CHDBOY

CHDBOY is an Android port of the CHDMAN tool that converts disc images (BIN/CUE, ISO, etc.) into compressed CHD archives. CHD (Compressed Hunks of Data) is a lossless compression format that efficiently combines multiple files into a single compressed archive, significantly reducing storage requirements while preserving perfect quality of the original media. This app provides a mobile-friendly solution for compressing your game backups, saving valuable space on your device without any loss of data.

Highlights Smart mode detection: Automatically picks createcd or createdvd based on your source so you never guess the right command. PSP-aware compression: Uses the recommended hunk size for PSP ISOs to keep conversions compatible and efficient. Duplicate CHD protection: Existing CHDs with matching names are skipped to save time. Background-friendly: Accept notification permissions so conversions can finish even when the app is closed. Lossless space savings: CHD shrinks multi-file disc images into a single lossless archive.

Getting Started Install the APK. Use the Android Storage Access Framework picker to select the folder that contains your BIN/CUE/ISO files (no legacy storage permission required). Confirm the files you want to convert. Wait for the notification when compression finishes. Large ISOs can take a while, so let the app run in the background or rely on notifications.
