Help with _MemoryWrite please

[xtrax]

Hi i am struggling with something that seems like it should have

a simple answer and I could use a little help please.

What i am trying to do using nomadmemory is write a mov eax,06AC0000

if i do this using already set decimal it works fine like..

#include <NomadMemory.au3>
$jumpy = 28655485112
$pid = WinGetProcess("[ACTIVE]", "")
$memid = _MemoryOpen($pid)
_MemoryWrite(0x00495421, $memid, $jumpy, 'byte[5]')

but the problem comes when i want to allocate some memory

and try to add the 0xB8 to the allocated address like

#include <NomadMemory.au3>
#Include <Memory.au3>
$pid = WinGetProcess("[ACTIVE]", "")
$memid = _MemoryOpen($pid)
$jumpy = _MemVirtualAllocEx($memid[1],0,128,$MEM_COMMIT,$PAGE_EXECUTE_READWRITE)  
_MemoryWrite(0x00495421, $memid, $jumpy & "B8", 'byte[5]')

ive tried doing it quiet a few different ways using different Hex2Dec funcs

and swapendians i think im just confusing myself more and more

so any help would be greatly appreciated.
