Location | Notes | RNG 1 | RNG 2 | RNG 3 |
|---|---|---|---|---|
Sitting On Yep | 20 total cursor movements (with A and start for confirming selections. | 5E | D4 | 0000 |
Out of Bed | Watch the cut scene for funzies | E7 | A5 | 0000 |
A takes it | Left, up-left into room, down-left slightly to go around desk, L to take present quickly. | 8D | 48 | 0000 |
Leave house (Black screen) | Equip the bat (must go quick or the RNG messes up. If Paula moves down then right, you are good. Out of room, the left down stairs, slight down-right to make it around the table, then right out of the house | 05 | 50 | 0000 |
"Hey, A" | Down-left slighty, then down to grass line at fence-line. The game lags here very slightly so use that as a cue to then turn down-left. Go all the way down, the left against cliff. Up-left around. At traveling salesman area, up-left over diagonal flower line, then up when you are in line with the upper-most pink flower in that little line. RNG 3 is not active here so specific movement when NPC's are not loaded is not important. Note that Pokey's movement is scripted so it doesn't matter how long he stays on screen or when you talk to him. | D3 | EB | 0000 |
"Welcome home, A" | When you're going through the salesman area again, bump against the tree to force Ness into that X coordinate so that the RNG is guaranteed. Turn right at the bottom flower. Then wrap around and diagonal-up into Ness's house (the opposite of what you did coming out). | 83 | 95 | 0000 |
"L-L-Listen!" | Left, down the stairs (Tracy should go up, then left). Down-right (you can use the second pattern down from the table on the floor as a reference of when to turn right. Hold right, then up-right a little underneath the dog to put you underneath the couch, then right more until Pokey emerges | B7 | F7 | 00AA |
Dressed in Room | Left and talk to mom. She should move up and be in your horizontal line. | FC | FA | 00CD |
Leave House | Left to downstairs. Down-right a little to the same pattern point as before. Up-right to talk to pokey. Right to door, then left and up to phone. (Mom should be in the middle of her movement when you use the phone. Just go quick and you'll catch it at the right time). Down , then right and out. The RNG value is not super important here as it can fluctuate based on wrong movement. You're expecting ideally one dog to the southwest, but several other spawns can result in the same ending RNG if you follow the exact same actions. A snake and a crow, for example, will fix itself if you follow the same actions. | 9E | 6F | 0154 |

Ness gained 685 Exp! | Bx3, use bottom bomb, Down, PSI, A or L 45 times, B, up, use Bomb normally. My technique for mashing 45 times is the following: with right thumb on A and left index on L, start counting from 1 on A, then start alternating A to L. count up on each A press. On the A press when you count 23, you're done. | 23 | A2 | 0841 |

First round: Defend Second round: Up Left Run Third round: B ATM card Fourth round: AB defend Make sure to mash fast through the last damage done to your death. Not doing so can make the RNG tick forward again. | B9 | F4 | 08E7 |

Inside Police Station | Walk right, Down-right through tree, down to guide against right side, Down+left at curb, left at curb, Up+left in. (Make sure you hit those walk out and hit those curbs. Not doing so makes RNG inconsistent. Don't ask me why). | D3 | 1D | 099A |
