d) seems to be the only likely problem.
possible mistakes i might have made include..
-When I open R4Didl to patch ysmenu.nds it comes up with a message saying it's not recognizable and allows me to choose from a list of programs to open it. I've tried winrar but it doesn't work.
So i just patched it with the Dldi tool(the link before it) and followed all the steps to 7 and placed the R4dldi file( which wasn't openable) in the ysmenu dstt directory i made and run ttextract and get the r4patch.dat along with the other files.
-I deleted literal=literals jap instead and then removed the colon.
everything else i did seem right.
