I can’t find any details on power requirements for any arcade sticks, but I don’t think it’s an issue with a 1000ma PSU. You could use an externally powered USB hub to see if it really is a power problem.

You say it worked with the previous RetroPie image, so that leads me to think that this is a driver problem. I’ll need to do a bit more digging to try and find out whats going on.

This page has a lot of information on peripherals, it also includes information on the power usage between different models of the Raspberry Pi and lists all the peripherals that are known to work.

May I suggest updating your RPi:

There are two steps to upgrading. First, run sudo apt-get update in order to synchronise the database of available software packages and the versions available. Next, run sudo apt-get upgrade which will cause any packages with newer versions available to be updated.
