I did something really dumb while trying to re-bind my MAME emulator’s config key. It used to be Tab, and while I was trying to re-bind it to one of my gamepad buttons I un-bound the key, and now I have no way of accessing the config settings.
I found this section of the mamedev wiki, which suggests editing the default.cfg file. But I tried to access that file and it appears to be blank when I try to edit it via Putty using:
default.cfg also isn’t in the mame-advmame directory. apparently its location changed with Retropie 3.0:
I must be doing something wrong. Out of all of the keys to accidentally un-bind, I do it to the most important one! How do I fix my very dumb mistake? And where do I even find the default.cfg file that I’m supposed to edit/delete? I’m even willing to completely re-install AdvanceMAME to reset my bindings.

RetroPie Version Used: 3.0
That was actually one of the first things that I tried. But it didn’t reinstall the AdvanceMame emulator- it seems to have just updated it. I’m still having the config bindkey issue. And since RetroPie 3.0 is so new, there aren’t any resources online that point to a solution, yet! I found a mame.cfg file in opt/retropie/emulators/, but it doesn’t contain any keybindings for the MAME config menu that’d normally be accessed using the Tab key.
