A little cat.
A whole world of pixels.
Explore the sprites, lettering and sounds tucked inside Alley Cat. Decoded from your original game files, one pixel at a time.
The gallery contains mapped sprites and tiles of the IBM PC and Tandy 1000 editions (the Tandy catalogue uses the IBM addresses shifted to the Tandy data segment). Unmapped content and other files are accessible in the data explorer; this is not a complete named asset catalog.
Words from the executable
Printable ASCII runs (at least 8 characters), with file offsets. Some matches may be binary data rather than game text.
Small speaker. Big personality.
The title melody is stored as note indices and PIT divisors, not a recorded audio file. Listen to a square-wave reconstruction at the original BIOS tick rate.
Other effects are generated by game code, not standalone sound assets. Their bytes remain accessible in the data explorer. Title playback is available for the verified IBM executable (PC speaker) and the verified Tandy executable (three SN76496 voices).
Leave no byte unexplored.
Inspect every byte of any selected file, including unmapped graphics, tables and code. This is a manual interpretation, not an identified asset.
