I’ll give my 2 cents as I just got my HRAP EX today, which is essentially the HRAP3 but for 360.
I can tell you that everything was working perfectly out of box. In fact, the first place I plugged it in was my laptop. Vista found it right away and it registered as a Real Arcade Pro stick. I tested out the buttons and loade up MAME with Marvel Vs Capcom.
Moves and combos came out pretty flawlessly. Simultaneous button presses registered perfectly. Then on to the 360 with SFHD, and once again, control functions perfectly.
As this is my first serious stick, I’m very satisfied. My actual first stick was an X-Arcade tankstick, and thank goodness I read about it here to find that stick is horrible. Good thing I took the advice to return it and look into a better stick. The difference was remarkable.
Overall, the joystick functions great. The buttons work nicely, but I think they could be better, which is why people suggest Sanwa buttons. I plan to get serious with figthing games again so I’m gonna get new buttons. And I’ve already opened it up to see how simple it was to swap the buttons. If you know how to unscrew screws and unsnap buttons and handle disconnects (pull connection out, push connection back in) then it’s a breeze.
If you check other threads about the HRAP3 and HRAP EX you’ll find some pretty good reviews.
Basically, I’m pretty sure the HRAP3 will function the same way. Many reviews suggest that it also can plug n play for MAME. I’m so happy with this stick, I’m ordering another HRAP EX and 2 more HRAP3 (I have 360 and ps3) for friendly competitions.
And may I suggest you compare the prices with Amazon:
Although Amazon is $99, rather than the $89 at arcadeshock.com, AS charged tax and shipping for me which came out to be $250 for two sticks. Amazon didn’t charge either so my total was only $200.
Hope some of this info helped. Good luck!
