R_1=5
START_1=6
SELECT_1=7
#Joystick axis
JA_LR=0
JA_UD=1
#player 2 button configuration
A_2=10
B_2=11
X_2=12
Y_2=13
L_2=14
R_2=15
START_2=16
SELECT_2=17
#Joystick axis
JA_LR_2=2
JA_UD_2=3
--------


any ideias? thanks,

Should be fine, performance wise there is no difference between the Model 'A' & Model 'B' RPi, just one less USB and no LAN. The Memory difference (256 instead of 512MEG) shouldn't be a problem I have a Rev1 Model B (also 256MEG), Garou: Mark of the Wolves runs fine and at 688MBit is one of the largest Neo-Geo ROMS.

[thak]

Ok great, thanks for your answer Welshy

I think i read somewhere that pifba and/or pisnes reconize only two axis and 16 buttons (or maybe it was for another emulator... But definitely related to raspeberry pi)

pifba

August 5, 2013:

Added two player joystick support
Fixed frontend neverending quit with joysticks

[batcha]

Hi, i'm trying to make work my ps3 bluetooth to PiFBA.
It works, but can't make my DPAD buttons work, left analog is the axis.

It's possible to change that, playing some games with the analog stick isn't good enough.

Thanks

[KitchUK]

I noticed some larger roms like Garou and SNK vs Capcom have performance stutters (i.e. frame drops below 60fps). Is there any way to alleviate this problem or are these games going to always have issues? My current setup is:

ARM=1000
CORE=250
SDRAM=500
GPURAM=128
OVERVLT=4

[bidinou]

It's pretty strange, I'm not sure to feel this famous input lag anymore, or not that much. I wonder if that's my perception, or something related to my setup, well...

Is there a way to save highscores in pifba, guys ? It's pretty frustrating not to be able to save them in shmups

Thanks !

I was wondering about this too. Is there a way to keep the dip switches/bookkeeping intact? I always find myself switching to FREE PLAY in the service menu. I don't particularly enjoy having to insert an imaginary coin everytime I want to play.

[expandables]

Is there a way to play online on pifba?

[mancity]

Quick and easy question (please).....

Can I add 'COIN' to a joystick button?

Would I just add the following under joystick?

COIN=x

x being whatever the joystick button is

[mancity]

Iv'e had a good go of this last night and tried quite a few ROM's and for Metal Slug, iv'e found 1 & 2 work fine, but 3 & 4 have no sound and 5 & X do not load (Go to a black screen momentarily and then exit back to FBA).

Has anyone else noticed this with these games? The PiFBA list shows these games as all working too which I thought strange...

Worked out that 'SELECT' was actually coin after messing with jstest, so that's all good.

Does anyone have any good scanline settings? I followed the settings on the PiFBA site and the scanlines are more than 1cm thick, so dont look too good?

Finally - Is there any way to hide neogeo.zip from the front end?

[thak]

Hi mancity!

I used to have problem too with neogeo roms (lot of them actually...) and 99% the rom itself was the problem.
Did you try other zip of the same game? (from other source for exemple)

As for the neogeo.zip, i use Piplay and in the front end bios doesn't show.

And for the scanline, i can't help you, luckily i never had to change the config here.

Hope i help you somehow

[mancity]

Hi ,

I know these ROM's work because ive got them working on MAME in Windows.

Anyway, i've tried 3 different ROM's for the games and 3 different neogeo.zip's and the result on ALL of them is as follows for Metal Slug games -

mslug - Works fine
mslug2 - Works fine
mslug3 - Loads to main screen for half a second then exits
mslug4 - You get MVS error during boot then game works, but no sound
mslug5 - You get MVS error during boot then game works, but no sound
mslugx - Works fine

Can anybody confirm if this is the same for them using piFBA please?

[welshy]

Hi ,

I know these ROM's work because ive got them working on MAME in Windows.

There's the rub, it depends on -
1. Which version of MAME your running
2. Which revision of the ROM is required

I have Metal Slug 1, 2, 4 & X running in PiFBA, as suggested 3 seems to generate a 'Segmentation Fault' but others here have reported it working with the correct ROM revision, and/or a combination of ROM files. If you run FBA through command line in a Terminal it should report what is missing/required, but sometimes its just 'Trial and Error' with Emulators!

[mancity]

Thanks for the reply.

Can you tell me then, what version of MAME piFBA uses?

[welshy]

Thanks for the reply.

Can you tell me then, what version of MAME piFBA uses?

Unfortunately I haven't discovered WHICH version its based on (although it uses MAME as a base). I have edited my above post, try running FBA through command line in a Terminal, it may provide you with the information required on whats missing from your ROM files.
