RNG 1: 1 byte hex value at 0x7E0024

RNG 2: 1 byte hex value at 0x7E0026

RNG 3: 2 byte hex value at 0x7E4A7A

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
