Edit a "recalbox" folder and boot image

HiagoMendes

I'm trying to change the boot image (logo) and the "recalbox" folder is a compressed file.
In Raspberry it is easy to change using WinSCP, but how do I change on Batocera-PC? I do not have raspberry!

Screenshot: http://prntscr.com/erlhod
This file has 426mb and I wanted to edit the "splash" in the files inside it.

Could someone help me with a tutorial?

HiagoMendes did you try to edit with notepad++ ?

It's not possible .. I tried but i lose the game. I'm waiting an update with the possibility to change image.

I don't understand the problem.
you can modify the image, but you cannot modify the file recalbox.
1) just boot
2) mount -o remount-rw /
3) do any modification on /
4) /recalbox/scripts/recalbox-saveoverlay.sh

the splash is in /recalbox/something.

I do not have a Raspberry Pi, I'm trying to modify the PC version. Could you send me step-by-step instructions?

nadenislamarre

there are the same for rpi, odroids, x86 versions.

When I try to remount as rw the the / partition :

mount -o remount-rw /

I get the following message

mount: can't find / in /etc/fstab

I would like to try to play with the XU4 cloudshell and try to find how to get data out of the screen.

nadenislamarre

mount -o remount,rw /

yaazzz

Oh yes : this is better.
When I try to edit etc files it say read only whereas I have no error message when trying to re
mount the partition.

@nadenislamarre is possible use unsquashfs and mksquashfs for add a new core?

Scofield

I have the core ready and working in recalbox, like to add it in batocera without having to compile

nadenislamarre

perhaps, but it is making things complex when where are simpler.
just mount -o remount,rw /, copy the file and save the overlay with recalbox-saveoverlay.sh

Scofield

i try, but return a error
rsync: write failed on "/overlay/saved/usr/lib/libretro/mame2010_libretro.so": No space left on device (28)

Scofield

and
rsync error: error in file IO (code 11) at receiver.c(393) [receiver=3.1.2]

I 've tried but if i want to delete file logo-version.png the system says: can't remove read only file system

If i want to copy a new file called logo-version.png the system says: can't create the file exists

I copied my image in recalbox/share and then i've tried to copy from this location to /recalbox/system/resources/splash but not work

reigelgallarde

do
mount -o remount,rw /

and everything in that line is important... do not miss the comma, or the slash..

nadenislamarre

@Scofield i've sized the overlay to a 50 or 100mb size, i don't remember.
the aim of the overlay is just to customize some files, not to rewrite all ;-)

Scofield

nadenislamarre I'll try add another core, snes2010 just for a test, I had changed recalboxintro and it works fine, with advmame and fba almost all games in my list on raspberry are ok, thank's.

cap_supositorio

nadenislamarre I cant edit the Batocera Splash, can i change the intro video?

When i try to save says:
Making /boot writable...
Mounting the overlay file...
mount: mounting /dev/loop1 on /overlay/saved failed: Invalid argument
mount: mounting /dev/mmcblk0p1 on /boot failed: Device or resource busy

nadenislamarre

why do you need to update the cores ? the one provided by batocera are not ok ?

Scofield

Some games of mame only work in the mame2010, in raspberry pi3 version with advmame some still do not work, in the pc version all the games work with mame0139

Scofield

Advmame in the batocera is 1.3 or 1.4? it's maybe simpler to change the my romset again
