lr-mame 2010 and 7z format

@roslof What does
7z l avalnche.7z
show ? -

@roslof said in lr-mame 2010 and 7z format:
Method = LZMA:16
that's different from my test ROM, which had
Method = LZMA2:21
Can you re-pack the file using the
7z
on your RetroPie installation ? Justunzip "$HOME/RetroPie/roms/mame-libretro/avalnche.zip" -d /tmp/avalnche pushd /tmp/avalnche 7z a avalnche.7z * cp avalnche.7z "$HOME/RetroPie/roms/mame-libretro" popd

@mitu I'll do that, but
I did figure out that using method LZMA2 instead of LZMA works... :|EDIT. This was incorrect. I had the emulator set for lr-mame...Neither LZMA nor LZMA2 generated from either 7-Zip or the Pi's 7z launch for me with MAME2010.
FWIW, here is the output for the Pi .7z:

@roslof using the same ROM (
avalnche
) I get the same error (files missing). Seems it's not fully.7z
compliant or some compression parameters are different between the ROMs. -

I guess some bug is around this, not sense to me what is going on with .7z files
-
I've looked at the libretro core repository, it doesn't seem to be supporting
.7z
. We'll update the docs accordingly, I was about to refactor the MAME page anyway.
I found out why my test was working - I traced the core and it actually picked up the.zip
file instead of the.7z
, once I removed the original.zip
, it stopped working. -
@mitu Thanks for looking at it, keeping the files in zip format :)
