Retropie 4.6 - Pi 4b - Zip problem snes9x



  • Hi there,

    I'm new to emulation, but not to gnu linux, after some days of testing, i have all my roms who works well except in zip file (or 7z) for snes9x.
    The files are on the sd card (not mounted from usb or nas)

    It's not a naming problem because i had remove all space and special characters (to be sure)

    My conf :

    Pi Model 4 B
    Power Supply used: (If using a Pi) : 5V - 3 A
    RetroPie Version Used (eg 3.6, 3.8.1, 4.1 - do not write latest): 4.6
    Built From: Pre made image from PINN
    USB Devices connected: mouse keyboard
    Controller used: 8bitdo
    
    Error messages received: 
    [libretro INFO] Try 'force no-header' option if the game doesn't work
    [libretro INFO] "y<L____V_|vC____!,__Yp" [bad checksum] LoROM, Corrupt, ROM, NTSC, SRAM:Corrupt, ID:_m__, CRC32:7FABE0EC

    Emulator: Retroarch 1.8.5 with snes9x
    

    Log found in /dev/shm/runcommand.log with zip : https://pastebin.com/Swmx36wZ

    Log found in /dev/shm/runcommand.log without zip : https://pastebin.com/q9SQ54Bx

    I don't understand the bad checksum message as the rom works well outside the zip. I have try many times to recompress the zip, even with store only (nocompress) option.

    retroarch 1.8.5 is build with zip and 7zip support as the --features show.

    Is this a common problem ?

    I could doing more test or debug.

    Could be a zip compatibility issue. What's the output of

    zipinfo -vv /home/pi/RetroPie/roms/snes/SuperMarioWorldEuropeZip.zip
    


  • I finally found the problem after searching on google, but i don't understand
    After renaming all flc files in the zip, no more problem.

    So the rom with flc or mgd work outside the zip, but in the zip only flc ?

    If someone have an explanation.

    I don't understand either - you renamed them to what ?



  • All my snes rom have mgd file extension in each zip. After renaming all these rom to flc in the zip. No more problem...
