Search And Replace For Array Of Bytes?

[FouGilang 0]

let's say that i have this array of bytes known already, for example :3A FF 00 00 3A FF 00 00 3A FF 00 00 XX XX XX XX 3A FF 00 00 3A FF 00 00 3A FF 00 00 YY YY YY YY and so on (the original value of the XX XX XX XX and YY YY YY YY has been found before)now i want to replace the XX XX XX XX to another value as defined in the sourceyou might say that i could just use write memory, but i found out that in some cases the addresses are different, while the array of bytes still the samecan it, by any chance, be done?
