I can't get 4187 - The Idolm@ster: Dearly Stars working on R4. It has compatibility with DSi, but it works just fine with the regular fat DS / DS Lite, I heard. Already tried several things, like YSmenu and arm7 fix and none of them worked properly. R4's regular firmware can't even read the game's title while YSmenu can, but whenever I try to boot it with YSmenu, I get the load rom errcode =-4 message. So, I'm here asking for help. Many thanks, close this thread if necessary.
