[GoogleCodeExporter]

What steps will reproduce the problem?
1. Attempt to load "Ms. Pac-Man (U) (Tengen).nes".
2. Error message
3. Shake fist in anger, cursing emulator developer name(s)

What is the expected output? What do you see instead?
Expected output is the ability to play the superior port of Ms. Pac-Man in the 
superior NES emulator.
Instead I get the following error message:
---------------------------

What version of the product are you using? On what operating system?

Remix III (64-bit)

Please provide any additional information below.
Namco's official port of Ms. Pac-Man is god awful. I want to play the better 
port!

According to http://kevtris.org/mappers/tengen/800003.html this board is just 
NROM. Adding it to the list of NROM boards seems to work.
