 Posted: Sat Oct 09, 2021 8:24 am Post subject: Help: How to fix <<15:offset too big>> error |
 |
|
First the game was crashing because of this far jump issue (14 byte jump) (Final Fantasy XV is a 64 bit game). So i adjusted the code, now that's why there is lot of opcodes in originalcode. That fixed the crash, but then I was getting this error "<<Failure allocating memory near 1484257CF>>" so then I removed the 3rd alloc parameter. Now that that's done. As soon as I removed the 3rd alloc parameter, i'm now getting this "<<15:offset too big>>" error. How can I fix this? Dark Byte xD helpppp. Btw where it says line 15:offset too big, line 15 in this case is this | Code: | | xorps xmm0,[ffxv_s.exe+3085C00] |
Here's the script:
| Code: | [ENABLE]
alloc(newmem,2048)
label(returnhere)
label(originalcode)
label(exit)
label(floatVal)
newmem:
push rbx
mov rbx,[floatVal]
mov [rax],rbx
pop rbx
originalcode:
movss xmm0,[rax]
cmp byte ptr [rbx+00000084],00
je ffxv_s.exe+83857E3
xorps xmm0,[ffxv_s.exe+3085C00]
exit:
jmp returnhere
floatVal:
dd (float)200
"ffxv_s.exe"+83857CF:
jmp far newmem
nop 6
returnhere:
[DISABLE]
dealloc(newmem)
"ffxv_s.exe"+83857CF:
movss xmm0,[rax]
cmp byte ptr [rbx+00000084],00
//Alt: db F3 0F 10 00 80 BB 84 00 00 00 00 74 07 0F |

you can't do
| Code: |
xorps xmm0,[ffxv_s.exe+3085C00]
|
in a far code block
replace it with
| Code: |
push rax
mov rax,ffxv_s.exe+3085C00
xorpd xmm0,[rax]
pop rax

You could also just allocate newmem near ffxv_s.exe to allow for RIP-relative addressing. No 14-byte jump needed, no indirect addressing modes...
| Code: | | alloc(newmem,2048,"ffxv_s.exe"+83857CF) |

I tried that with the far jmp, but get another error (different error) when trying to activate script. this is the error:
| Code: | | <<Failure allocating memory near 1484257CF>> |
I think if I try that without the far jmp, this error goes away, but it crashes regardless because game keeps doing this far jmp thingy
