GameBoy Color EM10 Choke Repair
One of these days, my old GameBoy Color suddenly stopped working, I notice that EM10 circuit is broken.
I ask for help in subbreddit r/AskElectronics (opens in a new tab) and according to the schematic EM10 circuit is a general choke (opens in a new tab) (ACM4532-801-2P).

The battery pack negative it’s connected to the power connector ground, which is then routed to the choke. So if the choke is broken the GBC won’t work.
I short battery negative with board ground (don’t judge my welding skills 😅)
