a5200DS
--------------------------------------------------------------------------------
a5200DS is an Atari VCS 5200 console emulator.
To use this emulator, you must use compatibles rom with a52/bin format. 
You also need the 5200.bin rom bios to use it (there is a built-in open-source
replacement BIOS which will work for many games but doesn't have full compatibilty
so it is still recommended you use 5200.bin). A quick search on atariage website 
will help you about that ;-) Do not ask me about such files, I don't have them. 

Features :
----------
 Most things you should expect from an emulator. 
 Most games run at full speed on a DSi or above.

Missing :
---------
Sound emulation is passable but not great. I wish a good sound engineer who
knows how to program for the DS would come along and magically make it sound 
perfect... but at least all the sounds are available now :)
