Could we have the .save file in a format which is easy to read. - Page 2

I've actually tried something very similar, and I was actually surprised that (at least with the libraries I tried) JSON serialization actually adds a considerable overhead to just writing out the save game data compared to the current situation. (My experiment was in ToME 2, but I'd assume it's pretty similar in Angband -- I don't think the code has changed that much.)

Some of this has to do with the absurd overhead of serializing e.g. each dungeon tile as individual strings, etc., but...

Amusing story: originally thw bing search engine did all its anysis on json or a similar format, but a performance analysis showed it was spending 50% of CPU time in binary-decimal interconversion, and a bunch more time just parsing the files. It is a prohibitively costly format for large datasets.
