Would it be useful to also add an option like that to the built in scraper?

@Melvin.FoX exactly as @herb_fargus said. you asked about the possibility - what other answer is other than what i gave? it's possible. it's open source. that experimental core is so barren of basic features that it can't see why anyone would work on it, like i said previously. we do get a lot of people asking for this feature and that feature - my to do list is long enough with just the things i want!

just because i'm a moderator doesn't mean i represent the retropie project. i just delete the occasional spam post because i'm always on here :)

@windjammersfan you can do this yourself. I have my cps folder (really all capcom games fba supports) then you can add more entries in es_systems.cfg to have another system on the main screen. I actually have 2 cps folder. 1 for all 6 button games and one for everything else plus the first street fighter. The reason why is even though it is a libretro emulator i am using, the controllers have to be mapped manually to make any sense. And the button layout is different for 6 button fighting games and everything else

This is very odd,Had to re flash the image and everything is working again,It like it couldn't load the bios file to the Sega Mega CD weird..:D so this has not happened to anyone else then,This will teach me to copy my SD card to a image,just got to copy the videos and other images over and it done,but I will make a image of it once it done so if it happens again they will not be a problem,I think it was a space issue..So remember don't let the SD card run out of space.

Having the same issue, but I can't find any USB daemon tools under retropie setup and tools.

@seeker But, sorry, a noob question. I plug the USB with the roms (zipped), anyone in its folders, and when I turn on the Raspi, all the roms will be transferred to Retropie, isn't it? Well, I have to wait the yellow light stops blink. But, I waited near six hours :S and it continues blinking. I turnoff the raspberry. Is it normal? I'm really sorry to ask something so simple, but... I suppose I'm very clumsy. And I was looking for an answer, but nothing.
Thank you.

Just an update, I fixed the issue and now it's running beautifully. It turns out I was following the directions correctly, but I had no idea I had to remove the #. If I hadn't asked, I wouldn't have known so thank you guys for all your help!

@Rion You can still view files separately in their original folders.

I would recommend using the network to copy large amounts of data. Or use a tool like mc to copy roms manually (don't make the retropie folder, so the usbromservice to copy them triggers).

Network is easiest though.

@DanielMedStortD I believe so. Just have to try it and see :p

You should definitely try the Duplicate Files Deleter Program

Yeah, basically that. I feel daft now; I actually searched google for the terms "retropie randomizer" and all I got was stuff about splashscreens.
Thanks though, I'll give the kid mode rom roulette a try later and see if it's functional. Does anyone know if we CAN bring this feature to the normal ES mode with a script or something?

Things like FileZilla, Midnight Commander, WinSCP, etc should work fine to do that (It shouldn't matter for doing this but you may want to have emulationstation closed), but honestly, for ease of access, i'd just enable the samba sharing feature and access the roms folder from the file explorer.

Depending on how much you've scraped and whether you'd want to do it again, you could try deleting the gamelist.xml also.

Port to macos
Get the script with the following command:

curl https://raw.githubusercontent.com/meleu/share/master/noclones_fba-next.sh --output noclones_fba-next.sh

on script replace the line 47:

if ! wget -O "$gamelist" "$gamelist_url"; then

by:

if ! curl "$gamelist_url" --output "$gamelist"; then

@allenpie that's great I will send you a message at the weekend. If the Vm is Windows then it will run as for samba as long as you have read write permissions for set the directory as a network drive it will be fine. Hoping that you will be able to help fine tune the program as at the moment it's all done from my point of view! Thanks!
