Thought I better check mine and I have the same problem

Anyway does anyone have any ideas why so many are not working is it purely a compatibility issue or could it be they need more power? I wondered if it was wired direct to the power boost, would this help or am I wasting my time?
I have ordered one recommended off the wiki but that won't turn up for a few weeks so looks like I'm not going to have my gameboy for my hols unless someone has any ideas???
