ROM checksum failed

I have an .asm file that compiles and I get a .hex file that uses on the Z80 processor. Now when that is being transferred to using Quartus, I get ROM checksum test failure (even though memory locations are the same as what was used on the legacy Z80 processor) 

 

Anyone can help me with why I'm getting this fail? Thanks.

Is it because your checksum depends on unused areas within the ROM which are not explicitly specified in your HEX file? You'll get different sums depending on whether your unused locations are 00, FF or random values.
