I was planning on building a Mame cab, had my plans and got the roms...then my wife decided to surprise me

She bought me an Arcade Legends machine with ALMOST all the games I REALLY wanted (208 already on the machine). I tried loading a couple of the Roms I had onto the Legends machine with no luck...is there (dare I hope) a patch to add to the rom and make it compatible? I do really like the front end set up...and don't want to hurt her feelings by building a second cab so soon after she was awesome enough to get this one for me...but I'm jonesing to play Gaplus, Scramble, Splatterhouse and a few others that I'd probably buy to own legit copies for the Legends machine if that was an option...
