Hi, I'm using the R4iSDHC Original (http://www.r4isdhc.com/r4-download/) with the latest 1.17b firmware. I tried to play the Yugioh 2010 but no luck. I have tried to patch both the US and JP version with both the xdelta and Rudolf's patch but it still doesn't work. It just displayed: "Unable to read data. Please turn off the power and reinsert the game card" Then I heard about Ysmenu and tried it. It got me past the title screen but whenever I tried to play the story mode or start a duel in WC mode I got a black screen. Now I have some questions: - Is my card a R4 clone or a DSTT clone? Has anyone experienced the same problem with the this? Have you found a way to fix it yet? - What do the "extinfo.dat" and "savelib.dat" do? Are they crucial to the YSmenu? Where should I put them? I use the a2h's YSmenu builder and it only ask me to provide the infolib.dat, which I did. Do I just have to put them in the TTmenu folder? ( I put the latest extinfo.dat, savelib.dat and infolib.dat into the TTmenu folder but it still doesn't work) Thanks for your help!
