I mainly want to be able to finally play Final Fantasy III (translation patched) without emulation. Will I have to get the Famicom version of the Everdrive with the Famicom to NES converter, or can I just play Famicom ROMs on an NES version Everdrive?
Also, is there any way to play the Japanese version of Castlevania III on an Everdrive, to experience the upgraded music? (the J version used the Famicom Disk System) Is this what the features list as "expansion sound" (where you have to modify an NES to do it)? If so, how do I go about modifying my NES to support CVIII's expansion music?
