Hello, I have the same problem but delete all the images and now it works well, I do not know if it helps you
sorry my google translate english

Thx @rockaddicted !!! Even having this unexpected issues, I really appreciate the new release cycle of recalbox. 😀 to be updated and remove old emulators, retroarch etc it's the way to be.

I managed to restore the gamelists from an old backup and at least now i can get to the games listed on the old gamelists, but when I try to update them it simply ignores the files present in the sd card. Sorry but this seems like a bug and I simply can't get it to update. the es log simply says it parses the XML files but it doesn't seem to look for the rom files in the card.

In case anyone needs it:
I've used this it works: PSX cue Maker

@acris hmmmm pas très pratique alors ....

@Substring I don't think so unfortunately. I was following a discussion in the retropie forum a while ago, but the outcome wasn't very big I think

@acris ok, thanks!

I've seen different threads where people have done that. Use the search function and you'll find it.
Nachtgarm didn't give any instructions, it was just an idea.

@0zzy recalbox generates configuration files on the fly dependng on your plugged pads

@pillemats

Since version 4.0.0 beta 4 we've removed the simplelight theme and made the recalbox theme the default. You can download all officially supported themes HERE.

ok you mean /recalbox/share_init/system/.emulationStation/es_systems.cfg
I made a copy in /recalbox/share/system/.emulationstation
but once restarted, i do not get in emulstationmenu/.. advanced options/ mame the choice with two values defined here for instance :
<emulator name="libretro">
<cores>
<core>imame4all</core>
<core>mame078</core>
</cores>
</emulator>

so i am not sure its actually read...

btw i've found where the command is composed and launched , redirection of standard output could be put here..https://github.com/recalbox/recalbox-configgen/blob/4.0.0/configgen/emulatorlauncher.py#L151

I answer to myself. Turgografx 16 rom files are .pce (PcEngine), so they go to that folder :)   That's all!

Sorry, i use my sd card for my roms. I can't help you :/. Look in the forum. they have différent topic about usb drive... Hop that help you :/
