Alex the Allegator 4  
Strange how it's supposed to play like a Game Boy game but ends up feeling new and fresh, you know? Alex 4 is lovable--down to the last pixel.

Empire Allegro

Icy Tower  
Icy Tower is feature-rich, stylistic, and polished. It's pretty good, but don't let the hype cloud your thoughts.

KiGB  
KiGB is perhaps the most complete piece of software I've ever had the privelege to download. With the potential of thousands of blissful play hours, it appeals to the gamer part of me. Yet, with the seemingly flawless emulation (you will think that Mr. Liu somehow carbon-copied a Game Boy), it appeals to the programmer part of me. I hope to see it flourish.
