If this issue only affects a certain game, which game is it?

Big Bang Mini

Expected behaviour

Game boots into starting menu

Actual behaviour

The developers logo appears followed by a short sound clip and then proceeds to create a new save file. After that it's just a black screen.

Steps to reproduce

1. Launch game
2. Wait
3. Blackscreen

Other notes

I have already tried changing the clock speed to NTR and switch to DS Mode.

Try holding L after pressing A/START to launch the game.

It works now, I keep forgetting that holding L was a thing :P
