he links don't work can u help?

What card are you using?

The links work for me. Try copying and pasting the link instead of clicking directly on it.

If it is the R4 original from www.r4ds.comThen update to YSmenu, It will play all them games unpatched, although mario&luigi BIS will have to be the (U) version onlyYsmenu for R4DShttp://www.mediafire.com/download.php?x1ogglxf3mtIf its not an R4 original then down't use thisTopichttps://www.romulation.org/forum/index.php?topic=22731.msg412275#msg412275
