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 :)
