So, I may be a noob but will this still work with SMW hacks?

well after looking at the mmc3 specs, i believe it is able to support adding more prg and chr banks. if i calculated correctly smb3 only uses half of its potential in both catagories. bank switching would allow more room to toy with and its not that difficult to do.
