===> is the following correct?
1) you read the save file into memory, compress the data, write the
compressed data to a physical file.
2) you read the physical file into memory, decompress the data, write
the decompressed data (should be the same as the original save file
at this point) back out to a safe file.
3) you try to restore from the save file you just wrote, but the save
file is corrected.

===>no, the "learning" is unique to each save file, but the details
depend on the compression algorithm. The phrase people use that
the compressor is "adapgtive". This is a big and interesting subject.
