GBA Emulator to physical GameCube?

The misses and I are loving our retro phase and she's really into replaying Harvest Moon: Another Wonderful Life on our physical GameCube. This is all great and good, but she's always wanted to visit the blocked area up the hill that you NEED to connect a GBA that's playing Harvest Moon: More Friends of Mineral Town to access the area.

Anyways I have some knowledge of emulating and if I can emulate the GBA game, would it be possible to connect my PC or other modern devices to the GameCube to use the GBA Link in order for her to access this area???

-Can I use a GBA Link Cable with an emulated GBA on modern devices to link to a GameCube?
