It turns out that “Insector Hecti In The Inter Change”, converted by “Digital Design”, uses the same tape loader as “Scooby-Doo and Scrappy-Doo”, developed by “Digital Design” too (mostly the same team members).
However, CBM Data CRC32s are not the same, which makes discovery of further tapes using the same loader a little bit longer a process.
“Atom Ant”, “Ruff and Reddy in the Space Adventure” were published by Hi-Tech Software Ltd, copyrighted in 1990 by “PAL Developments” but developed by “Twilight”. They use Visiload so my current (yet early) impression is that the loader used by “Scooby-Doo and Scrappy-Doo” would be best referred to as “Digital Design Tape” loader as it seems it might have been used almost exclusively by them.
Furthermore, “Augie Doggie and Doggie Daddy” was converted by “Digital Design” (very same team members as “Scooby-Doo and Scrappy-Doo”) and published in 1991. It uses the loader referred to as “Ash+Dave”, which is just a variant of what I am referring to as “Digital Design Tape” and initially called “PAL Developments Tape”.
