EDIT: Nevermind, you're right, half-word code is better by a measly 2 bytes lol.

I bet that someday, Skawo and MeroMero will be able to make a rideable Yoshi in NSMB :')

Posted by skawo Podoboo graphics flip on way down  My +1's, take them, take all of them. Posted by KingYoshi A rideable Yoshi in NSMB How to answer this in the most polite way possible? Hmm… Posted by MeroMero I want to switch focus now and put on hold NSMB for a while, and go back to Pokémon Mind Crystal to polish all the ASM Hacks I did in it. Please understand. |

There's also some documentation on the Podoboo here I might as well post:
spriteaddress + 6A = u16 X Pos
spriteaddress + 6C = u16 Y Pos
spriteaddress + D4 = u32 Velocity (only uses the bottom 24 bits)
spriteaddress + 47A = u16 Jump height
spriteaddress + 488 = u16 add to tail bit 1 ncg id
spriteaddress + 48A = u16 add to tail bit 2 ncg id
spriteaddress + 48C = u16 add to tail bit 3 ncg id
spriteaddress + 498 = u16 add to tail bit 1 ???
spriteaddress + 49A = u16 add to tail bit 2 ???
spriteaddress + 49C = u16 add to tail bit 3 ???
spriteaddress + 4B8 = u16 Tail bit 1 NCG ID
spriteaddress + 4BA = u16 Tail bit 2 NCG ID
spriteaddress + 4BC = u16 Tail bit 3 NCG ID
spriteaddress + 4C8 = u16 IsPodobooUnderLava
spriteaddress + 4CA = u16 LavaTimer (jumps out if <=1)
spriteaddress + 4CC = u16 something about drawing the tail
spriteaddress + 4CE = u16 head pos wiggle offset X
spriteaddress + 4D0 = u16 head pos wiggle offset Y
spriteaddress + 4D6 = u8 HeadRotation (2 = upside down, 0 = regular)

Would you be able to make something so that you can choose the time it takes for the fireball to come out of the lava again after it went back into the level, a la NSMBWii?

It would be a nice feature, yes. (Don't know if I'm the only one to think that tho
 ).

Timed Podoboos:
repl_021480D0_ov_30:
STMFD SP!, {R1,LR}
LDR R1, [R4, #8]
LSR R1,R1,#0
AND R1, R1, #0xFF
CMP R1, #0
STREQH R0,[R3,#0xCA]
LDMEQFD SP!, {R1,PC}
CMP R1, #1
MOVGE R0,#0x5
STREQH R0,[R3,#0xCA]
LDMEQFD SP!, {R1,PC}
MUL R0, R1, R0
STRH R0, [R3,#0xCA]
LDMFD SP!, {R1,PC} Uses nybbles 11 and 12 (the two last ones). If 0, it'll use the timer the game calculates (i.e a random one). If not, it'll do 5 ticks * nybble. |

Well, the second thing's quite nice, though I don't really see that ever happening.
...but I've already done the "super fast coins" thing in the "Ghost Star Coin" patch, and it works just like you've shown. So, uh... :l Crude Common Enemy Retexture Code: hook_02006984_main:
STMFD SP!, {R0,R1,R2,LR}
LDR R1, =0x212EE94
MOV R2, #0x600
ADD R2, #0xA9
STRH R2, [R1]
LDR R1, =0x212EED4
MOV R2, #0x600
ADD R2, #0x6D
STRH R2, [R1]
BL .AlternateGoomba
BL .AlternateKoopa
LDMFD SP!, {R0,R1,R2,PC}
.AlternateGoomba: #Example of world-based retexture
LDR R0, =0x2088BFC
LDR R0,[R0]
CMP R0,#0x4 #World ID
LDR R1, =0x212EE94
MOVEQ R2, #0x1C #Custom NCG ID - 0x83 here
STREQH R2, [R1]
BX LR
.AlternateKoopa: #Example of level-based retexture
LDR R0, =0x2088BFC
LDR R0,[R0]
CMP R0,#0x5 #World ID
BXNE LR
LDR R0, =0x02085A9C
LDR R0,[R0]
CMP R0,#0x2 #Level ID
BXNE LR
LDREQ R1, =0x212EED4
MOVEQ R2, #0x1C #Custom NCG ID - 0x83 here
STREQH R2, [R1]
BX LR Allows you to hardcode retextures of Koopa Troopas and Goombas based on the World and Level. |

Posted by MeroMero Improved Red Coins: (…) Possible values: _Nybble 4: 0: Fire Flower 1: Mini Mushroom 2: Blue Shell 3: Fire Flower modulo 4 What's the difference between 0 and 3? Also, I assume you'll have to set the values you want in all eight red coin-sprites? |

So, uh... :l Actually look at the timing where the Star Coin disappear, it's even earlier than in you video. Don't scare me like that, I thought I had wasted a few hours just to do a duplicate *faints from shock* Posted by KingYoshi Posted by MeroMero Improved Red Coins: (…) Possible values: _Nybble 4: 0: Fire Flower 1: Mini Mushroom 2: Blue Shell 3: Fire Flower modulo 4 What's the difference between 0 and 3? Also, I assume you'll have to set the values you want in all eight red coin-sprites? Values 0 and 3 are the same, no difference whatsoever. And yes you have to put the values for all 8 red coins. I know, it would have been more intuitive to put the value on the Red Ring, but coding-wise it was simply easier to set the value for the Red Coins instead. |

But what if you don't set the same value for all 8 coins? Does the game only look at the value of the last red coin you take? |

Indeed that's what the game does, you can setup different parameters to throw in a twist.
Don't do that though, this ASM hack was not designed for that purpose. |
