Retropie 4.6 - Pi 4b - Zip problem snes9x

[Tounet]

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

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.

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