    I think i discovered why sound doesnt work in pifba binary and works in fba retroarch.

    pifba is an older version of fba that still uses roms with a “*m1_decrypted.bin” file inside the game zips.
    While fba retroarch is a newer version of fba that doesnt need the m1_decrypted.bin

    For that reason new version of roms (which i have) doesnt work in the old pifba.

    In some games sound works though super sidekicks etc

    i have sound in the retroarch version…. its a shame since binary version is faster…

    Mmmm. It should be fine with sound. Does no sound play with both neo geo and CPS roms?

    I only have neo geo roms. The sound problem seems to be in “more recent” games such as metal slug 4/5, and samurai showdown.

    I ran into this problem, using piFBA binary dated 3 november 2013, and my solution was to download the M1 files for the games with no sound, apparently M1 is a sound chip and some of the roms dont came with it.

    Its a shame really, since the pifba emulation is faster.

    are the m1_decrypted.bin files somewhere so you can add them to the rom? if so where? ive tried one van emuparadise but I still get a “m1-rom error” for both ms 4 and 5

    pifba is an old version of fba..

    use the retroarch version, tweak it and it will run better then pifba and with sound

    The gngeo? That doesnt work at all (In my case) or the fba version that laggs in video and sound? What tweaks are necessary other then overclocking to make retroarch fba version work smoother/better?

    input_player1_left_axis = -0
    input_player1_right_axis = +0
    input_player1_up_axis = -1
    input_player1_down_axis = +1

    audio_out_rate = 44100
    video_threaded = true

    # audio_enable = true
    # audio_driver = sdl
    # audio_sync = true
    # rewind_enable = false

    Ive tried with the above settings and with the settings that are currently blocked off but the game just lags a lot. I’ve tried the max overclock aswell and still no effect… am i missing something?

    To get sound working in PiFBA with Metal Slug 5: Google ‘Metal Slug 5 Decrypted C’ and combine the contents of that zip file with the contents of the regular ROM and re-zip as mslug5.zip The process is the same for Metal Slug 4.

    Hope this helps
