Can a Ultimate Mortal Kombat 3 PCB be turned back into a Mortal Kombat 3 PCB?

[Red]

I got an Ultimate Mortal Kombat 3 PCB on the cheap, but what I really want is a regular Mortal Kombat 3 PCB?

Is it as simple as switching out some ROMS?  How much would this cost?  Is it an easy  Do-It-Yourself job for a noob?

Any help would be appreciated.  Thanks.

you need the data roms and the "key rom"  Im sure steph at www.hobbyroms.com can burn you most if not all of what you need.
