Kay, I downloaded Yugioh 2010 and put it into my R4, it then state "Unable to read the data" when it's played.. Then I use the DSlazy and replace the arm7.. When I played it, the whole screen went blank (both screen black in color that is).. It can still be play, there's sound and you can even hear the sound of you clicking something.. Just that you can't see a single thing.. Is it the rom's problem? Or do I need to update stuff or anything? Thanks in advance..
