No Enemy for FF4 After Years Pal

[Patedj]

I decided to simply nop the callers bl and what happens is the avatar disappears. I've got the graphics' address.

edit:
This is the map's function

80069214:  48001FB1   bl   0x8006b1c4 nopping this will stop directions (but still allow the map to appear).

80069234:  4800A6E1   bl   0x80073914 nopping this will stop the map from appearing and any directions to be noticed.

Further on

|  |  |  |  |  |  |  |  80067154:  4BFAD959   bl   0x80014aac nopping this will stop the character from looking right.

80073B8C:  4BFA1E2D   bl   0x800159b8 nopping this will stop full screening the game

80073B90:  4BFA579D   bl   0x8001932c nopping this will default screening


|  |  |  |  |  |  80069238:  48000120   b   0x80069358 nopping this will execute "sight" (this will automatically take you into the menu section and show you the whole map) neat! I'll do a button activation for this!

[Patedj]

Sight(map) On/Off
281FB3DA 00000C00
04069238 60000000
CC000000 00000000
04069238 48000120
E0000000 80008000
It'll bring you to the menu. Exit the menu and you'll see the map instead of your avatar.
Button condition can be changed to whatever you like. It's now set as a+b.

[Patedj]

I decided that my search wasn't good enough so I did another search. This time when I poke it it equips the chocobo and the song and all (after I re-enter the map) Yay!.

Code to have chocobo on maps. [spoiler]I'm still working on having no monsters in dungeons.[/spoiler]
281FB3DA 00000C00
0406CC24 38000001
CC000000 00000000
0406CC24 38000000

v2. Works better. Every time you exit a town/dungeon/etc. you will have chocobo equipped.
281FB3DA 00000C00
045442A8 00000001
CC000000 00000000
045442A8 00000000
E0000000 80008000

these codes don't seem to work all the time

I'm starting to think that this is not the chocobo's address again and more the map function.

[Patedj]

here's all frames

[Patedj]

I made a log of the initial break (start to end function) but unfortunately, it loops on one of the addresses for ever. I left it run all night and it repeated the line over and over....

[Patedj]

Woh!! I don't know how I did it but there's a way to have the flying ship equipped after exiting a town.

either this
8006BDBC:  2C000006   cmpwi   r0,6
8006BDC0:  41820038   beq-   0x8006bdf8

or this

8006BE50:  546307FF   rlwinm.   r3,r3,0,31,31
8006BE54:  41820324   beq-   0x8006c178
it's this one.

Flying ship at exit
281FB3DA 00000C00
0406BDAC 38000001
0406BDB8 38000006
0406BE54 60000000

0406BDB8 38000000
0406BE54 41820324
E0000000 80008000
Do not re-embark

[Patedj]

I was able to do a log from the read to the end of the function, with and without the chocobo equipped.

[Patedj]

8006C224:  90760F08   stw   r3,3848(r22)   r3 = 000014B5   r22 = 805428E0   [805437E8] = 000014B5
vs
8006C224:  90760F08   stw   r3,3848(r22)   r3 = 000003E8   r22 = 805428E0   [805437E8] = 000014B5
Allows for the avatar to enter towns and such. No effect on the chocobo.

[Patedj]

beginning logs for the blr, it crashed for both.

[Patedj]

8006B628:  807F0F00   lwz   r3,3840(r31)   r3 = 804D8060   r31 = 805428E0   [805437E0] = 00000004
or this one. They offer different music.
8006B68C:  801F0E90   lwz   r0,3728(r31)   r0 = 00000000   r31 = 805428E0   [80543770] = 00000000
This is the music selector. Let's test it out.

I'm thinking of doing this to it but it crashes...

I really am getting down on not being able to do a music roller...
anyways.
you can simply choose your favorite song and stick to it if you'd like

0406B628 38600004
0=normal
1=Flying ship
2=Whale
3=Flying ship
4=chocobo
+=same things again

0406B68C 3800000x
0=normal map exploration
1=moon walk
2=underground walk
3=ceremonial

[Patedj]

This stops the music from changing between towns/map/fights no it doesn't..

You need a code to walk on grass? o.O

[Patedj]

Your tripping! [spoiler]instead of only seeing the head walk when you enter a forest you see the whole body as if it was walking on soil. So it looks like you are walking on grass[/spoiler]
