Hidden Wireless Link for all multi-player Famicom Mini titles
Gamewatch in Japan reported that the recently released Famicom mini series of GBA games and the Wireless Link Adapters (included with the latest Pokemon games) work together by using a hidden feature. To make sure we don't spread anything wrong we tested the games today and can confirm it works for all games that are multi-player (Mario, Donkey Kong, Mappy, etc).
To use the wireless adapter use the following trick:
You need to highlight the "2 Player" option on the screen but not press start. Instead you hold down L+R and then select the connection method before starting the game.
mmm... interesante. a ver si a partir de ahora todos los juegos empiezan a tener este "fallito". porque anda que que el wireless sólo tire con los pokemon...
