i was wondering........ if i wanted to hack a n64 rom would it be very complicated? and what programs would i need to do this? and how long would this take? because i have some cool n64 game hack ideas!

for example.........

what about a version of paper mario but with sonic? ( sonic instead of mario ) I would call it paper sonic and swap princess peach with amy rose, swap luigi with tails, swap bowser with eggman, swap kammy koopa with chaos ( chaos is a blue water monster) and many other changes.

any answers?
