I have just discovered that my left shoulder button on my DS has ceased to be.

Although a great excuse to buy a new machine it did make me question how many games use the left shoulder button.

I could not think of that many.

 

Daigasso! Band Brothers
Daigasso! Band Brothers DX / Jam with the Band

I don't know of any others.

 

When my R button stopped working, I opened up my DS, cleaned it out a little, and tinkered with the button itself, and it ended up working again for another 9 months or so. Maybe try that? Many, many games use the shoulder buttons, haha.

 

Mario Kart uses the L button but you can always use X instead

 

Thank you kevan.

I lots of very hard blowing later my left should but seems to be okay again.

Like the simplicity of the solution.

I shall continue to find games that uses the left shoulder button, just so I can be prepared for it's likely future return failure.

 

All Pokemon GBA/DS games can use L as A if you set it in the options. You lose the functionality to cycle through your inventory in HGSS, though.
