Since the first version of Visual Boy Advance which lacked some major features (such as an interface), this Gameboy Advance emulator has progressed greatly. I found compatibility to be quite good and many games were playable. Actually I didn’t have any problems with every game I tried, though I must admit I didn’t test a whole lot of games.
The games ran at full speed (with sound) on my Celeron 900 Mhz., so if you have a similar or faster PC you shouldn’t have any problem either. A Pentium III 500 Mhz. is the absolute minimum requirement to play games. The Gameboy Advance is a 32-bit machine so emulating it requires more CPU power.
ZIP Support

Visual Boy Advance has ZIP support. This means you don’t need to unzip your ROMs before playing. Just select the ZIP file and Visual Boy Advance will automatically load the ROM from it.

Gameboy Emulation
Visual Boy Advance can just like a real Gameboy Advance also play original Gameboy (Color) games. So there is no need to get a seperate emulator. Because of this the author has stopped development of his “normal” Gameboy emulator Visual Boy.

About Nintendo DS emulation
Unfortunately emulation of the Nintendo DS is still at an early stage. No emulator exists yet which can play most games properly. This means the current focus of emulator authors is to make their emulators more accurate, which in turn means that optimization has less priority. Due to this, even if a game can be played, it might run extremely slow – even on the fastest PCs available today.
