Need help with GBA codetypes

[Demonic722]

Raw format:

Easier Super Combos[See Notes]
0802020E 2001

Easier Raging Demon[See Notes]
0802020E 2001
0801F016 E003

I guess this would be Codebreaker format since VBA should accept it:

Easier Super Combos [See Notes]
8802020E 2001

Easier Raging Demon [See Notes]
8802020E 2001
8801F016 E003

Thanks Demonic722

so GBA AR v3 use same x2 offset method as AR Max does

[Demonic722]

No problem and yeah, unfortunately.

[lee4]

for anyone is curiosity if rom hack code work on legit codebreaker, it doesn't work.

for VBA the RAW or patch rom will work

Does anyone how to write subroutine pointer for CBA?

[nolberto82]

Do you mean a custom routine?

[lee4]

Do you mean a custom routine?

I think so

[nolberto82]

You need to find a hook in IRAM and branch to WRAM. Then check that the pointer address is not zero.

Example:

LDR R5,=0X30001D8 //Pointer address
LDR R4,[R5]       //load address from pointer
CMP R4,#0         //make sure is not 0
BEQ END           //if 0 skip 

ADD R4,#0X50      //add offset to address
MOV R3,#0
STR R3,[R4]

I need help convert your gba street fighter alpha 3 code

Easier Super Combos
0802020E 2001

pointer 1
02004434 08000000
offset
2020E

pointer 1 the offset is too big for custom routine

I found pointer 2

pointer 2
0201C880 08011A00
offset
E80E

I don't know how to actual write a custom routine for codebreaker gba

[Helder]

You will need to change that value so it goes to your custom routine in ram then copy that last instruction you altered so it gets executed. Then use push on the registers you want to use and after the instructions have done it's job pop the original register values back and jump back to where you set your routine entry.

Like I said in my previous post I dont know actual write a custom routine

I looking for anyone do actual code or dummy code for me

[Helder]

If Nolberto doesn't post one I can have a look for you and post the dummy code.

[lee4]

If Nolberto doesn't post one I can have a look for you and post the dummy code.

Please do

[Helder]

I haven't forgotten about you Lee, just a little short on time these last couple days. Also be warned that the code will be around 20 or so lines of code but it will work and I will explain how everything is set up so you can make changes as you see fit.

[lee4]

sure,

I'm not worried about how many lines.

Thanks for helping me out.
