Here is very good comparision between gameboys.
Sure, these games aren't new, but they're newly produced, making it another example of how Game Boy games are still being made today. While only a select few new Game Boy creations actually manage to find a publisher, there's a wealth of projects out there that work natively on the Game Boy.
