What is important is the information you should include in your post (pi version, where you got Retropie from, what version, etc.).

MAME is a complex subject. It is a project that has been in development for many years and the supported filesets are updated with each release. You cannot just take a MAME ROM and throw it at a random MAME emulator, it has to match the version of MAME that the emulator is based on. On Retropie there are a number of different MAME packages and each supports a different romset.

If you want to play a specific game, you need to get the ROM in the right version for the emulator (a list of romset versions for each emulator are in the wiki).

@Joshua2005777 The default view in the File Manager (Midnight Commander) should show the user folder. Assuming you are using the SD card to store your files, your ROM files should be located inside the folder Retropie\roms\<System Name>.

@Shootersf I have only tried PiFBA briefly. I use lr-fbalpha as I use a Pi3. Does PiFBA have a config file that can be edited and saved? It may well stick if you go that route.

@adamLazar no development is happening on pifba.

If you're using a raspi3 you should try lr-fba for neogeo emulation. It's a lot easier to configure, etc.

Maybe you'll need to find the "FB Alpha 2016 Reference Set" somewhere else (we don't share ROMs/links here) to get the compatible ROMs.

@mediamogul

pifba. when i start a rom it instantly shows the black 330 mega screen

I use lr-fbalpha for most arcade ROMs. My guess is that you need newer ROMs. Update your image to the latest Retropie and then find some new ROMs.

@Allo said in MULTIPLE buttons for an action? (PiFBA):

Ok, so I've downloaded the correct ROMs and now running lr-fbalpha. I've entered the menu to customise my buttons, but I still can't find a 3 punch/3 kick option!

Where do I find this 3 punch/3 kick option?

quick menu > options

or

quick menu > controls

i think here should be something like that

@eVenom said in Issue with PiFBA and PS3 controller:

How are you guys not using PiFBA?

Because lr-fbalpha runs everything using the v0.2.97.39 romset.

Just a quick update on the situation.
As barbudreadmon recommended I updated my romset for the games that would run only with the pifba emulator and now I can play them with the lr-fbalpha emulator! Which again doesn't need any further controller settings since I had everything done already.
It did not solve my issue with the pifba but updating the romset made it unnecessary to fix.

Thanks again for the quick help. I think I'll go grab a beer and start playing.
Cheers.

@bilufe said in Run games on lr-fbalpha:

Roms work on the pifba, but not on lr-fbalpha.

https://github.com/retropie/retropie-setup/wiki/Managing-ROMs

switch to the lr fbalpha or lr-fbalpha 2012.

@rbaker gotcha, FBA is now working with a v0.2.97.39 romset and the Dualshock. Thanks.

@suprjami thanks. yeah, since there's no stipulation of overclocks in the compatibility list, i think they really need a separate column for pi zero.

This emulator works perfectly for the PiZero but I couldn't sort out the controller settings until I found this old thread.This worked perfectly after using the update note from Polezi, thank you and huge thank you to Meleu!

@ultranano has this been fixed? I also have a DragonRise Joystick and up and down is inverted. I cannot switch the up down wires without desoldering the connector. It's just a hassle...

Is there another way to invert the axis?
I read somewhere changing from JA_LR_1=0 to JA_LR_1=-0 but this didn't work.
