so, step 3: The checksums.
I hack out the checksum function so that when it's called, it just writes the "correct" answer into the return value.
I do it at the point where checksum_memory() is implemented, not where it's called, as there's two visible calls to the checksumming function, there may be more. this way it'll always return the right value.
(assuming they always checksum the same part of memory! a fun trick would be doing different chunks of RAM... but not here)

so I have a hack that works: I don't think I trust it though. I'm going to change it so the right memory gets into RAM at the right places, just to make sure there's no additional side effects.
There's random values in this sector, after all: what if the game is using them to multiple enemy damage or something?
