Yes, only a one byte checksum.
However, the checksum is not stored, it should be 00, so I add a byte to obtain 00.
Well, a 1-byte checksum is a quite simple method - how does the program react when it detects a wrong checksum?
I remember such a situation for any other ROM that I've patched, and it actually returned an error message (I've just skipped this error routine).
