Pet Project - FFR

For the amount of work you're wanting to do, it's probably best if you wait on this to get completed:

Using that, doing what you're wanting to do would be pretty simple. However, the SNES rom simply can't hold that much data without a ton of workarounds.

Of course, the downfall is the developer has said it will likely be at least another year before it's complete, though he has added rom integration for those that would like to hack the rom in the meantime and add that information into the SDK later.
