Your choice of program and methods for making a fan game is up to you, and lots of people will play your game reguardless. The best of luck to you whichever route you choose.
Using the original ROM has more going for it than just "It has all the graphics already there".
*It has all the sound and music already there too.
*It has the same game engine everyone knows and loves
*It has the same FEEL while playing the game, that no RPG maker has yet to mimic
Other +'s for using TF over the others
*People will play the game using an emulator, making your game playable on a MUCH wider spread of computers and OS types, not including emulators for XBox, etc...
*People can play your game on their SNES's if they wish.
I'm sure there are LOADS of +'s for the other options as well, I'm just slightly biased, as every RPGMaker program I've ever played a game from felt nothing like the original, the timing was off, the music wasn't as good, the game physics in general were just off or unrecreatable, the list just went on and on...
If you plan on making a really different type of game, then in that case surely use one of those types of programs.
