This might be the "rarest" 100% we've gotten. Despite owning all the peripherals (and the game) since childhood, we barely knew about the GBA connectivity for the longest time and hadn't dealt with it until recently. Feel free to read the thread if you want a brief read about an obscure game 🙂.
After a long while of on/off trying, we finally true 100%'d Amazing Island! For genuine 100%, you need two GBAs, a GBA link cable and a GCN link cable. Playing through all of the minigames was a fun exercise in discovery, but the GBA tribulations were a completely different story... (1/5)
