Ugh, you and a lot of other people really need to learn how to make programs that can work with and without headers. Surprisingly, it's very easy. Do the following:
When opening the file, get the length of it (save it if necessary). MOD that length by 0x8000 (32,768 in decimal), which is the standard size for one LoROM bank. If the result isn't zero, then you have a header. Likewise if it is zero, the rom has nothing. Take this result and put it in a variable (in all of my apps, I call it nHeader).
Next, when calculating addresses or just fetching stuff, use the base address as if no header was present, but add the header's variable so if one is present, the location would still be correct. Example:
nFile[0x3400 + nHeader]
That will get what is at 0x3400 (base address), and if the header is present, it will be +0x200 (512).
The only tedious part is you would need to do this for all things that edit (or make a macro that adds it in automatically for you).
Simple, yes?
