Hi, I just bought a nintendo 64. it came with the controller pak. So i decided to buy a rumble pak. I then found out this thing (Hyper Pak Plus). It says it has both controller pak and rumble pak so it saves you the hassle to change them. It says it has 4 times memory than the controller pak and 2 rumble settings. I can buy rumble pak about 10 USD (shipped) and Hyper Pak Plus about 20 USD (shipped) Here are the questions: Is it worth the difference? Is there a list i can find the games which need controller pak to save? Do i really need 4 times the space? (I heard some games like mario kart needs a lot of space when saving ghost replay) How is the rumble compared to the original rumble pak?
