Animal Crossing City Folk Search/Teleport

I know this isn't really "Handheld hacking" but there isnt an amateur coding section in Console Hacking

I'll probably have this finished by tomorrow, I've been busy and stuff

Anyway, here's what I have so far

Code:

item slots: 25 acres 6400 slots 5x5 acres 16x16 per acre coordinates: x and y the part we're using starts at (?) and goes up to (?)+ 4F or (?)+9E (anyone care to help me out here?) formulation: *set two registers to the coordinate value in the top left item slot (X and Y) *search the map for an item, adding to a counter(A) for each slot searched *once the item is found...use the counter for the following *divide (A) by 256 to get acres, remainder=X quotient=Y *add to coordinates *divide (A) by 5 to get rows and columns, remainder=X quotient=Y *add to coordinates *finally, divide (A) by 16 to get individual item slots, remainder=X quotient=Y *add to coordinates to get final coordinates * ? *profit! (I actually understand everything, I just don't know how the coordinates are structured, I probably made mistakes here cause I'm half asleep, but I know how it works...)

pretty hard doing all of this without a USBGecko or any way to view the game's code...but I just kinda guessed all of it, so sorry if I'm wrong about anything

oh and I forgot this game uses the z coordinate...would that affect anything? for example if you teleport from a lower area to a higher area, will you get stuck underground?

Here, I made the formulation easier to understand..I'll edit this post with the code once i've made it

Code:

@sets a counter to 0 @searches the map, adding to the counter for each slot @once an item is found, @divide by 256 to determine which acre it is in @quotient is acre (A), remainder is the slot in that acre(B) @divide (A) by 5 to determine which acre row/column that acre is in @quotient is Y acre row (the rows going left to right), remainder is X acre row (rows going up and down), multiply by 32 and add to x/y coords @divide (B) by 16 to determine which slot row it is in @quotient is Y slot row, remainder is X slot row, multiply by 2 and add to coords

Code:

li r5,0 //set a counter to 0 lis r14, 0x90E8 ori r14,r14,0xF052 // r14 holds slot before first mapslot 90E8F052 addi r17,r14,0x3202 // r17 holds 90E92254 maploop: lhzu r27,2(r14) //load the item stored in each slot cmpwi r27,0x57 //check if that item is a weed blt notreplace cmpwi r27,0x5A ble Move notreplace: //if not, add to the counter, and search the next slot addi r5,r5,0x1 cmpw r14,r17 //until we reach the last slot of the map ble maploop blr Move: li r17,0x11 //set r17 to the value of the top left corner's coordinates? mr r14,r17 //set r14 to this value too (so now we have x and y) andi. r9,r5,0xFF //get the slot number the item is on for the remainder srwi r5,r5,0x8 // and the acre we are in, for the quotient li r30,0 div: //i got lazy and used this stupid divide routine,even thought there is a divide instruction in PPC...once i get this code working ill change it cmpwi r5,0x5 //r5 will hold remainder, which is the acre row blt Next subi r5,r5,0x5 addi r30,r30,0x1 //r30 will hold acre column b div Next: slwi r30,r30,0x5 //multiply by 32 but im not sure how the coordinates are structured on this game add r14,r14,r30 //add to y coordinates slwi r5,r5,0x5 add r17,r17,r5 //add to x coordinates andi. r5,r9,0xF //get the remainder, which will be the row slot srwi r9,r9,0x4 //quotient, which is the column slot slwi r5,r5,0x1 //multiply by 2 add r17,r17,r5 //add to x coordinate slwi r9,r9,0x1 add r14,r14,r9 //add to y coordinate lis r30,0x80E6 stbu r17,0x38D7(r30) //store x coordinate in 80E638D7 stb r14,0x8(r30) //store y coordinate in 80E638DB blr

I just used the Real-Time World Edit source to come up with this, and I'm guessing the address where the X and Y values are stored is "read only" because I can't write to it....So I guess I'll just keep this here, until I get it to work

I found where the x coordinate is stored, but I can't seem to make sense of it (I know I'm trying too hard >_>)

I had to make a hacky routine to actually see the x coordinate though

In the top left corner, it would probably actually be read as 03448010, not 80100344

and in the top right corner, it would probably be read as 3F45F508, not F5083F45
but thats just my guess.

I know it's the x coordinate, cause when i use my routine to store it on my text, it changes in real time if i move left or right, and doesnt change if i stand still. but why it changes the way it does, i have no idea.

:(-sigh- i wish i just got a USBGecko when I still could have
XD

Okay, I have determined how the coordinates are structured, and I will begin making my search/teleport code :D

turns out my viewing routine was wrong. I fixed it.

The x coordinate in the middle of the very left slot is 44040000
with each slot it increases by 8
so, like 4404, 440C, 4414, 441C

the last 4 digits dont really matter

Okay, NOW I have the coordinates figured out. It's pretty stupid. I guess Nintendo was drunk when structuring them. So anyway

Start at 4400 at the very left, end at 4540 at very right (or very top and very bottom for y)
in the first acre, for each slot the coordinates increase by 8
for the next few acres, up until you reach 4500+ they increase by 4 for each slot
after that, they increase by 2

What the heck!? This makes everything so much harder XD
No wonder why Virus didn't use the actual coordinates in RTWE
I'll try making real-time world edit using the actual coordinates, and if I can do that, I'll try making my search teleport code.
Otherwise I'll have to give up.

....please message me about this when i'm on later ;)

Sure ^_^

By the way, here it is....the actual real-time world edit using coordinates (activator c+down)

Code:

I know it's huge, but it works, and it took me forever to think of the math to make it XD (I was about to give up too >_>)
I'll show you the source when you get my message.
I'm going to bed right now, my brain hurts...
