C64 T64 Tape Preview.
At a glance
| Purpose | A Commodore 64 tape image in the T64 format: a header and a directory of the programs stored in the file. |
| Extensions | .t64 |
| Poka parser | poka-t64 |
| Viewer | poka-metadata-card-viewer |
| Depth tier | Metadata card (see Depth tiers) |
| Breadth tier | B4 Summary (see Breadth tiers) |
How much Poka reads
B4 Summary. The container and metadata are read and summarised (counts, properties, structure), but the main content is not rendered.
Confidence: medium (the reviewer read the code). Basis: Reviewed 2026-10-26: read parsers/poka-t64/src/main.rs (219 lines) and plugin.json. No unit tests or tests/samples.rs, and the corpus has no .t64 sample. Covers .t64. The card reads the header (magic, version, maximum and used entries, tape name) and up to 256 directory entries, listing the first 16 with name, size, load range, entry and file type and data offset. Judgement: B4, because the directory is listed but no program is extracted or shown.
What Poka does not read
- Program contents are not extracted, listed or disassembled
- Only the first 16 entries are listed (and at most 256 read)
- The header's used-entry count is trusted and not cross-checked against the directory entries
