Noise Mod Gear
From The Rockman EXE Zone Wiki
Continuing the Wave Command Cards from Mega Man Star force 2, Ryūsei no Rockman 3 introduced Noise Modification Gear (ノイズ改造ギア) to further the usage of real life cards to fully customize your Rockman. They were sold by Capcom during the lifetime of Ryūsei no Rockman 3 with several only being obtainable during in person events in Japan.
Features
Unlike the Wave Command Cards from SF2, Noise Cards (ノイズドカード) specifically add abilities to Rockman directly instead of changing the enemies, obtain items/zenny or convert blank cards into battle cards. Noise Cards are activated in the Rockman Status screen and are entered using the bottom screen with the Noise Card overlayed to show where to press. There are also White Cards (ホワイトカード) which give a preset of 4 cards for use in your folder and Purpose Cards, known as Rezon Cards (レゾンカード) in the japanese version, which add bonuses to Rockman upon Finalizing to Black Ace/Red Joker.
Noise Cards and Purpose Cards are locked in international versions while White Cards are available in the US and EU versions.
