yes some cartridges use GB/GBC infrared for linking,like these games：
Bomberman MAX Blue Champion
Bomberman MAX Red Challenger
Harry Potter & the Chamber of Secrets
Mary-Kate and Ashley: Pocket Planner
Mission Impossible (thanks SparTonberry)
Super Mario Bros DX (combine your high score table with a friend's)
Pokemon Gold/Silver/Crystal (get mystery gifts)
Pokemon TCG (thanks Nionel)
Robopon (technically doesn't - it has its own infrared sensor built into the cart)
Xena: Warrior Princess (supposedly, but I can't find more details online)
so the VBA-M are plan to support?
