Surprise Homebrew Bonus!

I'm happy to announce that in co-operation with Ken Siders, I am providing a very special bonus item to everyone who orders the Atari 5200 Ultimate SD Cartridge.

Everyone who orders will receive an authorized digital edition of the awesome 5200 homebrew Beef Drop!

Beef Drop is Ken's original 5200 homebrew of the arcade favorite Burgertime!

Even if you are a hard core collector and already own the full version of fantastic homebrew, you can now play your fully licensed digital edition on your Ultimate SD cartridge, or even in an emulator.

PLUS New Atari 5200 Conversions!

In the past few years, dedicated 5200 enthusiests including myself have ported many new games to the 5200 from the Atari 8-bit computer line. Because of these efforts, the available software library for the 5200 has more than doubled since 2005!

To celebrate the release of the new Ultimate SD cartridge, I have ported three new Atari 8-bit games to the 5200!

These are included as "unofficial bonuses" and will be announced in the Ultimate SD 5200 Forum, where you will be able to download them for use on your Ultimate SD cartridge!

You will also find links there to download home brews and 5200 conversions done by others, adding even more games to your 5200 library.
