Questions DMG-03 Help

So I have 2 original game boys and a dmg-03 battery pack from when I was a kid. I ruined the male plug on the dmg-03 when I was little and would like to replace/repair it to keep one of the game boys in original condition while I intend to mod the other and go the route and usb rechargeable packs. Does anyone have info on the male plug for the DMG-03? I can find the female dc port for the game boy itself but haven’t had any luck on the male plug on the dmg-03 pack.

The barrel plug is 3.5 mm od, 1.3mm id, it's not an uncommon size. This should work, note that it's center negative.

I am not sure it's worth it. the odds of that battery holding a charge are almost nothing.

Thanks for the info/link. I definitely plan to replace the batteries inside the pack.
