trying to pad bin (LAQ2) for my 98 mustang 3.8 using stacker but my bin size of 216k is not listed in stacker trying to pad to 256k any help from someone would be great.
You need to use a hexadecimal editor (such a HDD Software's 'Hex Editor' v2.0) to insert null data before each of the 4 banks of code/data in your bin so that the banks start at 0x2000. It's good practice to fill the null data with values of 0xFF.
