SM64 Lock-On technology
(Doesn't need N64DD!)
First, hold the console in your hands, and sing "Smooth Criminal" by Michael Jackson (R.I.P.) once.
then, drop the console on your feet.
THIS WILL HURT, BUT GET OVER IT LIKE A MAN, YOU BABY.
next, play file D and complete the game with 120 Stars.
afterwords, shut down the system, take out SM64, and start yelling at the cartridge for 10 minutes.
no insults or anything, just scream and yell at it.
next, shove Sonic & Knuckles into your N64, and shove SM64 into S&K's Lock-on port.
DO NOT TURN THE CONSOLE ON.
after forcing in the cartridges, shove a Gamecube to GBA cord into the player 2 controller port. (GCN Side in N64, GBA in GBA.)
Next, play Mario and Luigi Superstar Saga until Mario or Luigi learn a Bros. Attack Advance.
Mario and Luigi will jump upwards offscreen after you beat the battle you learned the advance during.
The game will save, go white, and say "Turn off the Game Boy Advance and look at your cartridge!"
Sonic & Knuckles should either be in your Sega Genesis (Assuming you have one), or right by the N64.
SM64 should be in the N64 by itself, with a new port on top of it.
What's it supposed to do? Well, it will be a required component for other cheats you can't normally get without it,
but those cheats are for another day....
Oh, all right, but just one.
Play SNES/Genesis games on N64.
The SM64 lock-on port can support SNES, Genesis, and other N64 game cartridges.
You can use SM64 as a passthrough to play these games, except for N64 cartridges.
Other N64 cartridges are for other SM64 cheats.
To use the passthrough technology, just turn on the N64 with the game of your choice in the SM64 cartridge.
If there is nothing in the slot when you turn it on, it will just play SM64.
Controls?
SNES - A is A, B is B, C down is also B, C right is A, C up is X, C left is Y, R is R, L is L, Z is Select, and Start is Start.
Genesis - A is A, C down is B, C right is C, B is X, C right is Y, C up is Z, R and L do nothing, Start is Start, and Z is Mode, whatever that's supposed to do....
Obviously enough, both the Analog Stick and N64 D-pad control the In-Game D-pad
Now that you know how to use it, enjoy your new 3-in-1 game system, and be on the look out for more bodily-pain-causing cheats!
Have fun!
