Good stuff. Much appreciated.

I'm looking to set up Makaron in the next few weeks, so I'm trying to get all the info. I'll need beforehand.
I've got a 3.0GHz HT P4 with 1GB RAM and also a Core 2Duo 2.4GHz with 1GB RAM, both running XP.
What kind of performance will I get with the 3.0GHz HT P4?
What kind of video card do I need? I'm not looking to spend big bucks on a video card, something mid-range.
One more thing, Do any of the Naomi Emulators allow use of a joystick/gamepad on their own or do you have to use a program like XPadder or Joy2Key?
