If you know the total, do you need to create hits and misses separately? Isn't misses=n-hits?

How about...
*make data like yours
clear
set obs 500
gen participant = _n
forvalues i=1/10 {
gen r`i' = runiform() < 0.5
gen w`i' = runiform() < 0.5
}
*create hit and miss totals
egen rhit = rowtotal(r*)
egen whit = rowtotal(w*)
gen rmiss = 10-rhit
gen wmiss = 10-whit
