everything retroArch broke moving External drive to laptop

[lovemehate]

am scared to reinstall anything as I spent a very very long time setting it up last year. I don't want to lose my filter settings, directories.

is there any simple fix? Can i just reinstall retro-arch without losing all my cores and bios settings?

I tried a fresh install just to test it out, and just trying to get naomi to run is a nightmare (keep getting bios error) even though its in the correct directory.

I dont want to go through and fix 30 odd systems.

any suggestions on something to try to fix this?

Reicastlibretro , nothing happens when right quick, launch with ....(for Naomi and Atomiswave)

I tried opening Retro-arch app outside of launch box, and even when loading core , then game? I get "Error loading core"

I have use the retro-arch to update all shaders, cores whatever else I was able to

I have no idea what to do

If you plug the external drive back in where you initially set all of this up, does it work again?

I'm not that familiar with RetroArch but it stands to reason that moving the external drive to another machine likely changed the expected filepaths you had setup for certain items. It's probably going to be down to ensuring the external drive has the same assigned drive letter on your laptop. Also if RetroArch saved any files to user folders on the previous machine, you'll likely need to make sure those match up and exist on your laptop.

 

::EDIT::

I also just remembered that Launchbox has a bunch of RetroArch stuff integrated now. Features I don't personally use, sorry. I'm used to treating RetroArch like its own thing. Still you might want to look into your file pathing when swapping drives around.
