 |
|
Hi there, i'm making a script that modifies bytes, in my aobscan i have an unknown byte "??" that i want to nop.
The problem is when i want to restore that byte, i can't because i don't know the original byte.
Here's my script: (Credit to Rydian for his amazing tutorial about aobs)
| Code: |
[ENABLE]
aobscan(spr, ?? 05 0F 57 C0)
label(_spr)
registersymbol(_spr)
spr:
_spr:
db 90 90
// new aob: 90 90 0F 57 C0
[DISABLE]
_spr:
db <what_goes_here> 05
// new aob: <what_goes_here> 05 0F 57 C0
unregistersymbol(_spr)
|
I thought i would use symbols to store the original array of bytes and restore it later, but i'm still learning, i would like to know if it's possible and how to do it. Thx

registersymbol(spr)
alloc(original_bytes,5)
registersymbol(original_bytes)
original_bytes:
readmem(spr,5)
spr:
db 90 90
[DISABLE]
spr:
readmem(original_bytes,5);
unregistersymbol(spr)
unregistersymbol(original_bytes) |

There's other way:
| Code: | [ENABLE]
aobscan(spr, ?? 05 0F 57 C0)
registersymbol(spr)
label(original_byte)
registersymbol(original_byte)
[spr]:
original_byte:
spr:
db 90 90
[DISABLE]
spr:
db original_byte
db 05 0F 57 C0
unregistersymbol(spr)
unregistersymbol(original_byte) |
This will set usersymbol "original_byte" to 570F05XX:
| Code: |
[spr]:
original_byte: |
And this will take only "XX" from "570F05XX"
Of course, when you are using 64bit CE, usersymbols will be "8877665544332211" instead of "44332211".
But, it doesn't matter, db will only take "11", dw will take "2211", dd will take "44332211".
