I think by that they referred to audio cassette tapes specifically, not the custom tapes used for backups these days nor the tape reels of the 60s/70s. They don't use audio as an intermediate format like the 8-bit era tape drives did. As cleaning up this audio is the main gameplay mechanic here, it makes sense that that sentence refers to audio tapes specifically.

Yes, I confirm that. The game will operate on 2 levels: audio tweak and software processing on 8bit era data.

The main appeal about 8bit era is that the data quantity is low, and this allows some nice bit level gameplay mechanics.

This works nicely on 13-byte (104 bits) headers, but it won't work on gigabyte(8623489024 bits) files. It hasn't stopped me to joke about it: http://caffeinewithdrawalgames.com/games.html#TRS185Tb
