It's 'Okay'
Works with most Emulators, and if it doesn't you can usually get around it using a keyboard emulator such as joy2key. Not the best thing ever though it does not work with M.U.G.E.N. (without keyboard emulation) or my copies of Guilty Gear XX and Isuka. Which was the main reason I got it. Also there doesn't seem to be any sort of tech support for this device. Oh well, like I said it's 'Okay'.

Amazing Site & Product
The registering/ordering process was easy and fast, sporting various shipping methods with full explanation! Good online follow-up!
The product worked even without installing the drivers, but to get all the features you need to install 'em. I didn't use the included floppy because I downloaded the drivers from the manufacture's site.
Works like a charm!!! Windows XP SP3.
Thanks Play-Asia!

GOOD ITEM
I got this stuff and i say one word: GREAT.
I search a long time for this, so thanks.

Super dual box pro
this did work well for about a year, but then one of my ps2 controllers broke, and when I got a new one and tried it, it wouldn't work. in config/calibrate all the buttons were flashing randomly. I haven't tried other controllers ever since. I'm afraid this device might have caused that other controller to break. still works with my oldest ps2 controller and dancepad tough...

extremely good
it worked perfectly for my fighting stick when my previous adapter couldnt detect it.
good drivers with powerful features.
if mine is ever spoilt/lost. ill buy THIS again
