Really Simple mod, didn't turn out as bright as I hoped. I might replace the LED's with some brighter ones later.

Very cool! I really like the LEDs. Did you manage to save the original oscillator so you could switch between normal speed and overclocked speed? I was going to do that when I overclocked my GBA, but I had to break the original oscillator just to get it off the board. Sometimes it's nice to have the original speed (Tetris ).

Thanks! Unfortunately I couldn't get the mod to work while keeping the original oscillator intact, and ended up breaking it. Oh well. I've got an SP that's overclocked and still has the original oscillator installed along with the faster one, so I don't really care that much.
