v1.2.1

• Fix bug when converting images to c64 prg using 16-color palette

v1.2.0

v1.2.0 Release Notes

New Features

• TAP & WAV readers — c64util can now extract program data from standard .tap (C64-TAPE-RAW) and .wav audio files. Pulse-based tape decoding converts raw audio into C64 programs.
• Image to C64 converter — New image reader converts images to C64 hi-res bitmap format. Includes a quantization engine and an image_viewer.prg that displays converted images on the C64.
• Quantized image preview — Terminal preview of quantized C64 images via ASCII blocks.
• Text-mode turbo loader option — Added support for a text-mode turbo loader variant alongside the existing bitmap loader.

Bug Fixes & Improvements

• Shortened silences in raw cycle data for more compact turbo tape output
• Fixed formatInfo() to print directly and support all file formats
• Fixed multi-channel WAV sample indexing

Other

• Updated README with expanded documentation for c64turbo, image viewer, and TAP/TAP-WAV import notes
• Package version bumped to 1.2.0

v1.1.2

• Fix turbo loader checksum and random load errors, improving reliability on real C64 hardware.

version: Patch release v1.1.1

Release Notes (since v1.1.0)

Audio Player Improvements

• Added an audio buffer (~200ms) to the WAV player to prevent sound interruptions caused by timer scheduling jitter
• Pre-fills the speaker buffer before playback starts
• Dynamically calculates how much data to write each tick based on hardware consumption rate
• Pads with silence near end-of-file to avoid partial underruns
• Removed return value from playWavBuffer (now returns void instead of boolean)

Player TUI Fixes

• File selector now remembers the previously selected file index when looping back to select another file
• Fixed progress bar display (now correctly uses 0-100 range)
• Adjusted TUI layout dimensions for proper rendering

Writer Improvements

• Increased chunk size from 64KB to 1MB for buffered I/O
• Extracted appendToOutputBuffer helper method for cleaner buffer concatenation
