I had it working just fine after adding a couple of roms and now after a second round of adding roms and bios files, it no longer works. Clicking on it within Steam OS just flashes to a black screen for a sec and then goes back to the OS without opening emulation station.

​

I searched a bit and found someone with a similar problem but the explanation to fix it made no sense as if it was written by someone who didn’t speak english and/or expects everyone to be hackerman rather than a normal human being. Here’s that post: https://www.reddit.com/r/SteamDeck/comments/u689e2/pcsx2_fix_blackscreen_and_close_emulator_after/.

​

Can someone please help by explaining this in English?
