White screen when I tried to load up gyakuten kenji 2 :(

Hi all,I tried to get gyakuten kenji 2 to work.. but Im getting a white screen when I load up :(All I did was this:"Over-Ride DAT's extinfo.dat/infolib.dat/savlib.dat/usrcheat.dat
into the TTMenu folder of either DSTT/YSMenu R4's - Are any of RGF ttmenu folders."All my other old games work fine, except this new gyakuten kenji 2..Appreciate any advice!!P.S. - I seriously googled everywhere but can't seem to find anyone else with the same issue. Had the error = -4 at first but that disappeared after I over-rided the DAT files..
