Not that TZX is really much better... or at least the tools that work with it aren't, and there are so many undefined edge cases + things that don't belong in a cassette format at all making it a bit of a nightmare.

massive oversights like not having a checksum of what the raw data should decode to with a correct decoder make TZX a poor archival choice.

we've very much been left to deal with what people chose to leave tho, guess we should at least be glad to movement of trying to convert everything to snapshot memory dump files instead was quashed fairly early (although some dumps still only exist in that form)
