A600gs not booting out of "hit any key to continue screen"

[fordprefect]

Hello,

Just got this system in the mail, hooked up everything (got the checkmark mouse), I get the loading screen with a checkmark and the system loading audio, then I get to the screen where it says to hit any button to continue and cannot get past it. I've tried everything, 2 different keyboards (one from my Vampire V4 SA,second one just a generic keyboard I use on various systems),several different mice and trackballs, and the included game controller. Absolutely nothing is getting me past this screen.

Very odd, as I boot them 3 times after flashing to ensure they are booting and working correctly with included pad.

What PSU are you using?
Have you tried other usb ports?

Also using front ports with anything other than a Joystick will not work.
