I got a kinda beat up NGPC + Sonic Pocket Adventure for $5 today at the swap. I just got home, popped in fresh batteries and tried to turn it on but nothing happened. Just a blinking power light. Does anyone know what this mean and is the system repairable? Or shall I keep it around for parts and tinkering around. I don't mind either way since I got a good game out of it at least that works and I have a NGPC in great condition anyway.
