Previously, the service was only accessible via the Wii emulator on Nintendo's new console, but will now arrive on the eShop at some unspecified time in Q2 and feature GameBoyAdvance titles for the first time.
The hardware emulator can use its namesake five cartridge slots to play original games from no less than nine vintage consoles, including the Genesis (Megadrive), NES (Famicom), SNES (Super Famicom) and GameBoys from the original through to the GameBoyAdvance.
