Hi guys!
Can the GBA SP play LSDJ at the same time using the link cable?

The link port works the same on GBA SP as on any other Gameboy. You can use it to sync etc... Just make sure your link cable has the smaller plug on one or both ends (as needed). The bigger plug is used on DMGs and the smaller plug is used on Gameboy Pocket, Color and Advance.
