Do you have a USB-keyboard attached to your Raspberry?
If yes, try this:

Thank you all for the advice. I will read through the suggestions and do some testing this weekend. I was on travel for work unexpectedly.

Fantastic! Thank you my friend :D

Going to bump this just to keep it on top just in case its hard to find.

Hope your sorta fruit let us know if you are. I would pm you my email but I don't think that's possible

if you don't ever scrape your roms it's much faster, but once you have a large gamelist full of meta data, it takes a long time to save (eg to save the last played time, it will have to save a huge file with all the other meta data). One of the downsides of the current xml storage (the unstable branch of ES was to resolve this, but needs some more work still)

That is by design currently. Just ignore them :-)

Thanks a lot, I didn't know about the es_swap_a_b = "1" option. It's ok now I feel better :)

@josvk said in MAME/FBA roms question:

Hio @dankcushions , thanks again.

Almost there ;-) I'd rather have one folder, so I'll put all my roms in the Arcade folder, including the neogeo.zip bios file. Would you suggest I use the 0.173 (fba 0.2.97.38) bios file, since it is the most recent?

it depends on what emulator you're using to run neogeo games in that folder - lr-fba-next will only work using the 0.2.93.38 neogeo.zip, and lr-mame2003 will only work using the 0.78 neogeo.zip.

I'll use fba-next as the default emulator, and use runcommand to play some 0.78 roms (that aren't in the fba 0.2.97.38 set) in mame2003.

Please verify one final time whether my thinking is correct :-)

hope that helps :)

consider to use a NAS if you have tons oft ROM data.... Whatever you want :)

Ok so I got an old MicroSD Card to install RetroPie on, Flashed my 8Bitdo Controllers back to 1.68 and started fresh, everything worked fine though a couple tweaks had to be made to the es_config as ES would not associate the mapping to the "a" button correctly. After doing this I copied the "all" to my desktop, swapped back to the old RetroPie and deleted everything that "wasn't" in the new setup, then proceeded to copy those files over and verify all the configs looked correct yet still no dice.

I finally said screw it, copied over the Gamelists and downloaded images and just reformatted the card and started a new install, as of now both controllers work fine (with the exception of MAME) registered on 1.68, So why i never did solve the issue with the old setup (must be a config file somewhere else on the system we simply aren't accounting for) The problem has been resolved by starting over. I have been careful not to mess with the settings menu or do any sort of updates to prevent it wanting 1.69+ to function properly as it did last time,.

@kaitlin4599 yep it runs just fine. Just replace the doom wad with the chexquest wad. Eventually the wad selector will be improved so you don't have to manually change things

I found this guide for you in French:

It's a video guide so it's easier to follow. I hope this is going to help you out.

On the pi sd card you need to put your roms in their correct folders at /home/pi/RetroPie/roms

@edmaul69

Yeah I did a bit of reading mate. I'm a noob with all this but looks like I'm sorted now.

@bigkurz

For MAME specifically, that setting resides in the mame.ini file. However, I've never been able to successfully locate that file in RetroPie or even discover where it could be put manually if need be. Perhaps someone can shed some light on this, but when located you'll want to look for the autosave option and change the 0 to 1.

RetroArch itself also offers this feature, but it will affect the rest of your emulators as well unless 'Configuration Per-Core' is enabled. The 'Per-Core' option is not to be entered into lightly as it can cause it's own set of problems, so it is generally not advised. Either way, that setting can be found at /opt/retropie/configs/all/retroarch.cfg. You'll want to change both savestate_auto_save = "false" and savestate_auto_load = "false" to "true".

@why Please format your posts when posting logs / configs

I guess the question is then that if I have modified or copied files to locations such as /opt/retropie/emulators/retroarch/shader (which isn't a path that a Samba share can see and is located on the USB HDD not the SD Card) how do I make sure this is all backed up aswell??

I'm probably wrong as I am a Linux moron but I thought that when I followed the instructions here https://github.com/RetroPie/RetroPie-Setup/wiki/Running-ROMs-from-a-USB-drive that it placed a lot of configuration settings on the USB HDD that can't be copied with the Samba share??

For example, I know I have made changes to files such as /etc/emulationstation/es_systems.cfg which I assume are now located on the USB HDD but I cannot see these files through the Samba share. How do I backup files such as this??
