Advance Game Port
Datel's version of the Game Boy Player, released in 2003. This dongle would connect to memory card slot B and would be booted up with the included boot disc. Some models had code generators for built in cheat devices. The advantage was that no removal of plates on the bottom, nor tools, were needed to install it. Unlike the Game Boy Player, however, there are a few problems with the audio and video framerate and was not 100% compatible with GBA games.
It is compatible with Wii, but it requires use of a Freeloader (or Action Replay with Freeloading function built in). First you activate the Freeloader/AR as you would for playing an import, then put in the AGP disc, then remove the Action Replay memory card if you're using one, and insert the AGP into the memory card slot, and finally plug in a GBA game. If this does not work you will may need to tamper with the pin connectors, as some unlicensed memory port accessories need slight modification to run on Wii.
