Replace the blank CFC2English.ngp file included in this package with a valid
CFC2English.ngp NGPC ROM file.
Run CFC2English.nds and select the CFC2English.ngp ROM file.
Information about CFC2English can be found at http://cfc2english.blogspot.com/
It should also work with the original Japanese-only CFC2 ROM file
(if you rename it CFC2English.ngp).
