MekkaBoy

0.16.0 beta: first public release.

• Four original games, all in beta: City Gates, Critter Crate, Overload and Gearworks.
• Add games you own through the Workshop at workshop.mekkaboy.com (paste a code for Game Boy games, drop in a folder for Advance games). Games you add play without sound unless you record a soundtrack pack.
• Link play for supported games: trade and battle with a party member. Pokémon Emerald multiplayer verified by two players in the live beta.
• Pauses itself for ready checks, queues, summons, trades, duels and flight landings; closes in combat.
