On 21 January 2012, Balboa scored the inaugural goal in the 2012 Africa Cup of Nations, the game's only as the co-hosts defeated Libya. In the 2015 edition of the tournament, also hosted by his country, he won a penalty after being fouled by Gabon's Lloyd Palun, and converted it to open a 2–0 win which put Equatorial Guinea into the quarter-finals. In the last-eight encounter, against Tunisia, he converted a late penalty to tie the game at 1–1 and eventually take it to extra time, where he scored a free kick to take his country to its first ever semi-final.
