There’s Bink variant without any samples known but with decoder present — Bink version d (aka Bink 0.6b). While it’s version closer to Bink-b (aka 0.5b) it’s the same in operation principles with all later variants (telltale sign is integer DCT instead of floating point one in Bink-b). Here are some details on how it differs from later Bink variants.

The main difference is lack of scaled blocks, hence block types got reshuffled as well:

• type 1 — pattern run
• type 2 — intra DCT block
• type 3 — inter DCT block
• type 4 — inter DCT block (lossless)
• type 5 — single colour fill block
• type 6 — pattern (2-color) block
• type 7 — motion block (looks like it uses overlapped copy like Bink-b though)
• type 8 — raw block

In other words it’s not that special and demonstrates the evolution of Bink versions.
