help with dslite and dsi

i have a ds phat ds lite and dsi
my dsi's L and R buttons stopped working months ago so i just started using my ds lite instead for all those games that required them but now my ds lite's L and R button are getting a bit unresponsive does anyone know how i can fix this spending little to no money
(i don't really have much money at the moment)

(What on earth are you doing to those poor machines?)You could get a screw driver (tri wing if i remember correctly) and poke them out or see for any obstructions.My advice-be more gentle

It'll take money to fix them. Sounds like the shoulder pads are worn out. You can replace them yourself if you can take a game system apart. I built a PSP with no prior knowledge, so it wouldn't be too hard for me to fix those.

ok i did use the R button alot in mario kart racing friends on the bus for at least 2 hours a day that was the first side to go
and then cod multiplayer made me lose the other side :(
