Cannot change back emulator choice per Rom (solved)

[Knuckles78]

@mitu Thank you for your help, I’m taking the time to understand more about the terminal. I watched a few videos, and now what you’re saying to me makes more sense.

@mitu /home/pi/.profile doesn't exist. Is that a file with no extension that I create?
Nevermind. I just found the file. I couldn't see it in the terminal, but PIXEL could see itl

@IanDaemon Files and directories with a leading . in their names are hidden in Linux. To list them with ls, use the -a ("all") option. You can combine multiple options after one -, so -l -a becomes -la (or -al, as the order doesn't matter for options without further parameters).

ls -la

edit: You could create another alias to list hidden files, e.g. lla:

alias lla='ls -la'

Cool! Thanks. In PIXEL/LXDE I have "show hidden files/folders" enabled as my default.

@jackyracer You are a lifesaver, just had this issue and found this, Thankyou

Solution worked (remove the corrupted file) but since I have way too many mame games with different emulators set, this isn't really a file I wanted to "start over" on. Similar to what @jackyracer already said, just wanted to remind and confirm that in my case I copied the bad file to my computer, still opened (thank goodness), copied and pasted the cfg text from the old file to a newly made emulators.cfg file, and moved the new file back over in the same place. All fixed, but most importantly, no damage done.
