Error edit system - Odroid XU4

[Scofieldi]

I can't change system, try use mount -o remount, rw / with putty but it doesn't work, trying add core for mame, mame2010 in usr/lib/libretro and change es_systems.cfg

Return massage "Ready-only file system"

This core works in Raspberry Pi 3.

Sorry for bad english.

ok, i found error

'In other word, if you've an xu4, you'll not be able to customize the system itself without converting manually the recalbox file (squashfs) to a basic ext4 file (loosing the compression). '

I try this, thanks.

However, note that in your case, the simplest way,
is to copy es_systems.cfg to /recalbox/share/system/.emulationstation/es_systems.cfg while it is where it is taken in priority if found to override the system file.

cp /recalbox/share_init/system/.emulationstation/es_systems.cfg /recalbox/share/system/.emulationstation/es_systems.cfg

I managed to make some changes through es_system, add .BIN files for psx but I could not add the core mame2010, I saw that there will be advancemame in new version and this will work for me.
