Without going too much into detail: Basically, there are two kinds of "turbo tapes". Those that require some code/routine to be present in RAM (or a modified ROM/cartridge) to access the saved programs and those which are "included" in the saved program.
Turbo Plus - a very fast cartridge based turbo tape - belongs to the former category. Programs saved with that turbo require the cartridge to be present for loading the programs again.
The latter ones are more popular because everyone can load those programs. Simplified, the "turbo tape loader" is hidden in the file name. Only 16 chars are displayed the rest can be "used" for some code (e.g. a turbo loader) which is auto-started by redirecting some vectors. Very simple but very effective Many (if not most) of the commercial releases include such a turbo tape. Among the well known ones are Novaload and the KINGSOFT turbo.
Both types of turbo tapes worked with a standard datasette (most ppl used the 1531 datasette) and thus, any device emulating the datasette should support both of them anyway.
