Modding Hori Real Arcade Pro SA

Hello! First post here on Shoryuken!

So, let’s begin! I would like to mod me Hori RAP-SA (PS3) so I can use it on the 360 as well. Also, if possible (but this is the less important of the two) too work on the Wii as well. If anyone would know how to do this and/or where to buy the parts in order to do so, I would much appreciate that.

Any help into this matter would be great! Thanks alot guys!
