It doesn't matter what kind of response box you use, so long as it is
compatible with your scanner and whatever program you use to present
your stimuli (e.g., Matlab, EPrime, etc.). Typically you will record
response times in your presentation program, and then do some offline
manipulation to get the times for each event type you are interested
in, and then pass these times to FSL. "Event type" could refer to an
experimental condition or a type of behavioral response within an
experimental condition. This is all calculated outside of FSL, with
FSL just seeing the list of times for each event.
There is some more about entering event times here, under "EVs":
