I Need A Very Easy Tutorial for YsMenu for Mac

Hi there i am looking for a tutorial for the mac on getting YsMenu on my R4 original.
I really want to play mario & luigi bowser inside story on my r4 but it freeze and I need the YSMENU.Also if I do get it working will it first boot the normal R4 1.18 firmware before I open the YsMenu? Because I would like to keep my themes for my r4. Thanks and hope someone can help!

You can download an already made one here.https://www.romulation.org/forum/index.php?topic=27617.0

The tools involved in the process of compiling a build of YSMenu are Windows based unfortunately. You'll have to download a pre-compiled copy^.

i downloaded that and then do i download ysmenu.nds off yasu site? i have done that but then when i start it up it works.
I go locate the rom (M&L BIS) click, it loads but then it says:[Rom loading failed]
disk errcode=-82Please reset system.Its getting annoying.
I reinstalled all the r4 1.18 firmware too.I downloaded this one:Ysmenu for R4 Revolution For DShttp://www.mediafire.com/download.php?4jtmzzdmmov

lucky for you im a macintosh user http://www.mediafire.com/?w1judgwdzlj, this should work.
