Hi! im trying to retrieve the 4byte hex value from the cheat table to compare in Lua, the problem is, at least the way im trying to do it, the hash is "mirrored" so instead of getting, for example, the hash
2BEC3CBE i get BE3CEC2B

The code im using is:

Code:
local addrhash = getAddress"[VehTweaksPtr]-4" --Hash
print(string.format('%02X%02X%02X%02X', readBytes(addrhash, 4)))
if readBytes(addrhash, 4) == 'EEF345EC' then


Any solutions you can point me to?
Thanks in advance!

That's not a hash; that's just an address.

Multibyte values are stored in little endian: least significant byte first. e.g. the 4-byte value 305420988 (0x12345ABC) is stored as the array of bytes BC 5A 34 12.

If you want to print an integer in base-16 (hexadecimal), use the hexadecimal format specifier:
Code:
print(("%08X"):format(305420988))


To read a 4-byte integer value at an address, use readInteger:
Code:
if readInteger"[VehTweaksPtr]-4" == 0xEEF345EC then
  -- ...
end

Edit: BBCode typo

Many thanks!
I searched wiki for format, could not find it anywhere.
I would never get there by myself.
Thank you.

string.format is part of Lua itself. See the official reference manual for more information:
https://www.lua.org/manual/5.3/manual.html#pdf-string.format
It's more or less C printf:
