I figured it out. The prboom.cfg file is now located inside the saves/prboom/DOOM2 directory. I deleted it and it restored the default configs.

Hello everyone.

I screwed up while configuring my controls in PrBoom for Doom 2. Now I can't enter the game, because I can't confirm the menus.

It only affects Doom 2, not Ultimate Doom.

I tried finding prboom.cfg but I can't find it anywhere, I'm using SFTP (root) to connect.

I'm using the latest stable Recalbox. What should I do?
